jeff rowland model 6 capacitors

I'm not sure exactly which main filter-caps the Model 6 uses, but I've had a set of four Nichicon LNT1K333MSE (33,000uf 80v 3" diameter) for my JRDG Model 3 mono-blocks on-order with DigiKey for almost a year now. Still waiting.

But on the other hand, DigiKey keeps the really good EPCOS 47,000uf 100v, 3" diameter, screw-top aluminum capacitor in stock and they are a great perfect-fit upgrade for the JRDG Model 5, Threshold S-500, and other large amps that take a 3" diameter main-filter cap. Unfortunately, they are just too tall for my Model 3s

These days I finding that some of those large older-style "computer-grade" electrolytic caps are getting down-right difficult to come by.

That's odd. All the EPCOS large aluminum caps that I've bought from DigiKey of this part number are tagged Country of Origin: Germany.

I wish that I could still find the larger size Cornell Dubilier or United Chemicon caps, but many of these sizes seem to be no longer offered. Sounds like you have a nice stash there, Renjy651. Better hang on to those!

Now, occasionally on eBay you'll see a few Cornell Dubilier or United Chemicon pulls from a surplussed power supply or the like which I would avoid, and sometimes you'll even see someone selling a few pieces of NOS but you really need to check the date-code before you buy.
