Hey guys one of my vintage tanks needs caps i think.
Weak verb, not the tubes or the tank.

Thanks guys

I buy stuff from Antique Electronic Supply in Tempe, AZ.
Helpful people and quick shipping. http://www.tubesandmore.com/

I would use the Sprague Atom's.
Double check your schematic but I think you'll need:
(2) 25uF 25v
(1) 250uF 25v
(3) 40uF 500v

The replacement is pretty easy to do if you are into that sort of thing.

Good Luck!!!

Antique Electronics has 40uF/500V capacitors. It is OK to use a cap with a higher voltage rating:

http://www.tubesandmore.com/scripts/foxweb.dll/moreinfo@d:/dfs/elevclients/cemirror/ELEVATOR.FXP?item=C-SA40-500

In general, you can increase both the capacitance and voltage rating. A 47uF/500V capacitor would also work and it would not cause problems in the Fender Reverb power supply circuit:

Unfortunately, guitar players excel at hearing with their eyes and they can convince themselves that they can hear a difference. Some believe they can hear a difference between 450V and 500V electrolytics, even in a power supply that runs at only 250V!
