That is a fair comment.JMO but if you get a 6SN7 socket that gives you a lot more options. Fairly straightforward to go from 6SN7 -> 6J5 and also gives you the option of using e.g. 7N7 or 6CG7s with adapaters. Seems like if you get a 6J5 socket you are committed to the single triodes, unless you want to buy dual triodes and only use half of them.
Isn't @leftside's amp a beauty (and a beast) ?!
In my Glenn amp, I 90+% use the 6SN7 socket via an adapter for 6J5-like tubes. Another possibility in a Glenn OTL amp is to replace the C3G slots with 2x 6J5 sockets , keeping the 6SN7 socket. I am not sure which was suggested to you @Bonddam. I like the C3G sockets and have a number of adapters for those sockets.
Perhaps today, I'll pop in some metal base Sylvania 6J5GTs. I only have full the metal KenRads, and no TunSols in this family... More toobz!As nice as the coke bottle glass GEC tubes are, I find the best bang for the buck 6J5 are the early metal base tubes from KenRad, Sylvania, TungSol, etc with foil getters.
