Just to share some info- rocket build with R'sJ Edcor 245V PT
with Sovtek AR4 - 284v on plates
with Weber copper cap (soild state simulation ) GZ34 - 278v on plates
seems to work and sound fine- not too hot etc...
Anyone else use a copper cap?
the perfect bar amp with the lower voltages....they don't want things too loud nowadays..

Re: Weber copper Cap In Rocket
I didn't use the copper cap but did go with SS recto in my Twin Tube Rocket and Rockster build.
And used a 280-0-280 PT ala Mark Fowler. Both sound nice with the Rocket very jangly 60's sounding and the Rockster a real lead guitar amp. Wow...

In theory, theory is the same as practice. In practice it's different.

Re: Weber copper Cap In Rocket
I use something similar - I needed a bridge rectifier (I was converting another amp and didn't have the tube option), so I have the module that mounts to the chassis, rather than a plug-in. Seems to work fine.
Re: Weber copper Cap In Rocket
I used to use a CopperCap but changed direction. As far as I know, it is just some diodes in a unique package, right? However, one day I actually heard that it was putting some kind of weird sonic artifact into the amp. ? I know this seems impossible but I could replace it with a tube rectifier and the noise would go away, put it back in and the noise would return. So I tossed it. It was with a Silvertone amp that I used to own. Eh, maybe there was something unique about the amp but, in any case, I avoid 'odd' sounds and anything that contributes to them - so that was it for me and the Weber CC.
Currently I run high voltage/amperage diodes prior to my rectifiers, whether 5Y3, 5U4, or 5AR4. This comes from an article by David Funk called 'Bombproofing Your Rectifier Tube' or something to that effect.

Most people stall out when fixing a mistake that they've made. Why?

Re: Weber copper Cap In Rocket
Rooster, I had the same problem in my Rocket build - i opted for a SS recto plug in the beginning, but had those weird problems, so swapped in a proper tube and it went away.

Re: Weber copper Cap In Rocket
thanks so much for the replies guys- all the best to you
I did install a GE 5V4 -it's running 270V on the plates- noticeably softer sounding with the Edcor 245 PT- then again I'm playing the quiet gigs
