Re: Snare drum no sound at all
At IC35 I have pulses/envelopes coming from Pin 1 (Output A) of IC35 but nothing from pin 7 (Output B).. Pulses/envelopes are coming into pin 6, and pin 5 is connected to ground as it should be.. Might swap out this M5218L at IC35 and see what happens, as I have a spare..

Re: Snare drum no sound at all
...and at pin 6 of IC 40 (Which is the inverted input) I have the noise hits, pin 5 (input) goes to ground as it should, and pin 7 which is the output I have nothing, but it is connected to pins 1 and 2 of the snare level pot... So I think I have two issues going on - one with the final output stage...

Re: Rimshot not working [SOLVED]
Checked the pot to see if it had continuity to where it should, and sure enough found that the right side pin wasn't connected to anything - I must have damaged the trace when I desoldered it. I used a couple of short wires to connect it to Pin 2 of IC50 and C120 and it's now ticking away nicely 8-)...

Yay! Great news!

Re: Snare drum no sound at all
So I'm still working my way though - I have 4v pulses at base of Q44 but with a -4v offset. On the other side of R258, which connects to the base of Q44 I have the trigger pulses

Re: Snare drum no sound at all
Okay so it's an error in the board file - the pcb is printed correctly - r246 below r244

Re: Snare drum no sound at all
So trying to trace it round using the schematic here: http://hardware.freepage.de/raf909/ Not very far in, I have a trigger signal at the base of Q39, but then at the base of Q40 my digital oscilloscope is reading out of range (I have it set at 5v, which is the maximum), so I'm checking the values o...

Re: Snare drum no sound at all
Any ideas anyone? I just opened up the schematic pdf again to try to have another investigate but it's impossible for me to follow with all the labels on top each other..
