I was expecting a 1x8 cabinet, but this arrived instead... So, I'm going to roll with it. I was originally planning to do a standard Vibro Champ first, then do a 10 watt version as a head. I'll be using the 15 watt ClassicTone 40-18031 OT, using the 5k primary for a 5881 or EL34. PT is the ClassicTone 40-18109, using the 550VAC secondary SS rectified. Checking fitment of components here... I'm wondering if the closeness of the OT to the cap can is going to be a problem. These are 32+32 cans that I had for my Marshall build. I was going to do 64 for the main filter, 32 for the screens, and 32 for the preamp. Cathode bypass cap for the power tube will be a 100/100.
