Seems the latest miniman issue relates to my posting of 01-29-11, 02:44 PM. Since RCA connected the 6.3vac heater ground to the 6CB5 HOT cathode ground they obviously didn’t want Service to measure HOT cathode current. Sams detailed service procedures made no mention of measuring HOT current so I have always measured FBX system current at the HV fuse. assuming this was a good approximation of HOT cathode current. The 128ma Hot cathode reported in the post was made on a DMM which was obviously wrong.

When miniman delicately suggested this reading was suspect, I remeasured with an analog VOM and surprise! I got the exact same current at the HOT cathode as I got at the HV fuse, both were 170ma, quite modest for well over 27kv ultor, right? I immediately edited my original post and gave the edit reason “Corrected some measurements”. There never was an attempt to fool myself or irresponsibly mislead the rest of you members as was stated by miniman.
