ECL86 tube amp in metal lunchbox

[thomasha]

Hi, I made a video of this little amp.
It's a single ECL86, with a real PT, salvaged from an old dual amp.
Recently I saw a philco signal tester on ebay, but couldn't buy it. In the end it gave me this design idea.
this one is the original one, couldn't find more pics.


And my version:



The circuit is very basic, would benefit from some tone shaping.
And a video>

That looks beautiful. Really really cool.  I like the sound too, very nice demo.
After watching your video I'm wondering is the Jewel light strobing because of the camera?  Must be an LED indicator then?  Once again, great build, well done

Awesome!

Maybe mount a piezo to the back panel for some authentic plate reverb?!

It vibrates much faster than a reverb! Don't think that would work!
If it were bigger it could sound like a thunderstorm, but in this size it's just anoying.
I bought some rubber dampers and in contact with the PT they force the back plate in position, so it vibrates slower now, and produces less noise when overdriven. Now maybe I could give the reverb idea a try.
