I filtered the B+ with a simple CRC filter. 100uF-100R-220uF instead of the stock 220uF.
I used #2 mix (red) toroids about 1" O.D. size and #18 magnet wire for each toroid. These will easily handle 100-150 watts of RF at the relatively low impedance levels for a tuned input circuit.
Tuned Input (Q should be 5 not 2)
Anode systems should have series-resistance in the anode lead between the filter capacitors and RF choke.
