I got this Fender bass instrument speaker cheap, because it’s missing the burnt amp, so it’s just the 10” Fender (Chinese Jensen) speaker.

I paid $300 for this Ampeg mini bass amp, but it wan’t a great bargain. New ones are $429 with tax & shipping. It had a slightly scratchy pot and sticky switches. I took it all apart and detailed the cabinet and cleaned all the parts and switches. It’s quiet now.

Here it is, all dirty as I received it.

This amplifier is very compact and it has Big heat sinks, and a cooling fan in the back to keep it from burning up.



And it does get warm when you’re playing it loud. It also had big flaps of loose vinyl upholstery inside, curling up and blocking the air vents.
This amp may have been sold because it was shutting itself off during use when the thermal sensors got too hot. This is the same thing that happens with my Yamaha subwoofer when I try to play the bass guitar through it.
Anyhow I got those all trimmed down and glued down good, and I tested everything out OK and put it all back together.
It took me a little while to figure out what a true marvel of modern engineering this amplifier is.
Notice how this amplifier will put out up to 200 Watts! That’s a lot of watts from those tiny transistors folks.

Even more amazing is the fact that, in spite of shedding all this heat into the atmosphere, this amp only requires a mere 150 Watts of input power!

Ampeg has literally invented the perpetual motion machine, which is pumping out more electrons than I put into it!
That’s all BS of course. This equipment does not quite fall into the umbrella of professional sound gear. They’re supposed to tell you the truth about power consumption and output and efficiencies.
But consumer goods like this have been playing games with the numbers for 50 years.
The input power requirements for this amplifier are listed at 150 W RMS power.
But the output may be rated in something called “peak music power”. What this means is that an amplifier taking in 150 W continuously can put out more than 150 for brief spurts, without overheating.
But the truth is that an amplifier putting out 200 W RMS continuous power is going to be at least twice as big as my Ampeg.
