The build doc says both of the 308s should have voltages at pins 1 and 8. On the one I built those pins have zeron voltage on those pins. The schematic is not clear which pins are which on either IC. All the other pins on these 2 and the other 2 ICS are dead on correct.
TIA
That's a bit of fail on my part. I don't know why I don't have the pin assignments in the library part for that but I will correct that for future schematics. Anyway, pins 1 and 8 are connected through the 33pF cap. I just cross-referenced the voltage readings of the Dragonbeard, Slow Loris (Rat) and the VFE AlphaDog (Rat) and they are consistent with the voltages reported in the Dragonbeard. But I apparently I got different readings on the Runt (the 1590A version of the Rat).
So, it's more likely the pin readings are not that important or possibly I misread them on the Runt. Are you having any problems with your build otherwise?
Just finished putting it together. No sound yet but I still need to check some other things first.
Thanks for the quick response.

Hey, finished it and it sounds great. Quite a nice ranges of sounds.
Okay, great! Did you have a problem that you were able to solve (you said previously you had no sound)?

While checking voltage I pulled IC1 and then forgot about it. So wiring it to the breadboard didn't work.
