I really need some help, i checked all my connections reheated all my solder joints tryed 3 diffrent ground schemes and still nothing. no sound at all. i touched the input jack terminals by mistake and got a buzzing sound i thought came from the speaker but it was comming from my first 6v6 the one nearest the rectifire tube, also when it buzzed there was a blue flash inside the tube. any one have any ideas? all the voltages seem right.
Thank you

I would make sure the speaker works by itself, then I would explore the wiring from the output transformer to the speaker. It sounds like the speaker or its wiring might be open. That is consistent with flashing tubes. WHen tube amps do not have a speaker load, trying to play or make other sounds through it - including just hum - causes tremendous voltage spikes. That can flash your tube. Also, when no speaker is connected, you can hear things you never would otherwise: transformers and tubes can "sing." They make sounds from the signal going throught them.

It is possible something was damaged, but even so, if the speaker is wired to it right, you ought to get some sort of sound.

Start there.

Ok, I get the bonehead of the year award!!! The amp works great now.
All of my jacks were wired wrong I'm not used to using switching jacks and i had the wires off the board going to the switch insted of the tip.
Now i just have to find that neil young tone
Thanks for your help
