Weltmeister Claviset/Selmer Pianotron

[Ted]

I have in front of me a Selmer Pianotron. Allegedly the same as an early Weltmeister Claviset.

It contains a PCB with four transistors on it. I don't suppose anyone has a schematic for it? Nothing out there on the interwebs.

Or am I going to have to do the world a favour by drawing it out?

Did you indeed do the world a favour or will I need to draw it out?

No I didn't need to in the end. I found a loose wire and it sprang into life. But its pretty simple. Just an oscillator for the trem and a couple of transistors for amplification.

Thanks Ted,
I have a few faulty caps on the board. I'll get them replaced and see how she goes.

Why not discuss it HERE, so others may benefit?

Happy to answer any questions - I have some notes and took some pictures. Never did trace the schematic as it was a "loose wire" fix.
