Thank you Jake. Found my problem after a little chopsticking - sigh - cold solder joint on the OT input from V2. Fixed that and it's alive now. Output volume seems weak tho' - if I crank Vol and Master Vol ALL the way up, it gets to about "easy listening in your living room" volume. I'm guessing this isn't spec, compared to my other Champ and 5E3 builds, for which turning Vol to 10 is not allowed in the house. I have the 3.5W Hammond 1750A OT hooked up to a 8ohm Weber Signature 10". Any tips on where to start chasing that down that would be greatly appreciated.
