S-41G or W or Echophone EC-1A good picture of dial face
Never have found a source yet for a replacement dial face for my S41G. This receiver works good and is in excellent physical condition except for the faded dial face.
I wonder if anyone has a S41"W"

Re: HT-44 Common Problem?
Hi Floyd,
Yep, my HT-44 also had a failed 22k resistor in that circuit.? It measured 568 ohms.? I replaced it and the others which weren't so far off.? At least one 1k and one 220 ohm resistor were

Yes nice work.
If you want can you send me a PDF of the circuit and I will put it on the site with credit to you.

Re: HT-44 Common Problem?
I got some 3 watt 22k resistors from Amazon.? Slightly smaller than the original carbon 2 watt.? Will use them if the problem occurs again.

I use noise-cancelling headphones much of the time on CW and a stand-alone generator could not be heard.

Re: CW Sidetone ideas
It's been a long while, but I recall a simple battery powered stand-alone side tone generator that worked quite well by simply responding to RF . No attachment at all to the transmitter or receiver.

Thank you very much for the reply. I will look at the switch. They are old. The original power supply for the HT-45 did not come with the AMP. The power supply that came with the amp has been

Re: HT-45 tuning
Hi, Brian
Does the HV power supply still use 866A or 3B28 rectifier tubes?
If a previous owner had changed to solid state rectifiers,
he would not need the heaters on, but plate voltage off
