Re: Drake service CDs no longer available from K4OAH?
No Sir, its only a matter of browser to be used. With Firefox (V111.0 64-bit) it does not work, with TOR (V11.5.8 64-bit) it is working! Best regards Karl, DK7AL

Re: 2-C Receiver
The 4 lines use the same knob setup.. except there is only one phenolic reducer.? And, it has a split in its side? so it can shrink as the screw is tightened. Maybe you do not need 2 bushings??

Re: R4C power supply question
Same here, Steve. A Stacor Variac is used along with a 4-recepticle isolation transformer. An RCA WV-120B line voltage monitor plugs into one of the receptacles to monitor line voltage while adjusting

Re: R4C power supply question
Steve, Since that variable transformer can be adjusted to output more than 125V you might consider removing the knob to prevent accidental voltage changes. *Ken* *WA2LBI* [email protected]>
