I have a 13.8vdc Drake PS7 for sale. It is rated at 25a continuous as the Drake TR7 was designed to run full power RTTY (100w) radio. I bought this with a Drake TR7 about 10 years ago and the PS did not work as advertised. I found that someone did a hack repair by replacing all 4 of the 2n5301 (200w) pass transistors with 2n3055 (115w) transistors. Plus the driver transistor TIP31 was cooked also. I rebuilt this about 4 years ago and have now decided to do some spring cleaning. This PS does have the optional cooling fan installed.

Asking $125.

If you know anyone who might be interested please pass this along to me.
