Recently I had occasion to have to rebuild THREE power supply units ( located
under the chassis) of the Commander line of amps. Two HF2500’s and one
VHF2000. Both use the same power supply board. Unfortunately all 3 boards
were damaged by heat and the traces flaked off the boards in many spots. The
traces that didn’t lift normally did when tried to unsolder and resolder new
parts. The old boards are basically unsalvageable to rebuild. The boards are
obviously old technology. They are a one time board as far as I’m concerned!
As usual confronted with the need, I’ve developed a brand new board using new
technology on boards with masking etc. I need these boards to professionally
rebuild the power supplies in these amps. I don’t trust Gerry rigging these
old decrepit boards. The whole amplifier RF deck must be removed from the amp
chassis to get to the power supply. You don’t want to go back on after using
band-aid methods on the old boards. These amps are terrific amps and can go
another 35 years with the breath of life from an all new board. Hopefully
within the next month I will have these boards ready. I ordered extra for my
supply for further repairs and for those who would like to attempt their own
replacement I will have a limited supply I’ll be offering them fully assembled
and ready to install The price is unknown at the moment until I can fully asses
the expenditure. If interested I’ll take orders on a FCFS basis. I’m going to
be installing one in my own personal amp as well. I have my own transformer for
testing so if you don’t feel confident in doing the replacement yourself I only
need the RF deck and can do it here. It’s a shame to see these good old amps
sidelined for lack of parts. Thanks for reading Lou
