Hello Would it be feasable to build a 4 tube amplifier using the 4cx800 russian tubes. I calculated a plate impeadance of about 490 ohms, using (2600V 3.0 amp supply) However for a Pi output I am looking at a c1 value of about 100 pf at 29MHZ and each tube has 51pf of capacitance already, if added together thats over 200pf. How is this obstacle corrected? Manny KC4MNE _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
