Hello, my name is Matt, and I'm new to the forum. I just picked up a pro tube 50 from a guy on craigslist. The amp worked seemingly fine when I tried it out at his house, got it back to my apartment and the amp played for about 6 minutes, then I shut it down because it was late. The next day I went to play the amp, and I got nothing. The guy told me that it needed new power amp tubes, so I put in tubes, replaced the fuses, and I still have nothing. I don not hear anything coming out of my cabinet. I have the amp set to 110v (in the U.S.), I have the output selctor set to 16 ohms, and run one speaker cable out to the 16 ohm input of my marshall 4x12(which came with the head). Any thoughts on why the amp would stop working over night? and not work with new tubes? Please give me any help you can. This is a terrific forum.
