Right now I plan to exchange the electrolytic caps in or C3 ?s preamp due to
a crackling noise the is not caused by the tubes. Do you know if the
original types are still available?
Hi Peter,
There is a Mexican company which still makes multipart capacitors
(the company name is "Aero-M" or something like that), BUT their
product is reported to be of very low quality, and is not recommended.
NOS (new old stock) caps are obviously not a smart option, since
they, like the caps in your organ, are way past they're pull date.
So you're best off replacing multi-section caps with axial electrolytics.
Leave the old multi-section caps (disconnected, but) in place, and install
the axial caps inside the chassis. More details at:
If you really want to retain the original look:
I've heard rumors of a fellow who will take your old multisection
capacitors, remove all they're guts, put new, modern electrolytics
inside, and seal them back up. (My guess is that this is more of
interest to antique radio restorers than to Hammond restorers.)
