45/100: 8-32uF (preamp) / 32uF / 32uF / 32uF / 32uF
JTM-100: 16-32 (preamp) / 50uF / 50uF / 50uF/ 50uF
'67: 32-64 (preamp) / 50uF / 50uF / 100uF / 100uF? (this one is definitely totally wrong - i'm just guessing from the caps i see on the board)
Would be great if somebody more knowledgeable could chime in and complete/correct the list up to a '69 spec, or share a link to such a list - couldn't find one.
preamp 16uF axial, PI 32 (axial), screens 16uF (2 series 32 axials), mains 32uF (series parallel 32 axials x4).
Late 45/100 (EL34) and Black Flags:
preamp 32/32 dual axial, PI 16 (2 series 32 axials), screens 16 (2 series 32 axials), mains 32(series parallel 32 x4).
Late 67-68:
preamp 32/32 dual axial, PI 48 (parallel 16/32 can up top), screens 16 (x2 series 32 axials), mains 50 (x2 series 100 axial cans)
Early/mid '69 only (caps up top):
preamp 40/40 rasial can, PI 40 up top radial can) screens 40 (40/40 and 40/40 series parallel cans and mains 40 (same as screens)
Late '69 onwards
preamp 50/50, PI 100 (50/50 parallel can), screens 50 (50/50 series parallel), mains 50 (same as screens)
Odd ones crop up around 1970 with 200 cans for 100 mains but not stock
