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.

This rocks! Can't wait to see how it sounds.
Come on now............in a 1590A!?!?!?!
So good.
That is sh%t hot crazy! Well done man! :o
Awesome! That would look so cute over a 4x12" cabinet. ;D
INSANEBALLS!
:o :o
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."

Absolutely awesome.
You win sir!
You sir won the day. Just fantastic
Fantastic! Epic! Beautiful! Wow!
I quit.
You used an "outie" power jack? Where's the challenge in that??? Haha!!
Amazing work Thomas! Really looking forward to your video.
that is a super cool little amp!

Bahahahaha! A washer on one of the 1/4 inch jacks as well! ok... I probably couldn't fit this all in a 1590b.
Does it have reverb?
In all seriousness, this is fantastic. Incredible use of space?
What do you think of the sound?

:o Wow, that is inspiring
Holy Jesus biscuits!!! That's quite exceptional. I think there's space for an effects loop in there though ;D
Awesome work!
Wow

Hi guys!
Thanks for your kind words!
and I see that some of you have found all my strategies to make it fit, I hope outer jack's aren't cheating haha.
I made the video, hope you like:
I'm playing bad lately, I guess it's the lack of practice, but the amp sounds OK to me.
I cut some bad playing riffs, so don't worry if there are some serious transitions.
Now about the sound...
It has a little too much bass, and with higher volume settings the bass gets very loose.
Maybe decreasing cathode bypass capacitors will help with that.
I also forgot to add the 330pf bypass cap to the volume, but the problem is with full volume.
After this, it's really loud!
Not 15W loud, but loud enough to make everything vibrate on my desk, and make any girlfriend angry.
I was playing it now with my klon clone, and with added trebble it's sounding better.That tamed the bass.
Guess I need to open it again.
Cheers,
Thomas
great work... really epic build, and sounding great too.. well played sir!
This is
AWESOME
I like this (also just bought a carton of PCL84/15DQ8).
What did B+ end up being?
Thanks
