Default Need help identifying this amp...

I may have aquired an old tube amp. I need to talk to the person that owns it and see if he wants to keep it or not. Anywho, the volume pot/power switch is scratchy and the two input jacks are all rusty and there's a nest of some sort (most likely mice) sitting under the speaker. In other words, it needs some help.

The only things I can tell you guys about it are that it has an Ampeg logo on it, the afore mentioned pot/switch combo and two jacks, and an 8-inch speaker. That's all I can tell without pulling it completely apart.

Oh, yes, and this time I took a picture... not that there's much to look at...

So it's a bass(guitar) cab. Could you post pics of the internals?

The owner should be here within the hour. Taking a closer look at it, the control panel is glued and nailed in place. I'm starting to have this sinking suspicion that this amp underwent "modding" or "refurbishing" or some other unnerving process.... more to come later, I hope. On the upside, this could be an interesting fixer-upper....

Given that somebody thinks it has scratchy pots, it seems to work? That is a plus right there.

The next step is to see if it is on of those transformerless wonders from that era. By style, it looks from the 60's, and with an 8" speaker, and one volume knob, it does look like an el-cheapo. Not great.

Peek under the hood and look for transformers. Hopefully two. They look like bricks made out of laminations of steel. Or, check out the tube numbers. Tube numbers that start with 30's or 50's are a bad sign, and means you have merely a carcass for a new project.

Rusty jacks, and mouse nests are no worry. Jacks are cheap and easy to replace, and I assume the mice are dead. Scratchy pots (I see only one pot) could be fixed when you replace all the caps (2, 3, 4?)- which would be mandatory in any scenario.

Oh, and check the speaker cone for damage from the mice or other creatures like humans.

So, dig further. Could be a nice amp with not much trouble. Could be just a wooden box with a 60's vibe. Depends on what you see inside.

Worst fears confirmed. One transformer. several capacitors and two transistors.

You can always make an external speaker out of it... Better than nothing, I guess.

Buy it for $10. Live with the rusty jacks, replace the few caps. You'll have a nice practice amp. I have a similar one, a G-18. Not great, certainly, but not horrible. One day you can give it to your kid or the kid of a friend and be a hero.
