Title: Found Problem...
Post by: skypn on April 22, 2020, 03:55:33 PM
Just don't know the fix 8)

Consider this Bass Fuss...

I have good strong signal at the collector of Q1. Pass the 120pf cap, not so much, and rotating to pot does nothing to increase the signal on pin2. I swapped both cap and pot.
I have bread boarded this circuit a couple times with these values, so I wouldn't think that's it. I must be on the right track, but keep missing the train.
Any insight would be greatly appreciated.
TIA

The output cap should be 100n. 120pf is way too small.

Thank you Madbean, that was the problem. I wonder why the little cap worked before?
