[Heathkit] Redoing SB-610s - Missing Caps

[Carl Lowry]

I'm redoing a couple of SB-610s with new caps. Having problems locating the  3 Biggies: two  .1mfd at 1200vdc & the .15mfd at 1600vdc.
Have located the other caps including the 4 electrolytics & the various tubulars.
I've checked Antique Radio & Surplus Sales of Neb without any luck.
Any suggestions for locating them please?
Any problems in substituting the Tubular Caps for "Orange Drops" ?
Thanks Guys
