My DR-110 went mad an hour before a show. Scary, could
have happened on stage.

Now I have it on the bench.

The clap currently sounds like a kick and there is a constant Atari 2600'esque
textured white noise super loud at all times.

My guess is that this is part of the noise component of the clap sound.

Anyone run into exactly this? Would love some tips.

It must be a transistor that failed or a cap.

Failing any tips, I am going to replace the E-caps: C48, 49 and 50.

and then transistor Q15 then Q16 then Q24 with a test in between each.

So much work for a $40 drum machine but I am very fond of it.
