Does anybody have any odeas or experiences for CJ PV-10 mod? Would replacing the caps with Hovland Musicap makes any difference?

Thanks

yes, Mr. Barki.....the Hovland caps would help the reproduction of high freqs better

since you have heard my pv-10 w/ Hovland caps, what do you think ?
hehe....

ps : PV-10 si tungke masih mulus abis ya kayanya ?

Keeping the old ones to reinstall if you ever think of selling it, is no big deal IMHO. I would recommend Mundorf Silver Oil Supremes.

oops...too late...
i think i lost them two or three years ago...

the original caps were SRC by Solen, I think. If I'm not mistaken, the signal/audiol caps were the 4uFs.

SCR is the French factory that stamps out the Solen brand for Canada. SCR and Solen are identical. They also sound basic and flat gray but they are good value. No doubt a first class cap will reign over the stock ones big time. It does not take to be 4uF (very expensive per uF when talking boutique caps), 0.68uF will be super for say 100k and over power amp input impedance. And will sound better than a bigger one too.

salas,

thx for your explanation.

what else did you upgrade on your PV-10 ? is yours PV-10AL or PV-10, mine is PV-10AL (line stage only).

Salas · 23rd July 2007, 03:33 AM

I replaced once the output caps of a guy's PV-10AL as an upgrade service. Nice sound, pro human sonic traits, colored somehow, not especially neutral or powerful. I had an Ecc82 (12AU7) cascade pre of my own design too. Same circuit principals but mine used tube rectification and a battery of chokes for PSU. Was way better. I suggest you may use CV4003 for tubes also. Now I am using this , at the bottom. Its in another class entirely.
