Hi guy! Ok here is the shakedown...I just acquired a "sears" silvertone model 1484 head from a friend at work who just recently had a family member pass away. Upon inspection of the amp it would not emit any sound, All the valves would warmup nice and bright so I proceeded so flipped it over to get a look at the inside of the chassis.... a couple of wires were unsoldered from the output transformer and soldered in places that I just dont even understand the reasoning behind lol mainly being the ohm taps and the speaker jack(resolved except two ot wires). As of the moment I have gone through and measured most the carbon comp resistors and will be replacing the electrolytic caps very soon and honestly everything else is checking out except for 3 wires that I honestly have no idea were they go or what they do. I am still very new to tube amp circuits and schematics still look like gibberish to me so I wanted to ask if anyone is up to the task wouldn't mind helping me find where these mystery wires might be placed??? and see if I can perhaps get something from the amp before I start spending money on tubes and checking the output transformer and such. Thanks guys! and I most defiantly would appreciate it!
The first pic is of the two wires from the output transformer that I do not know of, the second being a red wire that was snipped for some reason and the third the schematic and fourth just for reference.
I know they're are so many factors that can go into this stuff like tubes considering they are all the original RCA tubes and the ot might be blown being I also heard they like to kill them but I know without a doubt before those are suspect incorrect wiring needs to be fixed first, Thank you so much guys!!-Jacob
