The filter caps on this thing are rated at 30uf @ 600 volts. Jeesh!
The best I can find in the Mouser catalog are 20uf @ 600 volts.
Anyone know of a better option out there?
I'll also be re-tubing this beast with 6550's since a matched pair of 7027A's are made out of unobtanium.
Thanks for any help.

Skip Mouser for specialty stuff like these caps. Try online shops that supply tube amp parts, like http://www.hoffmanamps.com or http://www.rubytubes.com (I'm not endorsing them nor have I used them, just an example).

As a general note: Electronics supply places like Mouser, Digikey, etc. are excellent for common, general parts and decent prices. They are not so good for specialty audio parts, especially when it comes to tube-based gear!

Larry,
Thanks for the reply. Both of those sites were helpful. I found this site http://www.justradios.com/shop.html
and it looks like they have exactly what I need, fingers crossed.

How about a place that specializes in parts for old Ampegs?
