keyword=Right Arm top VDC U-plane thresholds
Cards U1 through U6 had a floating threshold, but all 6 cards were tied
together. Cards U7 through U23 had a threshold correctly tied to the
threshold power supply. I repaired the solder joint between the U6 and U7
amplifiers, so now all the U-plane amplifiers are correctly tied to the
threshold power supply. Perhaps you confused this with the top VDC
V-plane amplifier V23, which I pulled from the socket and inserted a
grounding tab. V23 is the last card on the high momentum end of the VDC.
The V23 repair is on the to-do list for Tuesdday.
