1. [AMPS] Iron regulated screen supply? (score: 1): Author: bjk@ihug.co.nz (Barry Kirkwood); Date: Wed, 30 Jan 2002 17:36:24 -0000; Contemplating building a tetrode linear from the accumulated treasures of years. Thinking back on the 30S-1 approach, and amateur as opposed to production budgeting. Thoughts: If one is starting from; /archives//html/Amps/2002-01/msg00314.html (8,114 bytes)
2. [AMPS] Iron regulated screen supply? (score: 1): Author: 2@mail.vcnet.com (rich); Date: Wed, 30 Jan 2002 11:17:06 -0800; // An anode PS sourced shunt 400v screen regulator is cheaper, less complex, more RF immune, and more accident resistant than a 1A screen supply. Screen dissipation is not trivial. When an old timer; /archives//html/Amps/2002-01/msg00326.html (8,506 bytes)
3. [AMPS] Iron regulated screen supply? (score: 1): Author: bjk@ihug.co.nz (Barry Kirkwood); Date: Wed, 30 Jan 2002 20:32:03 -0000; Let us get the arithmetic right: Assuming we are talking, say, 3kV @ 1A peak power for the anode, then the screen load is trivial by comparison. If building from iron collected from surplus sources,; /archives//html/Amps/2002-01/msg00332.html (10,586 bytes)
4. [AMPS] Iron regulated screen supply? (score: 1): Author: jstrohm@texas.net (Jim Strohm); Date: Wed, 30 Jan 2002 14:57:38 -0600; "Barry Kirkwood" <bjk@ihug.co.nz> said -- Or how about using more than one bleeder resistor on the plate supply? Ferinstance, if you're using a capacitor bank, pick your 450V source off the next to t; /archives//html/Amps/2002-01/msg00337.html (8,301 bytes)
5. [AMPS] Iron regulated screen supply? (score: 1): Author: 2@mail.vcnet.com (rich); Date: Wed, 30 Jan 2002 13:45:58 -0800; The screen is rated at 12w max. 400v at 1A is a big deal for the 12w screen. The zeners and power resistor to make a shunt-regulated screen supply for a 4cx1000A would be c. $20. Mr. Rauch's math co; /archives//html/Amps/2002-01/msg00339.html (8,387 bytes)
