JBL PB10 Help - Transformer getting hot

105°F, The longer it is on - the temp continues to rise. However, I checked the amperage-draw at the power cord, very, very, low.
105 F?
That's ALL?
That's nothing, why worry about it?
As long as the AC line is fused.

I've got a 1963 console stereo (18 tubes) that has a power transformer that COOKS after being on a while.
You can't even put a hand on it, you'd be singed! (likely over 140 degrees)
It's lasted all these DECADES and still going strong.
 
I know that may have been confusing but one day it got so hot one day I couldn't hold it and the bass had faded away by then.
Ok the mini-fan ploy is keeping it cool, I can limp along with for a while, maybe I'll find a parts doner PB10.
I did try 3 different power amps, none had the same characteristics as the original.

Thanks for all the help!
 
What could possibly go wrong?

I found some more info, these powered-subs have a terrible reputation: last only 3-4 years, 54watt amp, power-caps blow, make a big mess.

Now you've been educated as to what I've had to deal with in the repair shop for decades.
Plain garbage made to last 'only' shortly past their warranty period. - AKA built-in short lifespan.

I've told my customers: Well, welcome to the 'new age' of products, the (greedy) manufacturers don't care about you, they've already gotten your money. - go buy another one to keep them in business.
