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.
