Good morning Mossberg Owners.
This 1980 Realistic was their first high powered Dolby stereo receiver. I don’t know what the actual power output is but the view meters go up to 200 W each channel.

It has some heavy duty hardware but some of the capacitors are bad.
But not as bad as this computer power supply that I was trying to re-purpose.
View attachment 24738 Look at those blown out relics.
This is my temporary shed stereo set up. There’s two more of those speakers up in the rafters.

It runs off an old computer power supply from which I have disabled the 3.3 V and 5 V circuits leaving just a 12 V output, the “power on” switch lead, and the leads for some status LEDs (not installed yet.)
Tthis PSU is bigger more powerful and more modern than the one I was going to use & fortunately this one still has good components throughout. The smaller one has taken too many voltage spikes over the years.
Also there was a period of time when electronic equipment around the world suffered from mass production of horrible Chinese “fake” capacitors.
lots of output transistors shorter than burned when these capacitors decided to get tired prematurely.
This old Sanyo Quad was my former shed stereo, but it needs some work now and it’s not worth fixing. Here I am cutting the wires off the back so I can wire up the back channel speakers to the (“120 watt” LOL) car stereo which I am using now.
View attachment 24739 The drivers in those old Sanyo boxes were as primitive as it gets.
I replaced them with some more modern drivers and reinforced the boxes.
I lost all of my classic stereo gear and the custom speakers I built in the divorce 30 years ago. I never spent the money to replace it with similar equipment.
Right now I have a Pioneer elite 7.1, Blasting out 700 W in theory…
There are 17 speaker cabinets hooked to it, Plus a 300 W dual cone active subwoofer.
1000 watt audio (theoretically) . . . I would’ve been totally freaked out by this back in the 1970s.
BTW The subwoofer is totally unnecessary unless you want to play those earthquake movies.
I wish the elite receiver had an accessible parametric equalizer, but it just has a lot of presets and computer optimized formats.
You just flip through the buttons until you find the one that sounds the best LOL
