Don, Australia runs 230VAC 50 Hz but typically measures around 240VAC. The arrangement you described sounds like our wiring. The system we use is called MEN or Multiple Earth Neutral system in that

Digging in more on this S107. Finding more and more that have been done wrong. For some reason when it was recapped, the person used a .02 mfd electrolytic cap (C53..I think it is on the schematic)

Ron, Do Australia houses use a hot wire, + a grounded neutral, + a safety ground [three prong plugs] so will you use a three prong plug. an auto-transformer should be more efficient. How do you

Hi folks, Thanks for the good information on the current drain of the S-38B. My intention is/was to use a Triad Magnetics TR6-120 transformer that has a 230VAC or 115VAC input and an output of 120VAC

Thanks, guys, for all the replies. That is what I thought, just wanted to check to see if some one had started it back up. 73 and happy weekend!!!!! Walt Cates,

Ron, Perhaps you are wanting a 240-120 nominal step-down transformer for use in Australia? And want it to be isolating Perhaps it will be located nearby the radio in open air? Or within the radio

we had one when Duane was alive but haven't heard a specific one in years. 20 meter vintage SSB net usually met around 14.293 MHz; heathkit net generally followed it. 40 meters:

Not sure that a higher VA rating is really necessary for this small of an isolation transformer. "It is possible to estimate the output voltage at intermediateloads since load regulation varies in an

The Vintage SSB Roundtable meets every Tuesday night at 7:00 PM CA time. Early check-ins start at 6:30 PM. Frequency is 3895. It would be wonderful to hear some of you on from the Halli group! Bob

There is a vintage ssb net I ran across a few months back and it is not brand specific. Have to page back through my scratch sheets to find the info. Think they were followed by a Heath net. Someone

Walt there use to be a net but sadly i have not heard it in years. hope they just moved freq 73 Tony WA4JQS -- This email has been checked for viruses by AVG antivirus software. www.avg.com

Does a Hallicrafters HF net exist.? Walt Cates, WD0GOF https://wd0gof.com/Hallicrafters A majority of acceptance is not proof of correctness. https://wd0gof.com/bible-study/commentaries/

Ron, I just measured my s38b and it draws 208 mA with a supply voltage of 121 VAC. I think I would use a transformer with a good safety headroom. Maybe 50 VA so it doesn't get hot. 73 Don

Hi folks, I am restoring a Hallicrafters S38-B receiver and want to add an isolation transformer. So that I can select the correct transformer, I need to know the actual current the S38-B draws. I

And I have it now thanks to Pete! Really appreciate your product!

I bought an XM receiver at a hamfest a few years ago. It was "open". To use it, you tune your FM car radio to an open frequency and simply listen to it. No hardwire necessary. I assume they still work

Working to restore a S-107. This is the first version with the 6SC7 tube before they went to the 12AX7. I can only find a schematic for the MK1 & 2 which use the 12AX7. Someone has done a half hearted
