On HA VDC had a problem of hot wires ~ numbers 290-300 on planes 3 and 4.
This time we ( Segal, Prout and me ) made the following:
1. cleanup all connections of the amplifiers to the wires of the TOP chamber ,
2. replaced two amplifiers U5 and V5 which were hot wires,
3. fixed weak connection on the power supply and threshold lines,
4. put threshold 3.00 V on both chambers (TOP and BOT).
5. checkout on cosmic ~ 1/2 hour run #1294- looks good.
