1. [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)
2. [Amps] FL2100B Amp (score: 1): Author: gschafer@mediaone.net (Gary Schafer); Date: Sun, 03 Mar 2002 18:34:31 -0500; I just saw in the new Digi Key catalog that panasonic now has some 500 volt electrolytic caps. Don't remember if they come in 100 mf but they do have them in 220 mf. Better yet. I think they are arou; /archives//html/Amps/2002-03/msg00035.html (6,611 bytes)
3. [Amps] Glitch resistors (score: 1): Author: gschafer@mediaone.net (Gary Schafer); Date: Sun, 03 Mar 2002 21:36:08 -0500; I am working on an amp with a pair of grid driven 4-400's. What size glitch resistor would be recommended for the plate circuit ? Also what do you do about the screen ? Also what would be good for pa; /archives//html/Amps/2002-03/msg00038.html (7,360 bytes)
4. [Amps] K2AW E-Details Needed (score: 1): Author: gschafer@mediaone.net (Gary Schafer); Date: Mon, 04 Mar 2002 10:30:59 -0500; I think this is it. siliconalley@juno.com 73 Gary K4FMX; /archives//html/Amps/2002-03/msg00047.html (6,909 bytes)
5. [Amps] Glitch resistors (score: 1): Author: gschafer@mediaone.net (Gary Schafer); Date: Mon, 04 Mar 2002 10:44:02 -0500; This is a wire wound resistor ? I should have mentioned before that the amp has separate electronic regulated screen supply with a 12AX7 and a 6L6. My concern is how to protect the screen in case of; /archives//html/Amps/2002-03/msg00048.html (9,195 bytes)
6. [Amps] Blowers (score: 1): Author: gschafer@mediaone.net (Gary Schafer); Date: Tue, 05 Mar 2002 10:23:21 -0500; You asked about overload at "0 static pressure". That is where the motor is working hardest moving the most air. If you hold your hand over the outlet of the blower choking off all air flow the blowe; /archives//html/Amps/2002-03/msg00089.html (8,026 bytes)
7. [Amps] Blowers (score: 1): Author: gschafer@mediaone.net (Gary Schafer); Date: Tue, 05 Mar 2002 10:48:14 -0500; There is an excellent article titled "Forced-air cooling of tubes" by William Orr in the September 1967 issue of QST Page 20. He discusses air requirements for various tubes and blower sizes. Very wo; /archives//html/Amps/2002-03/msg00091.html (8,935 bytes)
8. [Amps] 7094 Tube (score: 1): Author: gschafer@mediaone.net (Gary Schafer); Date: Tue, 05 Mar 2002 11:04:38 -0500; They are similar in power capability to the 813. 125 watt plate dissipation. However they operate at a lower voltage than the 813. I always wanted to play with some but they are next to impossible to; /archives//html/Amps/2002-03/msg00094.html (7,096 bytes)
9. [Amps] Fans for 4cx1000/1500 question (score: 1): Author: gschafer@mediaone.net (Gary Schafer); Date: Tue, 05 Mar 2002 13:33:21 -0500; Interesting thoughts Ian. Would you think that pressurizing the output compartment on an hf amplifier with a tube like a 4CX250 or a 4CX1000 would be practical? It sure would help on the 4CX250 if so; /archives//html/Amps/2002-03/msg00098.html (11,677 bytes)
10. [Amps] Oil cooled (score: 1): Author: gschafer@mediaone.net (Gary Schafer); Date: Wed, 27 Feb 2002 14:51:36 -0500; A couple of suggestions: Rather than convert it to another cooling type you might consider removing the blower and mounting it outside or in the next room or even under the table and running an air d; /archives//html/Amps/2002-02/msg00308.html (9,295 bytes)
