Last two done. I expect to shoot the demos tomorrow.
Ran into some problems with these builds. On my Rabbit Hole I had Q2-Q4 socketed while I was testing out my build and I left them in when I boxed it up. The enclosure lid came into contact with one of the transistors and shorted the output. So, I removed those sockets (word to the wise). Also, I had pulled an old 1590A bypass board out of my reject bin without checking it and the LED wasn't lighting up so I ended up putting in a little wire jumper to fix it.
On my Dust Bunny, I ended up having to re-build it as I desoldered one time too many and lost a couple of pads. No big deal, only took about 15 minutes. Anyway, I ended changing the Q2 bias resistor to 68k from 100k and then biasing Q3 to about 5v. Now I am really happy with it!
So, yeah, even I run into plenty of troubles now and again building. You just gotta keep at it and solve the problems.
