[Amps] XFMR Wanted

[Dennis12Amplify at aol.com]

Arne,

 I suggest that you go to a hamfest, or your local CB shop, and purchase a 
DEAD CB amplifier made by D&A corp..

 It is my understanding that Delaney and Adams were 2 HAM operatrors out of 
Scottsbluff Nebraska who often appeared in full page adds in Popular 
Electronics, etc., promoting NRI training as examples of how successful some of their 
graduates had become.

 The transformers in the Maverick and Phantom series should work for you, but 
they may only have a 120vac primary. (So just use two of them and put the 
primaries in series across 240 VAC and parallel the secondaries, being careful to 
phase them properly)

 The Maverick had 2 of them and the Phantom had 3 of them and they were 
almost always the heavy duty Stancor 'P' series which had center tapped 12vac 
filament windings and center tapped high voltage windings that could produce 700 to 
1200 VDC (depending on the caps, the filter, and the rectifier arrangement) 
at 350ma. or better.

 The Maverick ran 8 sweep tubes and the Phantom ran 12 sweep tubes.

 The Phantom power supply, with it's three transformers, would be able to 
hold 950VDC with a 1500ma. plate current drain from a 120VAC main supply.

 Since the sweep tubes cost so much these days, it's pretty easy to find dead 
units in CB shops or at Hamfests that can be had for next to nothing, (I can 
typically purchase a complete chassis less tubes for under $10), and they are 
great for scrounging parts to fix those old tube HiFi and Guitar amps.

Regards,

Dennis O.
