Many people answered, and all of them were correct--
except for the non-available part.

CE Distribution recently started manufacturing their own
quad capacitors in their own facility in Mexico.
They come in values commonly seen in vintage tube
amps; 20-20-20-20 at 475v, 40-20-20-20 at 525v, and
now a dual 100 uF at 500v. I think the 40-20-20-20 will
be suitable for your old console, with the 200 uF 50v
section replaced with a separate axial capacitor.

They are all sold by Antique Electronic Supply www.tubesandmore.com.

(I know about these, because I fix a LOT of vintage hi-fi amps.)

...should be qualified: virtually ALL such capacitors have the
center pins POSITIVE, with all their NEGATIVE ends
connected to the can. Can-positive caps were once made, but
are rarely seen except in things like HH Scott hi-fi integrated
amps from circa 1960. They were used to filter the negative
grid-bias voltage for the power tubes. You need can-negative.

(and btw: 6137 is the date code, 37th week of 1961.
1013 is a factory code.
"FP" is the Mallory series ID. 
Mallory's FP multisection caps were once the mainstay 
of the American electronics industry. Billions made.
Now totally forgotten.)
