Otherwise, there's not a lot in there - it's a pretty simple circuit. Problems with one of those would be the worst thing that could happen, I think. There are three transformers on this amp - power, phase inverter, output. I do that without any other provocation.Ĭan you describe "static" a little more? Is it a buzzing sound, scratch like a pot static, a knocking sound, or something else? I also check to make sure wires and cables - especially speaker cables - are securely soldered or otherwise connected if they're not soldered. I always start out by cleaning pots, tube sockets, and input and speaker jacks with a good tuner cleaner/lubricant like Caig DeOxit. Do you know how to check for that? I don't want to tell you to go inside and monkey around unless you know how to do that properly. When you go back to the old room, does the problem go away? I have one AC outlet in my house that has inverted polarity - I discovered it recently and I need to fix it. Really - I should stop yacking about these until I get another. But I first had to go in and clean these amps up to get what I wanted. I put an extension nut on my Junior for a while. But honestly - I just loved these with a P-90. Sounded great with a lap steel too - I had an old Oahu Tonemaster then. Try it with a Junior or some other solidbody with a P-90. I find a hair of compression often helps keep these little amps from bottoming out when cranking them. But these amps also took a simple clean boost just great - either a straight clean preamp or perhaps a compressor with some gain & not much compression. Some older 50s NOS 12AX7A tubes worked well also. The very raw-sounding and midrangy Chinese 12AX7A tubes that Ruby used to supply 10+ years ago sounded good. I used the highest gain tube I could find. There's not a lot of gain in the preamp section of these. I think I had a Celestion Vintage 30 in one of mine. Once I gave them a good going over, replaced electrolytics, and possibly subbed a good-quality, high-efficiency speaker with some balls, mine were really nice. Like Dan, I wouldn't put a Torres mod on anything, but I think I'd leave this amp stock anyway. It should be louder and ballsier than a Champ, maintain some of that silverface sparkle, but have more midrangey tube distortion from the cathode bias. Properly set up, they should be, more or less, like a cross between a silverface Champ and a tweed Deluxe. Two cathode-biased tubes run push-pull with a transformer phase-inverter, it's a strange beast. These are different than anything else made by Fender during the 70s. Those are some primitive-sounding tubes, used on some early amps - I think some of the early, small Gibsons used them. ![]() I like both versions, but you're right - the 6AQ5 version definitely has more balls. One of the best little amps I've ever played through for just plain balls with definition. ![]() I've had both kinds, and I wish I had one now.
