Hey 
Awesome.
Thankyou.  Yes I've only just signed up. 
As it turned out , I've managed to get both turntables and amp running. 
Luckily just fuses had blown . Not sure what I posted earlier but have modified the tranny in turntables to take 240v from a YouTube clip but running vestax mixer through a an exterior additional tranny.
Be keen to see a service manual .

Hi Meat

I recently purchased one of these mixers and two vestax turntables online.
Turns out it's 100v gear not 240v which is what we have here in NZ.
Looks like all three have been plugged in to 240 v . Fuses had all blown and the turn tables after a transformer mod I found seem cooked
I'm guessing the same for the mixer but looking for a service manual to help. 
When typing in search your thread came up and I see you thanked someone for the service manual.
Any chance you still have access and could share ? 
Thanks.

Also, the mixer is still running after all the tinkering 2 years ago. Wish I had more opportunity to use it myself but hey it was fun using it to mix at parties on in the beforetimes!

Remember parties with lots of people and dancing? Them were the days.

Yes, I've still got all the docs I collected for the PCV-275.

Can't get into my old account so I won't be able to send/recieve PMs until I've got 10 posts. If you put up your email I can send what I've got.

Sounds like it very much could be. Had it once before. Check all ribbon cables and board-board connector seatings for a start in the Berry. Good luck!

Got the little bugger on the scope today. Seems pretty nice. No problems at all.

Took it home. Ran just headphones, no problems.

Plugged it into my ultradrive...  ...HF noise present again. I went rooting and turned up my horns; it's present without the mixer.

So in all, my ultradrive is putting HF noise out of the inputs and the outputs. I think this vestax story is wrapped up for now!

Is this the famous 'frying eggs' ultradrive thing? Anyway, it's probably time to just start another topic. Thanks to all those who have helped or offered advice.

The problem is a high noise floor. High frequency artefacts which are especially noticeable on the monitor headphones.

I opened it up for visual inspection and noticed that the power supply caps had let the magic out. Replaced the 2 2200uF ones in the supply today and it still turns on (yay, I didn't kill it at least!). Sadly, the noise persists on the monitor. Haven't got around to checking if the noise on the 2 crossfader channels is still present also; just been running through the sub channel.

I've a sneaking suspicion that I'm gonna have to just work through all the boards and recap the whole thing unless someone else has a bright idea. Maybe theres a standard place of where to look upstream of a powersupply that's had the caps go pop?

On the plus side. Although many folk seem to diss whats inside a vestax all the original caps were quite nice Elnas.

As always, any help greatly appreciated and if someone should happen to have the schematic then that'd be very handy indeed.
