5F6A Bassman Volume

[yurka]

Just completed a 5f6a bassman amp, fired it up with no smoke, all the voltages check out perfectly(verified 4-5 times). Plugged in a guitar and it sounds great, the only issue Im having is I know the amp isnt putting out enough volume, I can completely crank the amp without any breakup, and my ears dont bleed. Any suggestions to where I should start?

Found a bad solder joint on the wire connecting the NFB, works great now!

Without NFB it should have been much louder than normal.

Well that is interesting. The amp seems to be as loud as it should be now, but Ill go back and verify the NFB again.
