What tubes are you using;CJ Prem.5

Thanks indeed Fonsy. Mine must be in great shape. I can't believe how it walks over my newly re tubed Def.7 Mid to top end just as you describe. Sure sounds like the 500 mod is money well spent.We also agree on the sound of these two tubes. In the unmodified state the Siemens more of the top end /female vocal /piano/magic.Thanks again.

Avguygeorge: Just to let you know that I have known Fonsy66 for a couple of years now. Believe me when I tell you, this guy knows his stuff. He has had more equipment in his house than you could imagine. None of what he tells you is at all an exaggeration. I'm sure you will be pleased with these recommended modifications & find them well worth the money.

Hi Fonsy & Sager,I talked to Bill yesterday. Nice accommodating guy indeed. Gotta get some boxes;and off they will go.He will return them in some new factory boxes. We are going to do the rcas,binding posts,install iecs,the wiring and mu follower.Can't wait.Don't tell him but the price is unbelievable. And yes on the Svetlanas.Thanks for your input and help guys.What a place to belong to!!!!The funny thing is I love this amp already. I'll probably be quite hard to live with after.

Avguygeorge: Your quite welcome, but Fonsy deserves all of the thanks. Wait until you get these things back. Then you will be really thanking him. If love the CJ 5's now, I'm sure your going to be in awe when you hear it with the mods. I don't want to mis lead you. I have not heard Fonsy's amps, but I've known him for a while now & he & I have very simular sonic taste. If he says it's incredible,it is. He tells it like it is. We both feel that just because a component cost a lot, that doesn't nessasarily make it sound great. I can't wait to hear your reaction when you receive these amps back with the mods. Most of all, enjoy....sagger

I also have a set of these (on loan but I may buy them soon if the price works out ok). I retubed them with Svets - good call on those, I think they are the best. also tried some JJ/Tesla E34Ls, which were nice but the Svets were better, smoother. I also did the small signal tubes, those made a nice difference. Went with RCA Clear-top 6FQ7/6cg7s (NOS, 1960s) and for the 5751 used a 1963 NOS Raytheon. Have heard good things about the Sylvania Gold Brand 5751 but those are hard to come by.

I believe Parts Connection(?) also has an upgrade kit for these amps for about $120, (http://www.partsconnection.on.ca/public_html/tpc/pkulist.html) which replaces some components. after reading this stuff I may (if I buy these) end up sending them to Bill T. to have him do the mods mentioned above as well. (sounds like they are worth it). Would be nice to have IEC power cord capability.

thanks and let us know your results.
