I just picked up a BEZ T3A-3 from a member of another forum. Should be here later next week.
The original Chinese tubes have all been replaced. Here is the tube line up as it's being delivered.
2A3 tubes are now Electro Harmonix.
6K7 tubes have been replaced with Mullard EF37A tubes. These are the ones painted red and have a top cap.
The 5Z3PAT rectifier tube has been replaced with a Westinghouse 5U4G.
From what I gather, these are hand built using point to point wiring and uses a lot of surplus military components.
Does anyone have any info on this amp and possibly a schematic? I'm not sure if anything was done to the underside of this amp. I believe that this is an early model and I'm sure changes were made along the way.
My only other SE amp in the house is a Dennis Had KT66. Sounds great with some old Mullard EL34 tubes I picked up at a yard sale.
Any help would be appreciated.
