Any information on the sidewinder 350 would be great. Also need the transistor rating specifications. Take a look at it. Looks like it got pretty hot..

The logo "SSS" on the transistors is the manufacturer. Can't even remember the name it stood for, Solid State Systems, or something like that. Wikipedia never heard of them.

They got bought in the early 80s, but I can't remember by whom. S-T Semi, who still uses the "SD" prefix for RF transistors doesn't make that number now.

The online sources only show this number indirectly as a cross reference, but no data for it.

Don't ever remember seeing any info for a Hayden amplifier.

It's an orphan.

Hey Nomad. I found a broken wire at the hi / low switch resistor. Replaced the led's. Fired her up 2 watts swinging 18 pep going in. 50 watt dead key swinging 350 pep out. They call it a 350. I guess she's working properly. Open to suggestions on how many watts it should do.

Looking closer I found that the power and ground wires have been replaced with 8g Chinese wire. Copper clad aluminum sodered together. GALVANIC corrosion. Wire turned to powder. Was doing 350 watts Now months later sitting on the shelf. Just hooked up and low output. Changed the power leads to 8g COPPER. Now has 500 watts out . Beware of the fake products on the market . GO TRUMP. 2020.
