[Collins] Cap questions.

[kiyoinc at attglobal.net]

Just got the Mouser catalog and I'm putting together a wish list (also
sending this to the Collins list).

My questions.

1. Page 451 - Cornell Dublier - Snapmount High Ripple Aluminum
Electrolytics.  

What does High Ripple mean in this context?  It doesn't sound like
something I want in a cap. The prices and specs look good though.

2. If the old Power supply uses 125 ufd caps, modern 120 ufd are well
within spec due to tighter tolerances.  However, if I pay twice as much,
I get 330 ufd caps and a stiffer HV.

Will there be a problem with inrush current at power on?  I'm worried
about my old transformers.   

3. Anyone have a list of "recommend you replace these caps"?  I can pick
the electrolytics off the schematic but does someone already have a list
of the form:

  C47  - 40 ufd 150 VDCW - Electrolytic
  C190 - .1 ufd 150 VDCW - BB

I'm interested in the Heathkit SB-303 and the Collins 75S-1.  

It would save me a couple hours of work if I could just fax the list to
Mouser.  

4.  I think I've found a cap that will fit 3 in the 75S-1 electrolytic
can.  Looks like .438" diameter caps will fit.   Has anyone done this?
