Tom WC9M Molime, IL. ---------------------------------------------------------------------- My only concern with thermisters is they increase HV transformer primary winding ESR and slop the HV regulation. At 50W load for a typical R-4 the voltage drop by the thermister probably isn't much, but 400W load for the AC-4 would probably reach the maximum permissible 10% voltage drop range adding to frequency drift during key down. 100VAC is too low methinks; I experimented with one of them for feeding my AC-4/T-4XB and the panel lights dimmed enough to make me nervous with 80W PEP CW output. Hopefully Harbach will be accepting orders soon - a few of those SS-100 jobs will make my day! 73 Jason N1SU ---------------------------------------------------------------------- Submissions: drakelist@www.zerobeat.net Unsubscribe: [EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost: [EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net ----------------------------------------------------------------------
