hello everyone. Ok, i've gotten sick of searching for info on tube amps. Here is my dilemma: I recently purchased a tube amp from an old man. Said amp is basically a chassis from an unknown brand, which was modified (it contains some solid state components, sort of a mic preamp) by someone. There is a sticker inside that says omething like "serviced by *&^^ in "80. Ok, making the story short, ive looked all over the net for some deep info on tube amps, because i have the following questions: 1.- The output transformer has two leads taped off. not in use. What are those? There is no impedance switch or evidence that there ever was one. 2.- There are 3 12axt and two 12at7 tubes, plus a reverb tank. I am guessing that the 12at7s control the reverb. Can i just remove them? 3.- i connected a speaker to the "ext speaker" output, without connecting one to the "speaker" output. Common sense told me that they would be connected in parallel and it would be the same if i used either one, but i got a very weak signal; very little volume. What is the reasoning behind this? 4.- i can't find the exact filter capacitor values. What should i use ar replacements? Anyway, i have several of those questions, i was hoping to find an answer or maybe someone could point in the right direction.... About the tube warehouse, well, it turns out i was searching for some caps, and just to make conversation with the guys at the electronics store, i asked them if by any chance they had some kt66 tubes, or 6l6. Well, the owner tells me "well, actually I do, I have a small warehouse full of old tubes , but it just aint worth the hassle to go there and search around for a single tube. They are leftovers from the tube era. I haven't had a chance to throw them away." Of course, I wasn't gonna tell the man that those tubes may be worth some money . I talked the guy into letting me drive one of his employees to the warehouse and checking out the tubes to see if i can use some of them. I didnt want to look too excited so i told the guys i'd be back next week. So, bottomline is, i'm gonna offer the guy 100 bucks or so to "clean" his warehouse. What king of tubes should I be on the lookout for? Please include brands and , if available, pics.
