Perhaps I should have paid better attention before my previous reply.
You asked for tuned input and I responded with output.... sorry, my mistake.
From the Eimac data sheet they show the Driving Impedance as 47.5 Ohms
for 4KV Ep, 2A Ip, 6030W output; 50 Ohms at 4.8KV Ep, 1.68A Ip, 6000W
output.
Hope that helps.
