Got an amp on my desk.
Haven't plugged it in yet.
Has 3 prong cord already
Speaker cone us real flimsy aND sounds like it may be rubbing when I manually excurse the cone.
Ive Never worked with a 6X4 tube before.
The model number is on the back. Here are two schematics for the Silvertone 1482.
It's a guitar amp, 8 ohm alnico speaker. The gray basket weave vinyl was classy.
My first store bought amps was a Silvertone. It used to sound very special when pushed. Something about the tone of those old amps. I then used a side-by-side 215 bass amp that had a head that clipped onto the top.
Coolio... gonna start checking it out this week.
A cursory check reveals they date from 1961 to 1968.
Appears to like a tweed deluxe without NFB.
And you can jumper the channels
It's a nice little amp for sure.
There was a tremolo foot switch. Just a simple switch, most replacements would work.
I'd change the speaker. The cones on a lot of those older Fisher ones that I've had would turn to dust with time.
the 2 - 6V6 power tubes equal about 15 watts (like a Fender Princeton) with a better speaker, this should be a really nice guitar amp!
Like with all old amps, you are probably looking at having to replace all of the capacitors.
looking at 3 schematics, noting the variations now. some have 330k grid stoppers shown (on the 6v6s) and some dont, and different voltage measurements here and there. may pull the chassis after lunch.. workload depending. no idea yet on the service history
being pre-emptive, im trying to find a multi cap-in-can (20/10/5 uf @ 450v) . such low values are being a little difficult to source. I can find 20/20/20 easily enough, but im not sure if the power supply is able to handle the extra 20uf, the 6x4 is pretty small
It could be that the e-caps are shot. If not, try the amp and get to know it. Guitar amps often have less capacitance in the power supply because this promotes an earlier onset of distortion which can be desirable in a guitar amp. Boosting the caps can change the character or the amp. On the other hand, if it's too distorted, maybe upping the capacitance would be a good thing. Something that is best to experiment with but there are some serious power supply limitations. Look at the capacity of the 6X4. The deluxe uses a 5Y3 rectifier which can provide just over twice as much current. The 5Y3 differs from the 6X4 in that it uses a 5V heater, this requires a separate power transformer tap. The 6X4 uses a 6.3 heater, same tap as the other tubes.
I'm not a fan of some cap cans such as the FP ones used in a lot of amps. You can fit separate caps under the chassis rather than use the cap can. Another alternative is to hollow out the existing can and put a cap inside or leave the can mounted for looks but don't use it.
It could be that the earlier revision had an issue that needed to be addressed.
I love those old Silvertones, my first band had two Silvertone Twin Twelves for 2 guitars, bass and three microphones!
The local GC had a Twin Twelve in the "crank it up" room last time I was in. Totally being ignored, the amp was still in the piggy back spot. They were asking 399,I think. I almost just did it. But na, I don't need more stuff. Might still be there, I know a Peavey deuce 2x12 sat there for almost a year at 199. (?!)
Yep, it's a 1482. Great sounding amp (but not cab). I put mine in a head Box and use it for recording. Sounds great with an SVT210AV for a dirty sound blended with a clean DI. The output transformer has 4 and 8 ohm taps available, so it will drive two 210's. I highly recommend it.
It's surprising how good some guitar amps can sound with the right bass cab with a bass guitar.
That is seriously awesome.
My guitarist has that same amp. It's awesome.
BTW like the Silvertone guitars of the era, those amps were made by Danelectro.
