Polo/2 28" B+

Post by PappaLazarou »

Anyone know what correct B+ for Polo/2 should be? Schematic shows a 130V rail but I some forums say 138V or 105V! I've just recapped the chassis and I'm measuring 140V.
Cheers, Mike.

Hi Grant, I believe it's fixed 15kHz. Rating label says Polo/2 28.
Theres no VGA connector or 25kHz option fitted etc.

Some time ago I missed the chance to bid on a Polo/2 (15KHz) manual with a separate sheet listing b+ voltages and heater resistor values depending on the CRT type used. I have a picture of it and it's mostly readable (probable reason why I didn't bid :D ):

Awesome Thankyou. I've got the videocolor tube so I'm spot on :-)
