1. [Amps] Clipperton L soft (score: 1): Author: Kelly Taylor <ve4xt@me.com>; Date: Thu, 20 Jul 2017 16:58:33 -0500; Hi all, Just trying to diagnose a weak Clip L. Here's what I see; On CW, the Vp meter shows 700 volts. The transformer, when isolated, reads five ohms to the low-power tap and eight ohms across the e; /archives//html/Amps/2017-07/msg00068.html (7,398 bytes)
2. Re: [Amps] Clipperton L soft (score: 1): Author: "Joe Subich, W4TV" <lists@subich.com>; Date: Thu, 20 Jul 2017 19:51:26 -0400; 700 Volts sounds awfully low. The Clipperton L used 4 x 572B tubes with a plate voltage (unloaded) of 2300-2400V in SSB and 1500-1600V in CW as was typical in the SSB/CW switching of the day. Perhap; /archives//html/Amps/2017-07/msg00069.html (8,557 bytes)
3. Re: [Amps] Clipperton L soft (score: 1): Author: Russ Williams via Amps <amps@contesting.com>; Date: Fri, 21 Jul 2017 01:51:26 +0000 (UTC); Is it possibly running on 120 volts but wired for 240? RussKW6T Just trying to diagnose a weak Clip L. Here's what I see; On CW, the Vp meter shows 700 volts. The transformer, when isolated, reads fi; /archives//html/Amps/2017-07/msg00070.html (8,557 bytes)
4. Re: [Amps] Clipperton L soft (score: 1): Author: Alek Petkovic <vk6apk@bigpond.com>; Date: Fri, 21 Jul 2017 11:28:36 +0800; It is plausible that the previous owner has changed from a doubler to full wave rectifier. From the Clipperton L manual, the anode voltages, at idle, are 2700V for the high and 1800V for the low. If; /archives//html/Amps/2017-07/msg00072.html (11,286 bytes)
5. Re: [Amps] Clipperton L soft (score: 1): Author: Alek Petkovic <vk6apk@bigpond.com>; Date: Fri, 21 Jul 2017 11:30:23 +0800; Yeah. That's probably more plausible than the rectifier rewire theory. 73, Alek. VK6APK RussKW6T Hi all, Just trying to diagnose a weak Clip L.

6. Re: [Amps] Clipperton L soft (score: 1): Author: Kelly Taylor <ve4xt@me.com>; Date: Fri, 21 Jul 2017 07:05:26 -0500; Hi all, Great responses so far, thanks. To answer some of the suggestions; the primary is wired for the correct supply voltage (120), the factory board for the rectifier/filter components appears to; /archives//html/Amps/2017-07/msg00076.html (11,412 bytes)
