Zenith 25MC33 Set

[bhegges]

Quick update: I purchased a replacement 6JS6C horizontal output tube from eBay and was surprised that a different tube brought the current down 20ma. The tube was listed as tested good and I lucked out, NOS tubes are priced crazy no thanks to transmitters like the Yaesu FT-101 transmitter

On my B&K 747 the tube I was using measures 111 from a scale of 0 - 120 with good starting at 65, I thought was actually very good. The new tube measures above the meter range (120+) so maybe it was NOS. I have a bucking transformer I plan to use which drops the line voltage down to 106vac and has the horizontal output current running about at 190-195ma. I would suspect as the horizontal tube ages the current will rise.

Next is to run through a full setup and put this set into use.
