man, you guys are going to think im a real idiot now...
so im looking at my schematic the other night, and i suddenly realize something is very, very wrong with it.
it features 4 tubes.
my radio has 3. none are missing. no empty sockets.
what!? i knew the 442 was based off the schematic for the 444 and the 444-AH, but used some different components, but they dont say anything about removing an entire tube from the chassis! so now im really questioning if i should go with the general guidelines outlined in this post, or if i should go with what the tube manual says with respect to the rectifier tube, at the least, and then go with the general guidelines for the other two, or do i just replace the old multisection with caps of equal value since it did seem to operate fairly well with those values in place...
just for anyones reference, i AM an idiot kid (well, 35 year old kid) who is just learning this stuff. i think the lesson today was that you should go through ALL of your literature before loading up the parts gun and opening fire.
any thoughts or ideas are greatly appreciated! if time permits today ill get a few photos of the radio so maybe someone can tell me if ive misidentified it, or what the heck i did wrong here...
