The 1650r is a killer transformer and they dont cost that much being as large and well made as they are..However its impeadance is as such that its made for 6550/kt88 so you want to make the circuit to run kt88s and then you can run el34s at times if you wish or 6L6 type tubes.
I would use the vacuum tube audio circuit that is used in the VTA 70..You can get them as the mk3 boards or the st70 or you can just build it from the schematic..I have that.The reason recommend it is,you can run 12at7s or 12bh7s or a combo of both and you have enough drive in that circuit to drive 3 pairs of outputs per channel.
