What is there not to understand? It has been my contention that benevolently driving a 600Ω load is not an easy thing to do independent of it being resistive or reactive. Since this is about 600Ω LCR units, Tre asked about mosfet followers. Since I hadn't tried the exact combo he asked about but have experience with a similar situation of using a buffer to drive a difficult load I offered that example. As for the grid of an A2 tube, that is also a difficult load but unlike the benign flat impedance of the 600Ω LCR, it varies substantially. The key point here is with an A2 tube, you are stuck with the load the grid provides and if you choose A2 you must find a way to deal with it. With a 600Ω LCR, within limits you have the option of changing that value to something that is easier to drive without compromise. Thats my opinion and I'm sticking to it :-)
