Thanks Richard. Yes I checked all the obvious stuff first...RF gain control,
persnickety "RCV/TRCV" slide switch on the side, antenna bulb fuse etc. Also removed and checked the trimmer and coils of the IFs. I'm now focused on a -0.25 VDC bias measurement on the 2 IF tubes instead of the -0.10 VDC shown on the voltage chart. Will update as progress is made. |

Ernie, I think you may get more help by joining one of the Drake mailing lists. There is one at: http://groups.yahoo.com/group/DrakeRadio/join and another at: http://mailman.zerobeat.net/mailman/listinfo/drakelist Nearly the same people on both. In particular Garrey Barrell is quite expert and may know what has happened immediately. -- Richard Knoppow Los Angeles WB6KBL |
