0.25 watt PP amp

Well not sure if this should be posted here or with the pedals but this is a low watt push pull amp I have running and am tweaking. I attached some pictures of the little guy next to my coffee mug.

PS Just to add the final amp will have a three position gain switch, gain control, tone control, volume control, speaker out and line out. Inside will be a built in speaker load so the amp can be used with just the line out for an overdrive box. An external in/out footswitch box will need to be used if you need to switch between overdrive and clean but that will keep you from stepping on the amp.

That's awesome! Post samples when it's done .
I see you're using WIMA metal film caps, excellent choice.

cool project..

The first tube amp I built was the "Firefly"

It runs a 12AU7 power section for an output of about 0.75 watts...

Sounds good

the second one

Had parts for three so this is the second amp with a different paint job then the first. Going to look into doing a 1 watt or better SE amp using a 5902 pentode in a box just over twice the size of this one next.
