I see the Boo Birds of (I know it all) and if I don't like it, it can't possibly work. I would guess the amplifier is working just fine. Looks good and I'm sure you did what you needed to do to get it working. Congratulations on the build. So many people just buy things having no real clue how they work. Nice to see people actually experimenting and doing rather than just buying.

love it!!!! bet it works great!! love that HV supply!! I built my amp with 4X 572/B and 2X 6146B driver tubes. love the bias zinner!! I went with a string of 6A 100 PIV diodes. I wanted taps to get close to class C and AB1 driver stage as well.I also used glow tube (0B2 ??)for screens 6146. ben years I have dual keying relays. driver only, 572-B only or both. 15 years now still going strong. only glow tube never changed.

Adi Ok but... This PA has original sin - the lamp has no cooling! (preferably from below) without it, you will "fry it" in a short time: 0 (( Gl & 73!

FANS ARE SMALL, GU-43 NEEDS 100 CUBOMERS per HOUR..... ГУ-43Б - воздушное 100 м3/ч.

Boris Melkumyan , that's true, sir. At least fit chimney between bottom fan to base plate and base plate to cooling fin will provide sufficient cooling for ICAS with no more than 30% working duty Greetings from Indonesia
