[TowerTalk] Pro Search controller

[Barrie Smith]

I have a Ham-4 rotator controller called the "Pro Search", which has 
completely bitten the dust.

I don't believe that the failure was caused by lightening, nor any other 
catastrophic event.  The interior looks clean, with no burn marks or other 
obvious defects.  The one fuse, and one circuit breaker check okay.

Since it's completely solid-state, and I have no schematic, it's not likely 
that I will be able to repair it.

I bought the unit at least 15 years ago from Hy-Gain, but they no longer 
offer service or support.

Any ideas as to who may be able to repair this thing?

TIA,
