Amp Not Working
Agree with the above that you may have popped a fuse. Unplug the amp from the wall and then check the fuse(s). There should be a very fine wire running from end to end with no breaks in it. Being that the amp has sat for 10 years, the electrolytic capacitors have probably gone bad. They made be able to be reformed with a variac, a decent amp tech should be able to perform this for you. If it doesn't pass after bringing it up on a variac, the caps will need to be replaced. Shouldn't be too expensive. Less than $100. Caps have a useful life of about 10-15 years and if these are the original caps from the 1960s they're due to be replaced. Probably would be a good thing to have it checked out if you planning on playing it regularly. Have the pots cleaned (don't use WD-40), check the power cord (I think it best to replace it with a modern three wire cord) and look for any bad solder joints that could use a touch up. If you are going to play at loud volumes, I would recommend getting a new speaker and put it in. The new speaker will be able to handle the power better and you won't blow the original. Keep the original speaker in the box that the new speaker came in and case you want to sell the amp, you'll be able to sell it as all original. Same with the caps and tubes if they end up getting replaced. Good luck.
