Re: Dead Red continued

True but the reds are running @ 30.1 khz on all of my boards, I'm not sure
where that 24khz comes from but you sure as hell wouldn't run a Red at that
frequency.
I'm with you on the drop in replacement, on the other hand if you don't have
access to an HV probe you should be messing with high voltage transformers,
the amp board does have its over voltage protection and this needs to be set
according to the manual as would be the case if a wintron were installed.
The focus is bang on and the colour B+ is running 19 volts higher than the
red. Heater voltage is a tad lower but well within a working range.
I wouldn't let one go out like this but with a small change to the anode and
b+ this will be right. The only reason I report these results is purely for
others to see the progress not to give false hope.
Thanks
Simon
