Post Re: Sony KV1320MKII tube ?

Hi All

Thanks to Steve P for posting the Sony circuit of the tube base it now all makes sense the focus connections etc

With the meter now checking the resistors, three of them had gone up in value.

1 R704 100k, now it's turned into a 135K Resistor

2 R705 390k, now it's turned into a 574K Resistor

3 R708 470k, now it's turned into a 652K Resistor

Three new resistors later, the picture is now a lot better with regards to the focus but the workshop was quite cold this dinner time, and it took about 5 mins for full brightness to appear so the tube is probably worn.
The picture is fantastic compared to before the caps and resistors were replaced.

1 R704 100k, 2 R705 390k, 3 R708 470k, 4 C608 33UF 160V, 5 C522 33UF 160V, 6 C512 10UF 150V, 7 C516 10UF 160V

Thank you to ALL who helped with the little Sony CHEERS
