So, I have built an EHX Bassballs, and in the testing progress I've bumped on something I haven't seen before.
I connected the vero to my
test box, hoping for that first-time-working magic but instead I got no sound at all. (no surprise there...)
I was making sure my test box works before I blame the circuit, so with no wires attached I touch the "output" and buzz came out of the speaker as intended. When I connected the circuit output though, no buzzing occurred, even by sticking the screwdriver in the connection. Generally no sound no matter what I touch on the board...
Does that mean my "signal" wire is grounded?
Also, while I'm here, it's the first time I use film capacitors. Is there something I may have overlooked about those and may be causing the problem?
I didn't felt this was a "debuging forum" post because: I've checked the board by eye, I've checked it by comparing an opaque pic with the layout, I've checked row by row for connections, I've measured Ic and tranzistor voltages (they seem right compared to the ones found in the bassballs' page)...
The real question is how is it possible to connect anything to the speaker and when touching it stays dead quiet.
