I picked up this old tube radio a few years back, thinking i'd make an amp from it, but after tinkering for days, i could only get static from the radio, so i put it aside, and forgot about it, yesterday while having a clean out, i decided to throw it out, but decided to try it one more time, this time in my carport, Hola! clear as a bell radio, my tin shed had been the problem all along, 2 hrs later, after adding a 3 way switch and a jack, i had a nice valve amp, but a little quiet, added an inline low impedence mic amplifier and it's awesome, then added a boost pedal and even awesomerer, but the speaker won't last with the boost up high, very happy.

Thanks guys, but no great credit to me, i just added a few wires, pretty simple job
that is like a battle sip of cool, Darryl!
very nice.,.,reminds me of grandmas nightstand.,.,
Great, i like this!
Dave,Looking at the pot from the rear, with tags facing down, left should be the input, middle output, and right ground, i used the pot ground on mine to the jack, also i didn't mention earlier, that the middle, [switched common] lug from the switch went to the input on the pot
Dave, i just disconnected the input wire to the volume pot, patched in a 3 way,[that's all i had handy] with signal from radio on one leg, and signal from jack to the other, and ground from jack to ground on pot, i'm not 100% sure whether that is the best option, as the amp volume was about 1/2 the radio volume, and it may have missed some circuitry needed from the radio, however, the simple in line impedance matching amplifier that i use on my "induction" type pups fixed the issue very well, so i,m reasonably sure that it was just an impedance miss match, then when i added the pedal it really screams
Nicely done!
