[QuadList] AVR-1 info

[Glenn Gundlach]

Hello wizards of antiques,

The last operational AVR-1 at CBS TV City failed a few weeks ago. The 24 Volt supply pass transistor (Q1 of 3) shorted and took out a few other boards. I have it mostly repaired and was finishing up transistor replacements when I found the fan needs replacement too. I have a fan but the old fan was blowing down. I have 2 more units with one blowing down and the other up. I think the air plenum above the power supply drawer sucks IN so the fan should blow up. Is this right?
