Wow you're really talented. I wish I could do that.

Looks amazing,wish I lived in a house tidy enough , it'd have to be covered, wouldn't look so good covered in dog hair and dust.beutiful work tho.

EXELENTE !!!

What beautiful details! You don't even have to turn on the power! Listen to music on the player. Які гарні деталі! Можна навіть не вмикати електроживлення! Музику послухати на програвачі. Какие красивые детальки! Можно даже не включать питание! Музыку послушать на плеере.

This is beautiful. Great work.

AIM9G last of the tubes in the Sidewinder air to air. The AIM9H first of the OpAmps Sidewinder, using cordwood modules. In 1974.

Do you have a schematic for the psu. The mark iv is different from what you built. St70 is also different. What transformer did you use for the psu. The only transformers I could find on piemme Electra was the pa-60 and a-470.

Really satisfying to watch. What is the planning process that moves you from say the circuit diagram to the architecture of the turret board and the components in situ?

you have to plan the assembly of the components through the wiring diagram

looks like a nice amp, I build my own Tube amps and other stuff from the ground up and have a whole system using pretty much only tubes. But we don´t even get to see your amp lit up and playing?

oddly satisfying

Great video, thanks. What caps did you use in the power supply?

Bravo, c'est très joli. Par contre normalement le transformateur d'alimentation ne doit pas avoir ses tôles orientées dans le même plan que celles des transformateurs de sortie mais je peux me tromper. Comment sont raccordées les liaisons vers les HP, secteur etc?

Its about how its wound, it may look in the same magnetic plane but its unlikely.

Looks a bit like Dynaco’s legendary solid state “Universal Tiger”. I like the raised tube sockets and floating PCB, that maintain point-to-point wiring. But what happens when the tubes inevitably burn out. In what countries are tubes still being manufactured?

Some tubes aren't being made any more and of course NOS ones are now $$$$ but most tubes are still made somewhere, Russia, Eastern Europe, and China mainly but Western Electric just started making the giant 300B again in the US with plans to start making some pre-amp tubes soon.

The Universal Tiger was Dan Meyers design ( Southwest Technical Products ) I built one in high school in 1972. Still have it. It just blew away my Crown D150a . The McIntosh clinic guy said it looks crude but works as well as any McIntosh SS amp of the same vintage.

Wow, that is hot. And nice transformers by the way. Is it possible to get the whole kit online?

hi , i have only the pcb

Can this amp be compared to be par with audiophile amps, if can be, then with what model? Also, is this kit shipped to any country? Thanks.

@pcbaudio

10 ай бұрын

to compare it you have to listen to it yourself but I think it's impossible, the only way is that you have to build it. No kit is available but only the bare boards with turrets. Thank you from pcb-audio.com

I did. This stuff 60 years ago

Listened these type of amps in the 70's. Nothing compares to them. Thought I would be able to build one like this but there is no enough info. Jumps from setting one channel to a whole power supply finished

Wrong transformer mounting... decouple the power transformer flux from the output transformers by rotating 90degs.

So you'll have an amp sitting in your home with several hundred volts exposed all over it just waiting for someone to mistakenly touch it?
