Hey guys -
I'm putting together a parts list for a full recap on an early model McIntosh 4100.
I've been working on the preamp board and came across some interesting caps that look like regular electrolytics, yet do not have a negative marking on the outer case. See the attached picture. Are these actually NPs? The ones circled in the picture are C707/C708 from the McIntosh service manual.
My plan is to use Nichicon Muse ES for all NPs and then a mix of Nichicon UPW (where regular blue caps are currently installed) and UKL (to replace the low leakage orange caps) for most other positions.
I may also use some Elna Silmic II or Nichicon FG in signal path locations, or possibly even Muse ES - I think I read something here where Muse ES can be used and is recommended for all signal path locations less than 10uF even if an NP is not specifically called for.
Does this sound reasonable?
Thanks!
