[QuadList] AVR-1 Info-LEDs replace vacuum column lights

[Peter Ford]

Hi George 

Television New Zealand use to have a total of 6 AVR1s and 6 ACR25s.  All of the machines were fitted with invisible infrared leds in the Vacuum Columns.....a mod which proved to be 100% reliable.  

However I recollect a disaster one day when a photographer from a local newspaper decided to take a picture of an ACR25 while it was on air playing a commercial break.  The flash from the camera upset the servos causing instant destruction of the tapes in both transports.

Regards

Peter Ford
