What is the minimum order to get your own name on caps from China?

Thanks for the input, Dave.

Been looking around and, they're a non-stocked item, like you said, or
they're big $$.

I have a bunch of much shorter, snap-in caps, which I've used in the past
with good success.  They're 470 MF @ 450 VDC and 105 degree rated.  Same
dia as these, but only about 40% of the height.  Already have a PC board
made up for using 10, but easy to cut the board down to 8 to make it fit
the PS case.  If I need to make a step start, I'll have plenty of room
above the new caps where I can place it. Probably an area of about 4 x 4 x
8 inches will be available.

I may just make the time and do it my self.
Having parts on-hand makes it much better than $200 on exact fit
replacements.

Availability is probably going to be the problem....
Check with Ten-Tec....if they no longer use them...ask for a
recommendation.
Check with Henry Radio....they still have screw terminal lytics.
Recently I serviced a Henry 3KD with screw terminal caps from Henry.

Hello all,

Figured it was time to re-cap the PS for my Ten-Tec since they are about
25 years old.  The amp hasn't been used in a while so you just know what
will happen if I DON'T re-cap it before I use it.

I really don't want to change (mechanically) the way the originals are
mounted in order to use a different, possibly more available, cap.

Looking for suggestions on sources other than the 'usual' (Digikey,
Mouser,
etc...)

These caps are 400 MFD x 450 VDC, 85 degree, with screw terminals on top.
Terminals appear to be #10, with a 1/2 inch spacing.  Dia is 1 3/8 inch
and
length is 5 5/8 inches, or so.

100 degree would be nice and the capacity can be +/-.

Any input would be helpful. I just don't want to pay $25 per cap if I can
find similar for $15.
