I joined this forum in the hopes that I can get some assistance....
So I have an Ampro 20 Premiere that my Dad bought for me in 2011 to replace our Ampro that was damaged from a flood. He bought it on ebay and was told that it was fully functional. We never had the time to try it out and a few months later my Dad became ill and passed in Jan 2012. Anyways, all this time later, I finally got it out. Mind you that it sat in the garage for 10 yrs. I have ordered a service manual and currently awaiting for its arrival. I cleaned it up, got all the dust off of it and gave it some lubrication. Opened it up and it has obviously been worked on before. There is what appears to be lamp cord now running to the exciter bulb. Also, someone folded electrical tape over the insulation on the bulb over the control panel. It does power on. Seems to run very smooth and the lamp lights. That is as far as I dare go. Scared to turn on amp. Pretty sure it is not going to work. I had the tubes out and since no way to test them, will probably get all new ones. One tube, a 6v6 I believe, was pretty black at the top and another one the glass moved slightly up and down. It is probably shot. My main concern is in the picture. On what I believe is called the small board, there is a blackened area under / besides a resistor. Any idea what could have got hot enough to do that? Is the resistor bad? No other apparent damage anywhere. Suggestions greatly appreciated on plan of action.
