1. [Amps] Equalizing Restistors (score: 1): Author: willy@global2000.net (Bill Russell); Date: Sat, 02 Mar 2002 11:10:43 -0500; Thanks for the replies folks. I should have figured the power rating of the resistors myself......i use ohms law, must have been a "senior moment"!!! As for the swinging choke input filter, Im stuck; /archives//html/Amps/2002-03/msg00014.html (7,367 bytes)
2. [Amps] Equalizing Restistors (score: 1): Author: 2@mail.vcnet.com (Richard); Date: Sat, 2 Mar 2002 09:07:27 -0800; ? Switching to C-input and removing the swinging-choke should raise the anode-V to about 3kVDC, which is c. the same as a SB-220 and TL-922. My guess is that the extant tank components will withstan; /archives//html/Amps/2002-03/msg00017.html (8,307 bytes)
3. [Amps] Equalizing Restistors (score: 1): Author: willy@global2000.net (Bill Russell); Date: Sat, 02 Mar 2002 18:59:58 -0500; Richard, If I understand you, I can remove the swinging choke leaving just the 25mfd cap as the hv filter. If the high voltage then rises to about 3kv instead of the normal 2.2 kv, I would have to ch; /archives//html/Amps/2002-03/msg00022.html (9,139 bytes)
4. [Amps] Equalizing Restistors (score: 1): Author: gschafer@mediaone.net (Gary Schafer); Date: Sat, 02 Mar 2002 21:35:32 -0500; Bill, It may raise the voltage higher than that. With a choke input filter the DC output voltage will be .9 times the rms voltage of the transformer. That is assuming that the supply is loaded enough; /archives//html/Amps/2002-03/msg00024.html (11,189 bytes)
5. [Amps] Equalizing Restistors (score: 1): Author: 2@mail.vcnet.com (Richard); Date: Sat, 2 Mar 2002 20:55:36 -0800; Yes. Sort of. The proper screen potential is c.800v for AB1. Grid bias should be adjusted for c.75mA of ZSAC. This will be c. 120vdc. Screen V is can be obtained from a zener-string. Since the; /archives//html/Amps/2002-03/msg00025.html (10,461 bytes)
6. [Amps] Equalizing Restistors (score: 1): Author: willy@global2000.net (Bill Russell); Date: Sun, 03 Mar 2002 12:10:05 -0500; Just a note about the HV power transformer in the thunderbolt. It is 4800V center tapped at about 500 mills. I have the solid state replacement for the HV rectifiers. Bill KC2IFR Bill Russell; /archives//html/Amps/2002-03/msg00026.html (13,508 bytes)
7. [Amps] Equalizing Restistors (score: 1): Author: 2@mail.vcnet.com (Richard); Date: Sun, 3 Mar 2002 12:41:38 -0800; ? Sounds good. The CT is an ideal, half-V (c. 1700v)source of current for the zener string, 800v shunt screen regulator. A 25k-?, 40w R should drop the needed V. from instead the My a - R. L.
