I finally dug through the boxes today to see just exactly what I have. Some were not even opened yet.
06) 5Y3 GT usa
01) 5U4GB usa
02) 6n3c (Russian 6L6)
05) 6v6 GT usa
07) 6n6c (Russian 6v6)
18) 6h2n (Russian 12AX7)
04) 6SN7 GTB usa
01) 6SL7 tung sol
01) 6SC7 usa
02) 6SJ7 usa
01) 6AV6 7-pin
01) magic eye
03) 350-0-350 80ma PT with 6.3 and 5.0
03) 325-0-325 50ma PT with 6.3 and 5.0
My Boothill 5e3 is already assembled and this is what is left from my buying spree.
I'm thinkin' maybe a 5C1, 5C3, 5F1, and another 5E3
I have a big sheet of garolite, a bunch of brass eyelets and a boatload of octal and 9-pin sockets, plus a bunch of 1meg pots.

Only the Russian ones are worth keeping.
Send the rest to me.
I use them for Cristmas decorations.

Amp 1. 5C2 Princeton 6SC7 and a 6V6 GT - Octal
Amp 2. 5F1 with a 6h2n and a 6n6c - The Champsky (6h2n is not direct replacement for 12ax7)
Amp 3. 5C3 with a 6SL7 and 6SN7 and 2) 6V6GT - Octal
Amp 4. 5E3 with 2) 6h2n and 2) 6V6GT (6h2n is not direct replacement for 12ax7)
Amp 5. Still got the Hammonator to complete, but that's going to be more of a challenge.
This tube stuff makes me crazy.
(6h2n is not direct replacement for 12ax7) have to add this so when some amp tech wannabe - like me - googels "6h2n" and sees this thread, they might think it is a direct replacement for the 12ax7. it will work great but, the pins 4,5, and 9 get wired a little different.

If those USA tubes are name brand and NOS you have enough there to both keep some for amp builds and finance the purchase of the other necessary components. Especially the 6V6GTs, if RCA blackplates they are worth serious money.
Personally I love octals like the 6sl7, their only downside is the filaments are not humbucking like in a 12ax7 so are prone to noise.
The 350-0-350 80ma PT should easily do a 5e3 type build, voltages are a bit high but will brown nicely with the low current rating.
The 50 ma PTs will do nice single ended builds.

I printed out my layout sheets and schematics and a couple of turret board blanks and opened up my big flat box of garolite.
The two turret board templates have been printed and spray mounted onto a sheet of index stock. then cut out.
Next I scribed a couple of lines and fired up the jigsaw. I remember my bandsaw didn't fair so well against the garolite last time.
Next I make little indentations in the garolite. I'll drill the holes with my handheld drill.
The 5F1 board has it's brass eyelets in place.
The 5C3 eyelets are set in place.
