jeff rowland model 6 capacitors

Can you tell me the values of those?
I've seen 100,150kuf on digikey...
go to digikey.com --> select product index --> select capacitors --> aluminium capacitors --> filter values you're searching for.

yeah, some of the big caps can be expensive. And for mono's you'll be looking at several hundred dollars. I'd look at the specs for the current cap and find a comparable power supply cap.

You could also ask Jeff Rowland about what he would recommend aftermarket. He usually responds in a few days.

I'd recommend Nichicon. The big ones usually made in Japan and very good. Parameters are more important than type.

One point I forgot to mention that these filter caps in Jeff Rowland amps have been designed to have lots of extra headroom that actually not being used. Unless they show visual wear(around electrodes or shape) I would not recommend to replace them.

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.
