[Hallicrafters] Bucking Transformer

[James Liles]

Hi again Larry:

Forgot to mention, this is a great inrush limiter as well.  Especially if 
you have converted to solid state rectifiers.

Kindest regards Jim K9AXN

Good afternoon Larry:

If you want to try something different, and the load is fairly consistent,
insert a Polypropylene motor start/run capacitor in series with the AC.  Use
30uf to 40uf per 100 watts to bring it down to approximately 110VAC to
117VAC respectively.  I know it's different but it works just fine for
receivers.  The 450VAC caps, don't even begin to get warm.

Kindest regards Jim K9AXN

I got the diagram from Todd, KA1KAQ, for constructing a Bucking Transformer.
I am familiar enough to see the device is simple to make, but not simple
enough for my limited electrical knowledge. Radio Shack is of little help
these days so I depend on folk like all of you. Japanese swords, Spittoons,
67 Nova SS, Adobe Photoshop... I am good with, electronics = just enough to
help save the stuff.



So, I need to know where I can buy two bucking transformers, one for the two
in-service Hallicrafters (SX-16 & 28) and one for the 1929 AMRAD in the
living room. I am sure my late father has one in his basement, as I seem to
recall seeing it, but the parent's home in Grass Valley, CA is 454 miles
North and I am not headed that way for a month.



Suggestions, besides studying another topic.



Larry
