View Full Version : Mission 774 Arm
Hi,
the clear out begins......
Mission 774 Arm complete with rewired wand, counterweight and baseplate. Please note is it being supplied with the baseplate shown in photos 4 and 5 NOT the one fitted to the turntable in the 1st photo. No mounting screws are included I need these for the TT it's currently fitted to

As you can see there is no sag in the counterweight ( very unusual ), the cable is knackered ( supplied ) I am also supplying both the wand and baseplate with connector so a new cable can be added. The arm rest is captive on the little pillar it sits on and swivels as it should and that again is unusual as they normally fall off and require gluing back on.
The grub screw is missing from the baseplate to hold the arm pillar in position, however this can be easily replaced as well.
The anti skate bias comes with 1 weight and the arm also includes 1 ( thin ) damping trough pin. The item is not mint, the wand has been touched up by the previous owner in a few places but overall it's in decent condition.
Please note the text in bold as no returns will be accepted for not reading the advert properly ;)
£220 including next day postage within the UK.
This, like my mayware arm gets very well recommend by Geoff and co. Good luck
if it helps with the sale,i can provide a new arm lead that brian made me for when i had my 774,its one of his super duper silver leads.

That's a great idea, I never got around to doing that with this arm as it was only a spare. the one I used is really needing done too but since I've moved up to the FR 64FX neither of my 774's are really needed.
I'm sure any buyer of my 774 will be in touch.
Thanks :)
i dont blame you mate,the fr-64 looks a lovely arm,i bet it sounds nice too.

Hi Mike, I am interested in this but as someone with no knowledge of these things I am a bit concerned about the things that are not included & would have to find myself, ie cable & correct size screws/grub. What deck is the arm board for, I want to put the arm on a Rock Elite?

What deck is the arm board for, I want to put the arm on a Rock Elite?The grub screw is a hex head, not sure of the thread size but I write think it's pretty standard, I'm sure someone on here will help in telling us what size is required.
The output cable gets soldered onto the little plate that's supplied on the underside of the mounting plate.
Jamie123 has a cable already made up to do the job that he was prepared to sell to any buyer of my arm. So that might help you.
The arm is an SME fit so you would need an SME armboard for your TT.
Hope this helps.

Hi Mike, it does help thanks, let me have a little think..........
Hi,
No worries, pretty sure for another £40 or so you'd have a decent arm and would just have to source an armboard for your deck.
I'm only selling as I have 2 that are no longer needed since buying a Fidelity Research FR64FX arm.
Although one is fitted to my Michell Focus One.

I have to say it is the arm board that worries me most Mike, I have been having a scout around & come across a few people who have struggled to get one & have been left hanging for ages & there is no point me buying a deck if I can't put the arm on & use it.

Hi Mikey B
Is this arm still available for sale? If so, could you PM me?

tom
Hi Tom,
Yip still for sale. Last chap found it difficult to source an armboard for his Rock TT.
Let me know if you require more info.
Cheers,
Mike.
need a few more posts b4 pm system kicks in
Thanks Mikey B (and Struth)
So...
I think i have the arm board issue sorted, as I have Jayman's PLC-1700 including the (beautifully fashioned) armboard he made for his Mission 774 and I think Jayman can also help me out by selling me his cable.
So... my main concern at the moment is the missing grub screw and, I guess, the mounting screws (which I guess are easier to source)...
Did you find out any more about who might be able to supply one?

I'm reasonably sure all the threads on the 774 are Imperial. Should still be easy enough to obtain a suitable item though.
would think so, or ba if not. both should be available on likes of ebay
Aha - that's a good tip. I'm sure I'll be able to find something.
So - Mikey B - I'm up for this. What are next steps? Not sure I can Pm (or be pMed) just yet as I only just joined...

I'm sure somebody here could come up with a suitable screw (no rude answers please :)). I'm assuming it's the column/stem pinch bolt? I may even have something to do the job myself.
Hi,
Yes it's the one that secures the arm pillar within the collar and allows it to rise and fall once slackened.
I actually have a screw but it's the one on my other 774 arm that's now fitted to my Michell Focus One TT, I'll try and see if I can measure it as see what's size we need.
I'll post a photo of the screw to see if anyone can identify the size too.
At work just now but I'll sort this out tonight.

At the moment I'm putting this together for my brother (to replace a Project Expression III). He's got my PL-71 on loan and has been enjoying it, so I said I'd try to find him something similar... I think we're probably surpassing it by some distance now!

no worries mike,you've been good to me with the zyx :cool:
it certainly will be a good set up on my pioneer tt.
Now paid for and will be posted out today [emoji4]
Tomb sent you a PM regarding non postage today and the reason why, I've tried to PM you but I don't think you've been online yet.
This is just in case you haven't received the PM.
if its urgent mike i can pass his number on to you via pm?

Pm on its way
Well he's bought my lead for the 774 so I'm sure it will still go ahead mike
Hey Mike,
Just seen this - how strange. Don't have card reader with me so can't check until I get home, but will try to figure it out then.
Tom
You've not done .com again have you?? Lol
Hi Tom,
No worries, I'll hear from you later if you get a chance to check it. It's all packaged ready to go, so the quicker you let me know the better, I think last posting for me today is 15:45 for guaranteed Saturday delivery. I'll phone my bank and see if it's pending into my account, they should know if a payment is due in.
lol it was Bank Transfer ��
Here are a couple of photos of the grub screw you need for the collar. Not sure if it will help but someone might be able to identify its size.https://uploads.tapatalk-cdn.com/20170930/294b70d33fbab198c8f8da9df95c13d0.jpghttps://uploads.tapatalk-cdn.com/20170930/4c4f47c553b748d17d451d2eddae025a.jpg

Reckon there would be one in here?

if your not sure what size,take the arm base to a local nut and bolt shop and try some in the thread.
So... finally got a chance to take the arm base to Clerkenwell screws... after all the excitement about this possibly being something imperial and tricky, it seems to be a 3mm thread... sorted!
Paint and cable arrived from Jamie so will be topcoating the arm board this week and hopefully setting it all up before too long.... can't wait to hear it.
Thanks to all for advice thus far...
Thats good news... thought it looked metric with that pitch..
Great news, thanks for the update.
Hey guys,
So - a little more progress on this...
Got the armband sprayed at the weekend, and got the tonearm wires soldered (thanks to @Jamie for the tip for working out the order) and the tonearm nicely in place. Did a quick 2-point alignment with the Hifi News protractor (see bottom right hand corner of the picture) and a quick test with an old Ortofon OM-10 I had knocking around and all seems to be working well... will try with a better cart once I get it all in-situ, but this was enough to hear
The only problem I am having is how to dress these very thick (and stiff) cables to prevent the solders onto the bottom of the arm base from taking the strain... one of the signal wires has already pulled off, so I'm going to have to open it all up again! Arrggh!
Anybody know the trick with this? I'm even toying with tacking in some little clips for the wires on the inside of the deck somewhere, but it doesn't look like this has ever been necessary before, so perhaps I'm missing something....

I fitted some cable tidies under my TT and then soldered the plate and wire together. It's imperative that the wires are secured because they will come apart if not. It can be fiddly but you'll be rewarded with a fantastic tonearm when youve sorted it.

Just edited post above to fix the main photo !
Haven't got any photos of the cable dressing, but will see what I can do later in the week...
Thanks Oliver...
Yes it really is a pain... the original lead (which I'm not using) seems even stiffer and less flexible so I can imagine this must have been a problem for others with this arm.
Worst case, I could just get some lighter / shorter leads a run them from the arm base down to the sockets on the back of the plinth (which were removed so I could run these leads direct).. That would probably reduce the weight and also the risk that movement of the cable somewhere outside the deck causes these to pull apart...
I had the same issue in my 1210, so I just screwed a plate across the cable on the underside of the deck to trap the cable. It wasn't pretty but couldn't be seen.

I used the cable grip from an old 13 amp plug. The kind that uses two screws. I screwed it to the plinth base so the cable exited backwards.

done that too before. :lol:
Thanks for the tips. I think part of the challenge is the tight angle to get the cable back to the opening on the back of the plinth... wondering if running it through the large circular hole in the bottom of the TT base might work out easier, particularly as it would probably be easier to screw cable grips into that (it looks like some hardboard IIRC).
Will have another look tonight...

16-10-2017, 10:09
The cable can go through the hole, but it still needs securing as flexing from movement will break the thin soldered ends.
Yes - understood. I think i really need to build some kind of jig so I can get underneath it more easily, as part of the difficulty is access... ie there would have to be some 'slack' (At the tonearm end) in the secured cable to allow me to get the tonearm base up (to solder)... if really is a fiddly process!

You could glue a block inside the back of the plinth to bring the supporting clip out to where you want it.

Forgot to give you guys an update... got the cake really well secured with some carefully positioned cable ties (around various points on the chassis of the deck).
Had some fun and games with alignments, especially due to the ease of screwing up the azimuth when adjusting the wand length etc...we had it dialled in ok when I dropped it off a few weeks back, but my brother reckons he’s got a really good Stevenson alignment on it now... he’s confounded as to why it can’t get Baerwald but afaik it’s because the offset angle is fixed at 21 degrees or so...
What do you guys use on your 774s? Perhaps this is worthy of a new thread on its own...?
https://preview.ibb.co/dfLRcm/29_F54689_9_F95_4_EBF_BE68_7_A46696_B6063.jpg
Do Mission quote the offset angle for their 774 arm? I have had a look at vinylengine.com but it only states the effective length to be 229mm and the overhang as 13.6mm. Are these figures correct?
Armed with this information and assuming IEC figures for the maximum and minimum groove radii, we can calculate the overhang and offset angle for the Baerwald alignment to be 18.14mm and 24.1 degree respectively. If DIN figures for the maximum and minimum groove radii are used, the overhang and offset angle becomes 17.1mm and 23.5 degree.
If we look at the Stevenson alignment prescription, the calculated overhang and offset angle are 15.9mm and 22.7 degree.
None of these figures tally with figures of 13.6mm and "21 degrees or so", but are closer to Stevenson than Baerwald. I would imagine your friend was able to set up his arm the follow the Stevenson alignment because he was able to alter the effective length of the arm far enough to set the overhang to 15.9mm.
According to http://www.edsstuff.org/docs/tonearm_specifications.htm,
the relevant values for the Mission 774 arm are as follows:
Effective length: 229mm
Overhang: 13.6mm
Offset angle: 20.5º
Pivot to TT spigot distance: 215.4mm.
Given these figures we can calculate the radii for the two null-points to be 60.5mm and 99.9mm. These are the points that need to be marked on the alignment protractor.
(Compared to the null-points following the Baerwald geometry of 66mm and 121mm.)
