[Drakelist] Using Heath HP-23 with TR-3 or Looking for an AC-3
Greetings from Chris, AJ1G in Stonington, CT. This is my first post to the group. I picked up a TR-3 at Near-Fest Deerfield last fall. Has been sitting while I come up with a power supply for it. I picked up a Heath HP-23.as a potential supply for it this spring. From what I have read the HP-23 might be marginal with the Drakes due to the higher current draw of the Drake sweep tubes vs 6146s? I would prefer using an original or updated AC-3 if anyone has one available for sale. I would also be interested in a supply for mobile use, again would like to hear comments on use of the lete model Heath DC solid state mobile supply for the HW/SB transceivers with the TR-3. Also looking for info on using the TR-3 on AM' 73, Chris, AJ1G ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Chris - The high voltage from the HP-23 is a little high in voltage and a quite low in current capability. That said, it would probably 'work' for low duty cycle use. CW, SSB with 'typical' transmission duration, (no AM style 'old buzzard',) and no AM. HP-23 - 700 VDC @ 250 mA TR-3 - 650 VDC @ 300 mA, 500 mA peak. So the '23 won't blow up, but it probably gets pretty warm. A fan on it would help a little. Much easier is an AC-3, -OR- and AC-4. Either will work just fine. The AC-4R is a good idea with either. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-B, C-Line TR-4/C Service Supplement CDs www.k4oah.com Christopher Bowne wrote: Greetings from Chris, AJ1G in Stonington, CT.

gang with the higher ac main voltages running now, the output of the hp23 will run close to 900+ volts.. I'd never use one for the drake rigs mike bryce proso...@sssnet.com On Oct 2, 2010, at 11:20 AM, Garey Barrell wrote: Chris - The high voltage from the HP-23 is a little high in voltage and a quite low in current capability.
