[Drake] R-4B C90 Needed

[W9CW@aol.com]

I need to find a suitable replacement for C90 in the R-4B - the 4 section electrolytic filter cap.  It decided to fail today taking the diode string with it!  C90's capacitance values are as follows:

100uf@200VDC
100uf@200VDC
100uf@200VDC
20uf@200VDC 

Any ideas where I may find one, or am I facing replacement with four separate individual electrolytics?  When Drake was selling out its parts stocks, I purchased new electrolytic cans for my R-4C, but unfortunately not for the R-4B.

Any suggestions would be greatly appreciated.

Tnx,
