Hi to the group,
I have been offered a pair of new old stock 8874 tubes. These would be very
nice to have for a rebuild project, BUT with date codes in the 1980's, what
would be the normal practice to get them back to normal expected output (I ask
in the hope that this would be possible)
Should I run them up just on heaters & blower a few days, then try HV on them.
Or slowly bring HV on over a period of time??
What's would be my best options??
Any advice would be much appreciated.
Thanks,
73
