I would like to find an original transformer. 2) Somehow I think the Octal Socket for AC input on the front panel is not original, I would like to put an original male-pinned connector in its place so I'm looking for one of those as well. 3) I'd like to find a pdf or dejavu version of the complete manual, if one is available. I've already snagged the schematic from Mike Hanz's site, and that is quite helpful, but I'd like to verify performance according to the manual. 4) I have an incomplete APR-1 manual from "armyradiosales" but I'm interested in a complete manual at some point, as well. 5) Junker/Parts only receivers and plug-in's parts and/or experimentation warily checking my stock of bypass caps, Tom --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From bcarling at cfl.rr.com Mon Sep 14 08:44:58 2015 From: bcarling at cfl.rr.com (Bry Carling AF4K) Date: Mon, 14 Sep 2015 08:44:58 -0400 Subject: [DCboatanchors] FS: Antique Ham Radio HF and VHF gear Message-ID: <55F6C14A.4463.483204E9@bcarling.cfl.rr.com> REDUCE price: RARE RME-45 shortwave receiver.
