Here's my Tri-Amp 
It can take 10Y, 50, and 300B tubes. 417A drivers, Lundahl Power Transformer, Hammond 1628 (the older, better one) OPT.
It is shown with Hytron VT-25 power tubes, Amperex gold-pins 5842 drivers.

An externally hosted image should be here but it was not working when we last tested it.

Many thanks rdf...
It took a lot af time to put these together... it seems a never ending process, mainly in a country like mine, where the valve art (tube factories, tube inventory etc) was sent to the trash.
It's difficult even to find sockets!!
Anyway, right now, not minding any of these hindrances, I'm doing another tube amp, just to be "stuborn"....
I have some other projects done: as soon as I have time I'll post pictures.

Point to point wiring/circuit build-up (my way....)
Hello
Just wondering if the way I build my circuit boards would be of any help/interest to the DIY tube people...
The support plate is made of fenolic resin (very tough...), 2 mm thick, the tag strips are fixed through holes and copper rivets to it.
After that I solder the rivets heads onto the terminals (tag strips bottom eyelets) to provide good electrical contact and rigidity.
I paint my plates black.
The rest is pure hard work... days and days of it!
