[Heath] Replacing HV caps in DX 100 and DX 100B

[Glen Zook]

Considering the original tolerances of the capacitors, you can use 120 mfd or 150 mfd at 450 volts and still be well within the original tolerances with modern capacitors.  However, I like to use 220 mfd at 450 volts when replacing the 125 mfd at 450 volts capacitors in the older Heath equipment.  Have had absolutely no problems with the higher value capacitors.

I need to replace  the HV caps in a DX 100 and a DX 100B and note that the original caps are 125 mfd and are two in series to get the rated HV rating. Just curious what most greenies use to replace those HV caps?

I know of a source for 100mfd caps at 600 Wv. each  and two in series 
would give me 50 mfd at 1200 WV or could use four to end up with 100 mfd at 1200 WV. I don't think a total 100 mfd would be a good idea due to 
the surge required at turn on. What are your thoughts based upon your 
knowledge and experience gained by replacing the caps in old DX 100s and DX 100 Bs?

Thanks for your input. 73, John, K5PGW
