Re: [Amps] LK-800A

Sorry I don't have exact details, but . . . a fellow named Bill has an 
amplifier repair company named "Alpha", something.

It's in 4-land.

Bill was production manager for Amp Supply/International Amp when the 
LK-800X was being built.

Google should find the company.

Good luck,

Barrie, W7ALW
