DC tube radio busking amp update

i added a 3 watt preamp its much louder now. in these videos it also has a 8" speaker in a cardboard mr coffee box in addition to the 4" radio speaker. i need a pot on the pre amp i think it sounds better with 15 volts going through it not 9. at present its 105 volts of battery only power but i can get it up to 111 volts DC. be careful the videos are very loud, there is no effects at all just a 365 C and a pro harp in G.

Billy, that thing sounds wild! I love the overtones from the distortion, just sounds huge.
