What do the Conrad Johnson owners or tube owners buy when tube rolling?

cj indicate that for their power amps small tubes need to be replaced every 1500 hours and power tubes every 3000 hours.

My prem8a's are well and truly due to be retubed as it has been 2 years and well and truly over 3000 hours. The amps are sounding a bit thick and lacking extension compared to when with new tubes.

I really did not want to spend $1800 on power tubes alone from cj. 16 x 6550 are expensive and another $400-500 on input tubes.

I see that Svet 6550 Winged C tubes are not available and the moment due to issues at the St Peters plant.

I decided to give the Tung Sol 6550 reissue tubes bought from Jim Mcshane for $99 per quad. Bargain.
I bought two sets of input tubes. Some GE 5751's. I bought a set of EI 6FQ7 and a set of Mazda 6FQ7's from Upscale Audio.

It will be interesting how they sound compared to the stock cj tubes.
