Didn't you first become aware of MF "problems" when you got everything else working better via the PP2000, and the MF wound up dropping back to weak sister status with respect to system-wide PP2000 benefits?

The PP2000 reduced the perceived amount of HF and I was forced to add SOME dBs by driving the tube at higher current. I have extra plate dissipation to drive the tube hotter but I have no gap in MF DSET transformer as it is 40mA. Here is where the problem came from.

With luck, you will soon have again a midrange that is at least the equal of the rest of your system, and you can use most of the 6E6Ps instead of having to cull 1 of 50.

Yes, in 2-stage operation the 6E6P will be using just 20mA and I will be able to use any tube. The most important is that with 2-stages I will have extra gain to burn to experiment with loading.
