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
