I have these amps, they are fried. Well one is not but it has corroded circuit boards so I am not even going to try to fix it. But they have some heavy duty transformers and power supplies. What can be done ? Should I figure out a switching regulator and make a power supply ? I have one I use for a power supply but it is unregulated so I use a variac with it. I used it to power up an old field radio from WW2 or something my buddy brought over, needed 90 volts. Across the rails it puts out about 120 but I used the variac to cut it down to the voltage the radio called for for the B battery. I forget where we got the filament voltage though. Anyway, I just don't want to see all this in the landfill. The landfills are getting full here. Anyone need like 140 volts at 8 amps for a project ? Don't put that into one of those hydrogen separators, it is likely to blow up in your face. Well, unless you build a big one. Except for audio, I don't see the need for that much voltage and current. What else can use it ? It would be a dandy to watch it charge your cellphone. You'll really know what it's made of. I can build regulators for it, but even to troubleshoot an amp all you need is the old dim bulb tester, and possibly a variac. Use its own power supply. If its own power supply is fried then fix it. I really hate to take this stuff to the scrapyard. Is there ANYTHING out there that needs that type of power supply ? Or should I just scrap it all ? And they don't give all that much, I wonder if it would be worth the gas to get there. I might just throw it out. I really would rather not waste it like that.

The way I see it is, if the trannies are high quality ones made in England or whatever, *don't* scrap 'em. It would be a crime to. On the other hand, if they come from China, just dump them without a second thought. I have a pile of old English trannies here. They're just *fabulous* quality I can't adequately describe it here. I can't bear to scrap them so they'll probably just die with me.

These are mostly HV types suitable for valve (toob) PAs. Like 240V primaries; 4000V secondaries at 100mA or whatever. So just the job for QRO-obsessed hams. :-)

You might give people an idea of where you are located.

We wish. Damn thing will just rust on the outside and not completely disintegrate which leaves us with a bunch of bulk that is useless. If you had a ten pound transformer (many of mine are alot heavier than that) after it rusts you got ten pounds of scrap metal. Saw the copper off and be done with it once the insulation breaks down.

We use lots of kW supplies at the Institute,
in various projects, various voltage ranges.
To keep size and weight down, we use Xantrex
/ Sorenson XFR, XHR types. And 300-watt HPD
types. To keep the cost down, we use eBay.
