Re: [AMRadio] 100 V filament transformer primary

If a variac is used at 120 volts, you can get 140 volts out of it, guess it depends on the variac connections. So, that kinda shoots that theory down. Regards, Gary...WZ1M - Original Message - From: "John Lyles" <[EMAIL PROTECTED]> To: Sent: Tuesday, February 20, 2007 2:30 PM Subject: [AM

Re: [AMRadio] Transformers Revised

Kinda scratching my head here, if the primary voltage is passing thru a rheostat, why the need for 100 volt primary trannys? Regards, Gary...WZ1M - Original Message - From: "ARS W5OMR" <[EMAIL PROTECTED]> To: "Discussion of AM Radio in the Amateur Service" Sent: Monday, February 19, 2007

Re: [AMRadio] Insulation Resistance

I am kinda lost on this Rick. A megger measures resistance from winding to winding or winding to ground. A megger is pretty much useless for measuring winding resistance. If you do get a megger, be careful. Some are only good for 500 volts. That's not enough if your doing HV trannys and chokes. Ye

Re: [AMRadio] WTB Tubes

Not only has tubes soared in price but transformers have also gone wild in there prices. Try to buy a 100 watt mod tranny for $15.00, now days. Those BIG voltage plate trannys, wow, unreal. Regards, Gary...WZ1M - Original Message - From: <[EMAIL PROTECTED]> To: Sent: Monday, January 01, 2

Re: [AMRadio] Shorting stick

OK, just solved a myth about wet broom sticks being of high resistance. I put a highpot to a 3 foot length of a broomstick, at 2200 volts I got the alarm. I would not use a broom stick, even covered in black tape. Use a high voltage glove if you fool with high voltages, weather it be ground or not.
