Just some thoughts - no questions :>)
Recently I bought an AC-4 power supply (serial # above 55,000) that had
parts missing. Basically, and I knew it, the $43 (included shipping) was
buying a cabinet, the three pronged power cord, the main cord with cinch
connector, the fuse holder, the L-C's for the power line, the terminal
strips and the transformer. Mike's (WB8VRG) AC4R rebuild kit was also
needed to complete the parts. I prefer to buy Mike's rebuild with the PCB
assembled. For the extra $15 I know that it was done well. So, with the
kit and postage another $86 goes into the project. In this case the cost of
a set of components for an AC4 comes to $129.00. Then you have to add TLC,
some enjoyable time at the bench and the proverbial smoke test. .
Considering all of the warnings about how a failing supply can take down a
rig, rebuilding is an insurance policy. Plus, when those caps melt down it
is a real mess to clean up!
So, when looking at Ron's (WB4HFN) price range for AC-4s from $48 to $193.50
with an average of $106, you have to assume that the above average ones are
rebuilt. If a professional adds the TLC and does the rebuild, then another
way shipping would be an additional cost for sure. Then the fair price
should be at the top.
