I love the indicator tubes.
Do you you have a schematic? What is the output of the amp?

Thanks, i really am proud of my first project.
Schematics I used are from lighthouse electric:

Low Power SE Vacuum Tube Power Amp

I deleted the neg feedback loop from the output to the input.
The indicator tubes are not too hard to get going.
If you are going to try it just shoot mer an email.

As for output, about 3 watts in triode mode and peaking at 5 in ultralinear.
Nice little listining amp, I use it in my office at work.

And again, thanks!

Hi Azazello
I like small amplifiers too.

Here are a couple more pics of the inside

Click the image to open in full size.

All components to the E80CC dual triode input stage
bar the coupling caps and the feedback resistors ( the ones with the red insulated leads)
had to be stood on end, in order to get them into
the limited space available.
They are terminated at the top onto an up and over earth bar
taken from the input star.

The completed inside is shown below

This pic below, gives an idea of the size of the amplifier

Great job!
I love the overkill OPTX. The rh really sings with good Ptx.
