Teensy 3.2 is fine. Last ones I bought were from Mouser.

I seem to have just fried my second Radio Music. Was removing it from the rack while powered up so I could adjust the trimmer to reduce gain and distortion. When I put it back, I must have shorted some pins against the adjacent module's faceplate - it's dead now.

I removed the Teensy and TL074 and did the voltage tests. Zero voltage anywhere. Suggests I have blown something in the power supply. Any suggestions what to replace?
Maybe try L1 and L2...
I doubt that the ferrite beads or resistors would have blown, especially seeing that there are two reset-able fuses. Try swapping out the teensy with the "other" Radio Music.
I meant the fuses as well... But in the schematics it is very unclear what the fuses are called (they are not named at all). So I mistakenly thought they where called Lx...
:doh: Sorry for that!

Follow up question: Does it have to be a teensy 3.1? Don't seem to be many around now. 3.2 or later.
I have a 3.2 in mine. I think the only difference between 3.1 and 3.2 is that the 3.2 have a beefed up on-board regulator so it can drive more hardware off its 3.3V regulator.
Thanks!

Is anyone working on a higher fidelity version of Radio Music?

It does so much of what I want that other sample players literally can't, but the noise floor really restricts what kind of sounds I can use it with.
