Single PCL84 amplifier build

[thomasha]

Hi guys,

just finished a one tube amplifier! It runs with a 12V adapter, and has a MAX1771 SMPS for the HV;

I built it in a 1590a box, with both sides etched in an old vintage style pattern.

This build was quite difficult, mainly because there is no board for the amplifir itself since everything is soldered between the potentiometer, the input jack and the tube socket.

I had to make the SMPS smaller too, so some capacitors are not soldered to the little board.

I would say it has something like 0.5W but has a nice overdrive!

Hope you like it, soon I will make a video !

Hi guys,

inspired by the TMC1 I tried to go a little furter decreasing output power and cost.

Here I present this typical one tube amplifier, that works with a SMPS instead of a big expensive PT.

The output transformer is also a cheap 220/6V transformer that I had laying around.









Cheers, Thomas

INSANEBALLS!

When scientists discover Hammerspace in real life, this kind of 1590A usage will be involved as study subjects.

Amazing build. As Elaine would say on Seinfield. "I'm speechless! I am without speech."

You used an "outie" power jack? Where's the challenge in that??? Haha!!

Amazing work Thomas! Really looking forward to your video.
