When you guys speak of the power supply being bad are you talking the main power supply that feeds 38vdc to the KSU1 board. I checked it and it was good. I know there is a power supply circuit on the KSU1 board, but without a schematic it would be alot of probing. The 10vdc Electrolytic capacitors on the board were not in good shape. The tops were buldged out and two out of three were leaking. The voltage regulators checked good as did the zener diodes. Getting alot of chatter on the relays on the right side of the board. I found a KSU1 board and hopefully will get it tomorrow. It is the same software version as the KSU1 board I have. Let me ask this. Should my voicemail card and all other cards plug up with no problem. I'm a little concerned about the voicemail card because they seem to be finicky at times.
