Anode and grid protection

Glass coated resistor replaces L2. Also extra capacitor (3300-4700pF x 6kV) needs to be added in parallel to C25. I don't have it done yet for 2 reasons. I don't have antenna for 160m (big problem), and I can't find a suitable capacitor (smaller problem).

8x47pF are added in parallel with existing grid bypass capacitors (4 per tube).

 

In parallel with C38 and C39 2x0,01 1kV capacitors were added.
