Joe,
I had no clue about adjusting the HF Auto.? I have read the manual, but I think I need to read it several times to obtain a better understanding.
Yes, I too miss the Heathkit days.? I am presently looking for a good deal on an excellent condition Heathkit 220 amplifier.? They still have an awesome reputation even after many years.? With a few mods they seem to do well.
In the 70's, I felt the Heathkit Battery Eliminator IP 2715 was one of the best power supplies around and I enjoyed assembling and using them.? Now I have the Antron -70 AP-M and it is kind of hard to beat.
Many people do not realize how easy it is to convert computer ATX power supplies into 12 volt/5 volt bench power supplies.? It only requires a tiny circuit board.? I have converted so many that I lost track of how many.? An 850 watt ATX computer power supply can give 70 amps output and I have used them to power RV's, radios, etc.? They work extremely well and their longevity even at massive amp output is amazing...
