The tube sheets for the 2A3 and 6B4G and 6A5G all list a load of 2.5k. I notice that many of the folks here use the James transformer with 3.5k primaries. Is this because of availability, or is there a benefit to the slightly higher impedance? You loses a bit of power, bvut I am not worried there.
I am ordering some custom wound EI output trannies, so I could spec out either 2.5k or 3.5k (or even 5k) plate loads, so I was wondering.
Thanks
