[Amps] Ameritron AL-800

[Robert W5AJ]

 Doug,

I had several 3cx800 up for sale ->  I think 400 or 450$ each
healthy tubes too.

NO TAKERS.

73 Robert W5AJ

Keep eye on swap.qth.com    and eham.net for the tubes.

I have box of 3-1000 and 4-1000 tubes too but my tester hasn't been fired
up in a LONG time!
