1. [Amps] More LK500 (score: 1): Author: Jeff Strailey <liveccam@yahoo.com>; Date: Sun, 28 May 2006 23:11:48 -0700 (PDT); My problem with operating an LK500 following the change to 120 Vac operation appears to be related to a step start mod that was added at some time to the amplifier. Perhaps someone has a schematic or; /archives//html/Amps/2006-05/msg00468.html (6,813 bytes)

This means that the resistor is permanently in series with the mains... and will be having a very hard time. Don't; /archives//html/Amps/2006-05/msg00476.html (8,225 bytes)

Make sure the HV caps are discharged and the unit is unplugged. Then get out your ohmmeter and start tracing the wiring, so you can draw; /archives//html/Amps/2006-05/msg00482.html (7,690 bytes)

Basic AC mains wiring on an amplifier should be easy to follow with a little visual inspection and an ohm meter. ______________; /archives//html/Amps/2006-05/msg00484.html (6,832 bytes)

Re: [Amps] More LK500 (score: 1): Author: R L Measures <r@somis.org>; Date: Mon, 29 May 2006 13:07:32 -0700; Stepstart relays need to have a DC coil instead of an AC coil so they won't buzz the contacts when closing.

Re: [Amps] More LK500 (score: 1): Author: R L Measures <r@somis.org>; Date: Tue, 30 May 2006 04:25:53 -0700; With the circuit at: http://www.somis.org/D_a_01.jpg the 2, step-start resistors are seriesed with 240vac and paralleled with 120vac, so the need for different resistors is obviated.
