Don can you clarify this...

Is the normal tuning switch away from the keyboard ...?

Changing the memory chip TC5514 solved the battery board problem..It now works.

Thank you for the great support.. :D I will look into this and report back. I am also repairing a few old battery boards, I have replaced and fixed the traces on the IC30/31..The counters are now working. But when saving the data is corrupt and i suspect the TC5514. Is there any good replacements fo...

Cheers I wish it was...It's the board but what...?

The battery board is 100% ok...The 366 board will not tune up and there is some kind of distortion going on..?

Never seen this before....Please any pointers..???

Trim pot are a problem with cats...Start there..

Stay calm and start with the power supply checking all the voltages. I wished I had mentioned you should check it every time you recap each board.
It's easy to get lost when recapping a whole synth in one go.

You will get it working again..

Very nice you took the time to post this..good luck..

I replied to a guy wanting to buy a TR808...I was thinking of selling mine (not now) and he asked if it was a black face or brown ect....Mine is more black than brown....

Kind of the usual strange questions you get asked these days...

I also hear that that there are Brown face and black face models....?

It could well be the casio...Why not.

Thanks everyone....I have a my second child coming so i have not got too much into it as yet, Although i have a show at the end of March I am thinking of using it live...Maybe..

It cost me 6k with the DK 1....

Sorry I had to shout it out...Cost me a bloody fortune..

Got to work out how it works..Try to get a normal sound out of it at least.

A MS20 would be a good option....You need a raw sound in there and the ESP section is great.

I feel the problem is on the DEMUX board..
