1. [Amps] amp p/s metering (score: 1): Author: "Steve Flood" <kk7uv@bresnan.net>; Date: Wed, 17 Dec 2008 17:37:35 -0700; Is it 'better' to meter the high voltage at the bottom of a bleeder string (I have 8 100k resistors in a SB-220-style power supply), or is it 'better' to build a seperate multiplier string between B+; /archives//html/Amps/2008-12/msg00246.html (7,035 bytes)

Re: [Amps] amp p/s metering (score: 1): Author: "Carl" <km1h@jeremy.mv.com>; Date: Wed, 17 Dec 2008 20:43:33 -0500; Much better as part of a bleeder string that uses resistors that are not operating way above their voltage rating as in a SB-220 trio of 4.7M 1W carbons.

Re: [Amps] amp p/s metering (score: 1): Author: Glen Zook <gzook@yahoo.com>; Date: Wed, 17 Dec 2008 18:17:02 -0800 (PST); For accuracy I definitely would use some 1% to 5% resistors in a separate multiplier string. Use considerably higher values in the multiplier string so that they don't act as bleeder resistors. Using; /archives//html/Amps/2008-12/msg00250.html (7,894 bytes)

There are several ways to accomplish the same result. I like the B+ to B- method that I have us; /archives//html/Amps/2008-12/msg00266.html (7,784 bytes)

Re: [Amps] amp p/s metering (score: 1): Author: Radio WC6W <wc6w_amps@yahoo.com>; Date: Fri, 19 Dec 2008 08:46:53 -0800 (PST); Hi Steve, Welll, if those are also the equalizing R's across the caps, as in the '220, then it is not a good idea as the leakage of the capacitors will influence the reading. Though a clever guy migh; /archives//html/Amps/2008-12/msg00268.html (8,474 bytes)

Re: [Amps] amp p/s metering (score: 1): Author: "Bob Maser" <bmaser@tampabay.rr.com>; Date: Sat, 20 Dec 2008 06:56:57 -0800; I have a couple of WD7S meter multiplier kits that look the same as the W2DTC pic. $20 plus shipping in a padded envelope. Kit includes all components and hardware. Look it up on the WD7S website. Bo; /archives//html/Amps/2008-12/msg00269.html (9,064 bytes)

Using a calibration pot and zero center meter between the strings. Initially set it to zero. Call that the "condition" meter; /archives//html/Amps/2008-12/msg00273.html (9,913 bytes)
