Hi everyone,

So after so many years one of the two voltage regs died and I figured what the heck, we now have the Internet so I can get a spare pair.

Well the Chinese want between $60 and $80 for a pair:

I'm a bit stumped. This one was made in June 1981 by Lockheed Martin (correct me if I am wrong here) so how can be so expensive to replace a dead reg on an oldie but goodie power supply?

Any suggestions for sourcing LAS parts out here?

Thanks

Interweb search turns up crap. Please describe what this critter is supposed to do and we can probably find something that fits. It's a 1.5 amp Vreg in a TO-3, but is it fixed or adjustable voltage?

Here ya' go. 13.8 volts. Pinouts to be discovered...

The answer to your other question is economic. After a part goes EOL (End of Life), gray market vendors snap up the remaining inventory hoping to monetize their investment off of a purchasing agent that needs stock and has no time to screw around looking for parts. They could care less about a person such as yourself who needs one to a handful. You are not even on their radar.
