Bassman 5F6A fun Build

[p2pAmps]

Here is the latest project on the bench, a 5F6A (Thanks Doug for the awesome board as usual)

I am messing around with 5881s and 6L6s to see which I like best for this setup.  I added a 1/2 power switch (Pentode/Triode), 3 way Negative feedback (27K-bypass-10K), and also a passive effects loop for fun.  Speakers right now are 2 Celestion Golds (G10 - 8Ω) and 2 Celestion Creambacks 8Ω and so far at least it's pretty great.  I did have to massage that chassis to fit with that top left speaker but I got it done.  I may order my cabinet 1/4" deeper next round, if there is a next round that is :)

Power supply is (4) 20uF/500v caps.  I bumped the bias filter caps to 50uF/100v to hopefully reduce any unwanted 60hz hum, so far so good...  I did change the presence pot to a 25K with a 4.7K hanging off it like the later 5F6As had I believe.  The tail resistor is a 6.8K 2W.  The bass coupling cap is a .1uF.  I did try a .022uF and may go back and fourth and see what my ear likes with these speakers etc.

Transformers are Hammonds:  PT-  290DX, OT- 1750K 2Ω, and the standard 194B choke

Anyway, I am in no way some sort of expert but I do have a good time

Cheers!
Mike
