Geoff, I seem to be getting very good carrier null but then the sidebands are not correctly spaced in frq. When in AM DSB mode the modulation is not symetrical and has af response issues. Everything aligns good up to the RF phase ballance adjustments where the variable C phase trimmer works but the Variable L trimmer has no effect. Looking at the related 12AT7s with socket extenders shows no change in the L side tube no matter how the trimmer is adjusted. I may not have these trimmers at the proper range but it's difficult to tell just what that is from the manual.
It's near impossible right now for me to remove the box again and do component testing with major Rheumatoid Arthritus issues. Thanks, Bill, KB3DKS/1 ______________________________________________________________ Our Main Website: http://www.amfone.net AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
