Hi Ed,
Been there done that. Restored a bunch of them. You can get the parts from Mouser at
800-346-6873. They are great folks to deal with. 2000 PIV diode #583-R2000F, $.35 ea.
Cap #140-XAL35V2200, $1.98. Word from the wise. Replace those HV caps and all the
resistors in the HV circuit.  The caps can be gotten from Antique Electronics. They are
Orange drops .05 mfd 1600v.  Use two in parallel to give .1 mfd. They work fine. Luck and
73's.
