View Full Version : Never ending Hi Fi Pain - VTA adjust on Technics EP-250

No secret that I'm a big advocate of the Technics tonearm, on the fly vta system.

I find it superb when dialing in the cart sweet-spot during tonearm/cart set up.

It's the reason why I went with the Technics EPA-250 tonearm over other very good options, for my SP10 tt, as the carts I use tend to be very vta adjust sensitive in terms of set up and nailing their narrow sweet-spot window. Once in through, in my experience, the system audio replay is fantastic.

However, for the second time I've had to revisit set / redial in the sweet-spot via vta.

At first I didn't immediately realise that the vta adjustment had actually moved and put the loss of focus, splashiness, mid upper frequency lift, ear fatigue down to my speakers and/or maybe my new acquired tonearm cable, changing and bedding in.

Then one day I looked at the vta marker and noticed the red line marker was not where I remember it being when I'd set the vta, so I got to trying to dial it in again, something i hate doing and find takes a long time to get right.

Eventually as always I got there.

The music/sound over the past week or two has been again superb, even up to last night - excellent.

Today though, sound not right. I've looked at the red marker and the vta has definitely moved. I took a pic last time for reference, which also confirms.

After the first time, I happened to come across this https://db.audioasylum.com/mhtml/m.html?forum=vinyl&n=962334&highlight=technics+epa+100&r=&search_url=%2Fcgi%2Fsearch.mpl%3Fforum%3Dvinyl%26s earchtext%3Dtechnics%2Bepa%2B100

This had crossed my mind before, as I didn't realise that whilst i was getting the Technics on the fly system, my EPA-250 and the expensive EPA-100 does not have the vta lock, which they added later to the tonearms on the 1200/1210's.

So bottom line is, the same ole, one step forward, two backwards, as always seems to be the case i'm finding in this game. I'm pi&&ed to say the least. obviously I cant/wont/dont play my system until I've mailed set up and it is sounding right, also, I really really cant be asked with trying to re-dial in, every few weeks or so, it is too time consuming and fatiguing.

I really didn't realise that the EPA-250 vta adjust doesn't lock, causing the arm pillar to sink, little by little with use. It's a lovely, quality arm but like so much in relation to vinyl / hifi, is flawed ! :steam:

Not sure what I'm going to do, going forward, but fed up with it to be honest :(

Hi Robbie, sorry to hear it. Must be a pain after the micro seiki which did have a lock. I don't know anything about the EPA 250 but it might be worthwhile having a chat to Steve at Magna. Could some sort of grub screw be fitted or some other modification be made to increase the friction ? If anyone could come up with something clever it would be steve.

Steve was the first that came to my mind as well. Be surprised if he can't come up with a fix.

Simple fix is putting it back on the same spot if it moves?

Tiny line up mark would do.

Er nah! Great arm I don't doubt but as you know I love the super smooth usability of the Technics on the fly system.

The best for dialling in the vta/sweetspot in my experience and makes life a lot easier with the 'fussier' stylus profile I use. BUT, sadly for me this one doesnt have the vta lock which they added later to the system otherwise, would be perfecto !

Also, It's nice we dont all have to go for the same tonearm option..... ;) :D

:D Damn excellent tonearm from all I've heard. I'd have one myself if it had on the fly like the Techie (with a lock as well) :lol:

That would seem to be the best solution, for someone with the tools and talent. Drill, tap, grub screw.
