Hadcock temporary bodge, I'm still waiting for the adaptor plate.

Arm fitted and ready to go. Note slightly iffy position of bias weight, a bit of attention needed here.

pure sound
01-08-2008, 17:22
looks great, how does it sound & what did you have before?

Mike
01-08-2008, 17:34
2nd part first; I had a Technics SL120 which I only used for a few hours last week, then this came along. Prior to that I had an LP12 - err, for 18years!

How does it sound?... Hmmm, rather poor to be honest! Same as the SL120.

But it's early days yet, pretty much everything is new to me. A lot of it actually IS new, like the cartridge and phono stage. I've also never used ANY of this equipment before so don't have a baseline to go from, also the tonearm has been modified (and possibly spoilt) be me in an attempt to turn it into a 242.

Much tweakage ahead! :scratch:

Marco
01-08-2008, 17:57
Looks good, Mike. Did you listen to it first with the 3009? That way if it sounded pants you could (kind of) eliminate the tonearm.

I think your problem is likely to be the phono stage. It probably needs some further tweaking.

I'd try and borrow a commercial design and see what happens. When you come down we can run your T/T through the Croft and step-up tranny and see what it sounds like then :)

Marco.

Mike
01-08-2008, 18:04
I didn't buy it with the 3009 Marco.

But I've found that cleaning the big ball of snot of the stylus improves things no end. Fancy that eh? :lolsign:

Marco
01-08-2008, 18:15
Ah, I see (regarding 3009).

LOL. You need to keep your records clean, matey - vinyl hygiene is paramount :smoking:

Mind you the AT is somewhat of a fluff magnet :eyebrows:

I'm looking forward to hearing it. One tip with the Hadcock, btw, which George told me, is to use it with just the main counterweight balance, and leave the small one off. When I had the Integra it made quite a difference.

Worth a try maybe?

Marco.

Everything is worth trying at least once. Well, mostly! :eyebrows:

The AT has an incredibly fine stylus, on some disks it seems to be digging out some sort of waxy snot that me old Knosti has obviously failed to shift.

Marco
01-08-2008, 18:48
Yeah, I noticed that when I had one. It does have a very fine stylus. I'd defo do the C/W thing on your Hadcock. Also, the bias adjustment weights definitely don't look right to me. Any chance of a close-up of that bit?

What are you tracking the cartridge at, btw? I found 1.8g was best with the AT. It takes a good few album sides to run it in.

Marco.

Mike
01-08-2008, 19:10
Bias weights sit on the edge of the, err, grey bit, when the arm is in the rest but it's in 'fresh air' over the entire playing surface.

It's tracking at 1.75g for now.

There's plenty of tweakage to be done yet, for a start the standard wibbly wobbly feet can go in place of some RDC cones & cups, but I've only got two spare cones ATM.

Biggest problem though, is Mrs H has discovered the '45 button' - I can look forward (not) to the next few hours of her ancient 12" singles. Depeche Mode currently. :doh:

In fact I've more or less been booted out, She loves the thing!
Now that wasn't in the plan! :scratch:

Oh. Now she's onto Pat Benatar (?).

Marco
01-08-2008, 19:17
LOL. Is she having a wee boogie? :dance: :eyebrows:

How the bloody hell am I supposed to do that when I can't get anywhere near the damn thing? :confused:

The first thing that strikes me is the double weight on the bias string. Is that how it originally was or have you added an extra weight? Mine only had one bias weight.

The other thing is I seem to remember in the manual that it said to set up the spindle holding the bias weight so that it was parallel to the arm tube, but in your circumstances doing that will probably result in the weights fouling on the plinth.

The bias string should also be tight without sagging.

Is there any way you can rearrange things so that you can get the spindle holding the bias weight parallel to the arm?

Marco.

Mike
01-08-2008, 20:56
Marco,

The bias adjuster came with two weights, so I've left it 'as-is' for now.

I agree with what you say about the thread from the outrigger to the wheel thingy being horizontal, and yes it will foul at the moment. But until I receive the SME/Hadcock adaptor plate I don't know exactly where the base of the arm is going to sit. I may need to fabricate some sort of riser.

I still have my 'cone flap' problem which seems to be reduced somewhat, but there is still clearly a LF resonance issue. I hope all this can be fine tuned out but it seems slightly pointless at least until I get all the 'permanent' bits to hand. Keep the pointers coming though, much appreciated matey. If needs be, I can always turn it back into a 228 or splash out on a new (official) armtube.

It's all looking very promising after a few miles on the clock, it's running in nicely and I'm already thinking it just might be worth a 'Slatedeck'! :eyebrows:


Cheers...

Marco
01-08-2008, 21:02
Nice one, Mike. No worries, matey, that's what we're here for :)

When you get a chance I'd re-balance the AT with just the main C/W and see what that does. Otherwise you're quite right, there are lots of things running in and the set-up is far from optimised. I'm confident that this story will have a happy ending :smoking:

Marco.

Mike
01-08-2008, 21:17
I'm already pretty happy TBH. :)

I just love the sort of retro-futuristic styling of the thing, it puts a grin on my face every-time I use it! :eyebrows:

There's a slight fly-in-the-ointment though... There could be a speed stability problem. It seems that the little magnetic reader thing (the bit that looks like a cassette tape head) needs to be positioned 'just so' otherwise the speed randomly goes off on one. Only on 33 though, 45 is rock steady.

Actually, (don't try this at home kids) if you deliberately maladjust it, it's hilarious!... It wizzes up to an amazing speed. God knows what would happen if you tried it while playing a record, I expect the room would be full of vinyl swarf!

:lolsign:

Its fun when they do this, the first time it happened was when I was debugging a problem with my sp10, and it just lost it, and played the "lets go fast" game. thats when I realised just how different these things are from a little motor, a elastic band and a flywheel. If you get them rearly coinfused they can try and go backwards,

Note: this is the result of delving inside them with logic and scope probes, they are normally well behaved.

Humf... Typical!

The day after bodging the arm on, the adaptor plate arrives. :doh:

Oh well, at least I can try and get it mounted properly now. As I suspected it's just a flat plate that goes over the SME mounting with the correct size slot to fit the Haddy, so some form of riser is going to be needed.
This is a bit of a worry as it means venturing into very dangerous territory. Most people would call it "The Garage"! :sofa:

The height from the base should be adjustable.

Mike
02-08-2008, 09:58
The height from the base should be adjustable.

Indeed it is!... And now that you mention it, removing the silly MDF 'washers' that are fitted (top and bottom) may well give me sufficient range to adjust it.

Top tip, cheers! :clap:

Hmmm... another little headache...

I'm trying to figure out how to fit an achromat to this thing, problem is there's a sort of raised bit in the middle of the platter about 95mm in diameter.

Somehow I need to grind away a more or less perfect circle on the underside of the mat so it sits on the platter properly. :scratch:
