OBsidian T Troubles / Edit FixeD

[petemoore]

I can't get Q4 to act right.
 I'm getting 3.25v at the Emitter and Collector, 4.25v at the Base.
 Measureing 10k from V+ to collector , 2.26K from Emitter to ground, and the 4k7's string seems to measure correctly also, with the transitros pulled.
  It sounds but is weak and gated because of Q4...]
 I have 10k on the collector
 two 4k7's on the base and a 3k3 on the Emitter.
 I've  been through and through and Q4 still has me stumped Grr...
 I'm using 5089's MPSA18's etc.

Nevermore, I got it !
 First I changed the 2k2 I had in there for the 3k3, and that helped but not enough.
 I then tried 14k7 on the collector, and that was worse again.
 The 4k7 parallel to the 10k, [probly about 4k6] did the trick. Voltage jumped up to about 5v on the collector and all funny symptoms were replaced by the beautiful sustains and Chrunches the Obsidian Does So Well, a very Heavy OverDrive Sound.
 Thanks go out to Joe Davisson for this circuit !!!
