I just wanted to mention my little Hellhound. I just recieved new tubes from TheTubeStore.com and wow! My little amp sounds really good now! It uses 2 x 6L6 power tubes and 3 x 12ax7 (plus a 4th one for the reverb).

It sounded a little weak and rattly before the tube change. I'll have to record something for you guys - it sounds nice and tight now.

These amps usually go for 400-500 bucks on eBay. They are no longer in production. It's a great little tube amp that is well worth that money.
