rofl-amp, 5f1 with some tweaks in an old radio

The rofl-amp, audio quality sucks due to the digital camera used recording with.

it's my own take on the 5f1 circuit built into this old 1951 tube radio, the original tube is still doing work in there, PT is original, OT is taken from a similar radio (the original one burned up)

never mind the playing.

I love your amp. How long does it take to build???

@nels7118

i found the old radio, and tore out the guts one night, the soldering of the new components took me about half a day, this was my first build to so i went slow, then half a day of tweaking and biasing. then a few hours to make the controlnob fit snuggly and adding the handle and the external speaker outputs and whatnot i have on the back. So not too long :)

@spinav you could do that... but what he did here was just remove the radio circuitry and switched it for a fender champ circuit.

Nice sound man! Did you have to do a lot of re-wiring? I dont know much about it. Can I basically remove where it gets the signal and insert a jack?

[lukieh]

mate, that sounds fantastic. is the 5f1 same/similar to a champ?

Just a while ago my grandfather told me he can arrange a old radio for me. It would be fun to turn it into amp (I was considering this for 2 years but no old radio was at hand :D).

This is funny, how much people spend for professional amps while they can have good tone by using a bit of imagination.

Here's good exapmple. Very good tone. I would never think it's possible to sound so blue with old radio overdrive (tubes?).
