Many thanks again - I checked inside the L4 cabinet and also have checked through the power supply cabinet and do not find any other problems (no burned components, etc.) so it appears I got off lucky by this single resistor being the only thing needing replacement. I did notice that it appears this resistor has been replaced once before by the apperance of the other wires soldered to the lug strip terminals. No telling how long it had been since it had been replaced though. I am going to take a trip to the local electronics store in a few days (wx supposed to be bad up here in Beantown tomorrow) and look for a replacement. I think i'll buy a few extras and tape them to the inside of the cover plate! Will keep you updated after I replace the part. vy 73 Jason N1SU ---------------------------------------------------------------------- On Behalf of [EMAIL PROTECTED] Submissions: [EMAIL PROTECTED] Unsubscribe: [EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost: [EMAIL PROTECTED] - help in body of message Zerobeat Web Page: http://www.zerobeat.net Brought to you courtesy of TLCHost.net http://www.tlchost.net/ ----------------------------------------------------------------------
