I had a spare Cosmo board lying around and thought I'd try building the Lunar Module on it, as outlined in these threads:

Forgive the hodgepodge of parts and huge cap - this was very much a spare parts build. Nevertheless, I can't get the bloody thing to work. I can get the tiniest amount of signal to pass, but no fuzz whatsoever. I took voltages last night and neglected to record them, but IIRC Q2 was getting little to no voltage at all.
Can you guys take a gander at this and see if there's an obvious error or omission?

Just saw this one Dane! Ill take a closer look tonight but at first glance everything looks okay to me.

I was afraid you'd say that :)
I'm out of town at the moment, but I'll try to post some voltages this weekend.
Alright so after looking this over i think Q3 is in there backwards. It looks like you have the collector and emitter reversed. Flip that thing around and see if that does it!
