Well, relatively easily. It's like making a CBG, but simpler.Photo is at the end of this article. Ted asked me to re-post this here for the Amp group. Nicetameecha! :D CBG players often wish…Continue

I'm planning to make some mini amps out of old tins and I've been looking at kits based around the LM386 chip. I don't want to buy them from the US or China (I'm in the UK) as I'll have to wait a…Continue

Resistor Question:
I have a 4ohm speaker and an 8 ohm amp. Planning on adding a 4ohm resistor to the speaker to equalize. Is it best to put the resister on the red or black lead?

The volume is moderated for the video, it goes surprisingly loud
Awesome find Sam, but I can't tell you what you have. Some thoughts:
It doesn't look like there is a fuse - I would plug it into a power strip with a circuit breaker to isolate it from your home wiring to avoid it blowing the mains circuit.
It appears that the 4 black 'knobs' (lugs) are your input and outputs. If it works, you can easily replace them with two ¼" jacks.
My guess is that the two lugs by the Leviton switch are the input.
My guess is that on the output side, the outside lug is positive - because the capacitors bleed to ground
I would try it!
Good luck!!
OK...so I found this vintage amp of some kind at a garage sale.... I am clueless, but would like to use is as a low wattage head for a prim head/cabinet unit.
Can someone tell me 1) what do I have? 2) is it worth replacing the tube? 3) will I die if I plug it in? The cord looks like vintage lamp cord in good repair.
I don't mind a little learn by doing, but just don't want to screw things up right off the start... any and all help appreciated.
hello,thought i might ought to be here,getting an amp collection now so i will get a few pics up to show some of them.

You did good on this amp set up. I will go get one from HF and then locate a speaker from some where. Really sounds great, both the amp and the 4 string
Here's a youtube of the CBAmp based on the innards of a $ 6.99 Harbor Freight "Mini Handheld Megaphone"... Added a 4 ohm speaker salvaged from a Rocktron practice amp and a jack soldered to the leads that originally went to the megaphone's mic element.
For what it is, I think it sounds pretty good. Makes a nice companion to the CBG in the vid. This was recorded on my laptop using the onboard mic and camera. No pedals, effects or processing to enhance the sound. Pretty good for $ 7... eh?
the best,
Wichita Sam
