Nice looking amp! Ilike the woodwork, on teh base.
When I was first experimenting with using 6AV5GAs in a GSG, I started with teh 6AX5 rectifier, and found that I needed a bit more B+ voltage, and current capability, so I started out with soldering UF4007s into an octal base. That made a bit too much B+ voltage, for my needs, so I then connected a 50 ohm, 5W WW resistor in series (on the anode end) with each of the 4007s, and that worked out very well, and later I translated that design in to another 6AV5GA build, which is one of my favorite DIY builds, with an amazingly good sound quality.
I used to have a set of the exact same Barzilay speaker cabs, with the same grilles. , and the center "console" which fit in between, and the wood grain was "matched" so that when they were properly arranged, the wood grain on the cabs and console tops was neatly matched up, and looked like one long continuous piece of wood. . Unfortunately they took some water damage, after having stood in about 1.5 inches of water in the finished off part of my cellar in NH, and I got rid of them before I moved south to NC Friend of mine took them, and he said he would try to repair them, though that may be a tall order. He has much better woodworking abilities than do I.
The manufacturing date for the Barzilay cabs was around 1967-68.
I had some 15 inch Altec Lansing 411A drivers in the cabs, and Altec 811A / 806-8A 800 Hz horns on the tops, and I built the crossover / divider units into the back panels of the cabs. It was a nice setup until they got "drowned" around March of 2001. The speakers survived OK, I later traded the 411s, and kept the horns and dividing units for my Karlsons, which are with me in NC presently.
