Gorilla Guitar Amp

I bought a guitar amp at a yard sale and am trying to find out a bit about it. Any help is appreciated. The model is GG-60. It says it's rated for 120 watts and the speaker says 10 - 65 watts/ 8 ohms.

Before anyone ask, I do not play guitar.

Thanks,

arnie

The 120-watt rating is likely the draw from your AC source, which works out nicely to exactly 1A for a mains fuse. To avoid nuisance blowing, it is likely 1.5A or 2A at most. It is probably a 10-watt or 15-watt output amplifier. Check the output transistors or IC and look that up to determine what wattage you can realistically expect.
Since you don't play guitar, you won't be offended by the tone from your new amplifier. With a 6" speaker, the bass will be really lacking.

These amps were an ongoing joke back in the day, i'm not sure if they still make them. They sound like crap. The ss guitar practice amp has come a long way since the 1980's. A friend of mine made a camcorder video of this amp being played as it was set fire. Funny as all get out.

Thanks all for your comments. I wasn't expecting it to be top of the line but it does have a rather big and impressive speaker. I didn't measure it, but it looks to be about 10", certainly much bigger than 6" From what I've seen, the little ones - the GG-20 have a much smaller speaker.

I figures that for $5 at a yard sale, why not. If I get a good speaker out of it for one of my communications radios, it'll be worth it.

I also wanted an amp that I could experiment with as a modulator for a transmitter. I hear you can turn a 6.3V filament transformer around, feeding the 8 ohms from the amp into the 6.3V winding and use the primary of the transformer to modulate an RF carrier. Again, for a few bucks, it might be a good experiment.

thanks again all for your comments.
