Try finding decent, affordable caps for a QUAD 405 sometime. Like 10,000uF and 63v in a size that fits that space should be hard to find. But they are - oh yes they are!

** Yes, I realise that such possibilities may not have occurred as any sort of sensible proposition to other countries, but that's their problem!...
Why not simply fit sufficient capacitors to achieve the desired total capacitance, if necessary by fabricating separate modules in which the capacitors would be contained?...
I don't know!!... Today's generation?... They need spoon-feeding with everything!... When I were a lad, things were different...
were oil-in-paper and nothing Jeff found would fit into the cans. He wanted (and I did too, of course) to keep the original look of the amp. He thought he'd string them underneath if he had to but kept looking for oil-in-paper caps with the same specs or close to those specs rather than using modern caps. The last time we talked he thought he'd located some...I haven't called him for a while.

of paper-in-oil caps, then you will indeed be likely to find - since these are usually the "beefy" sized options - few options that will fit a confined space...Bearing in mind the relatively low "guaranteed to spec" lifetimes of paper-inb-oil caps, I would bite the bullet and wire up a separate ganged module of modern PIO caps to achieve the required overall capacitance if I felt than the generally rather smaller film/foil caps would significantly degrade the sound characteristics I was trying to achieve...
Whichever option you choose, I wish you the best of luck in achieving your targeted delivery of sounds!...
IE a 'clone' II.This just MIGHT - IIRC - change the cap rq't OR make it worse!?

IME well worth seeking out and doing!
the 405II was a big step forward, in PRAT! Into dynamic spkrs. BA diff into 63's IMO&E. First QUAD SS amp I really LIKED into 57's!
57's and 63's just SINGGG on* most valve amps from 10 to 100wpc, BTA even a LEAK St20 - in OEM SPEC - will still KILL a pr of QUADII's into 57's. IMO&E!
*and pure CLASS-A SS up to about 50WPC. A pr of 57's and a STAX DA80, really can ROCKKKKKK.
Crowbar protection mods are a GOOD idea for amps driving ELS's. Both 405's had this ..... I THINK!
