    A friend of mine had a half gutted Buick radio from about 1938 and asked me to squeeze a circuit into it. So I went with a Princeton Champ 5f2a. I used half a dead reverb tank for the chassis. It’s pretty much a stock build and sounds surprisingly good in a closed back metal cabinet, pretty tight spacing in there. I used an old cast off transformer and B+ is about 50v high, so I may see how it sounds with Zeners. But for now it’s good!

    Aw thanks. I love trying to figure out weird one off builds using what I have on hand.

    Did you build the 5f2a from scratch?

    Yeah, with cast-off parts I had laying around. Only thing new in it are the LEDs I put in and the caps and resistors. It’s all just point to point.

    Thanks for posting. This looks amazing. Also I appreciate the creativity and ingenuity involved with regards to pulling this off and making it happen. Looks like the sort of amp I can imagine Neil young owning. It looks stunning I keep coming back to the pictures.

    Thanks. Will have a video this afternoon if you’re interested... thought the cab would be a problem but it sounds good!

    Here’s a gut shot.

    I wish I had an eye for finding the cast-away stuff that people use to stuff amp chassis into. That one is about as cool as it gets!

    Now that is a really cool little amp conversion. Nice work!

    In this instance I need to ask for a clarification: taxicab or cabinet?

    The parts to complete a prewar Buick taxicab would indeed pose quite a problem, I'd bet.

    Ha! Thank god I’m not going that far. The radio is sheet metal with a closed back. But the sound is OK even with it on.
