Does anyone have a source for large, high
voltage electrolytic capacitors that could
be used for a power supply for an amplifier
of about 200 watts?

Digi-Key has pc-mount caps, but the largest
are:
	10,000 uf @ 63 V (Not bad)
	 4700  uf @ 100V TSU 
	 3300  uf @ 100V TSNH 

All 36mm X 51mm (1.4" X 2") Diameter X Height

What are peoples opinions on using a 100V
cap for a 90V DC voltage?  The next step up
in voltage is 200V.  Is it necessary
to use TSNH instead of TSU?

Large capacitors mounted to the chassis really
seem preferable. (I have never seen a high-end
amp that used PC mount caps.)
