Marconi CR100
Hi all. I am currently working on my CR100 and having changed numerous caps including the the multi value can I have come across a problem with C88 and C87 in the manual it states they are electrolytic but there are no markings on them stating they are . I know that normally 25uf are electrolytic I just want to make sure . The markings on the caps says Dubilier type 4001 any guidance would be appreciated thanks Chris.

Re: Marconi CR100
Yes same here but some of the wiring has been replaced previously . All the metal caps have a date of 1952 as has the name plate .
