My earlier comment about a choke with shorted turns was assuming that the supply was under load at the time of the voltage measurement. K5GW makes a very relevant comment in that regardless of shorte

The 22 uH and 1000 pF in the grid peaks at 1 MHz and rolls off at 12 dB per octave after that. Can anyone tell me why they put a 12K resistor from screen to ground? Its on the load side of the screen
