I am placing an order for replacement caps and diodes for this little old Altec mixer I'm restoring. I'm kind of a dunce when it comes to selecting replacement diodes. Here's the manual, (schematic is on page 8):

1 pair is for a 340V B+, the other pair is for a 12VDC heater power (3 bottles).

Anyand all suggestions are greatly appreciated.

Thanks!

1A 1000PIV rectifiers such as 1N4007 for the high voltage, and 3A 100PIV--or better--rectifiers (e.g., 1N5402, 1N5404) for the heater supply. Regular silicon rectifiers are fine; don't worry about exotic audiophile stuff.
 
Thanks NY Dave. Got time for another dumb one? C18, the output coupling cap is a 1.0 uf 400V cap. I'm not finding such a creature at Mouser. Would a pair of 0.47 uf orang drops in parallel be OK?
