The size of the spilt stator capacitor that you are looking for (will)
need to
be determined by the voltage and current that you intend to run, The
ratio of I:E determines the capacitance There are charts in the handbooks
for this purpose. Be sure to
Thanks to all for the information on the capacitor.
Now I have another question. I know that the manufactured coils of ancient
times were rated as to watts. I have a few old coils that I know the
ratings of, or they are stamped on the coil.
There are some that I don't know the ratings of,
Yep, very good points Don. What I was mostly trying to say to Barrie was
that tubes should be chosen first so as to acquire a ratio of plate current
to plate voltage that will be used and then design the tank circuit around
that. 400 Watts DC input can be achieved by 8 - 6146s in push pull
Sorry if this is doubled - I think I sent it with the wrong SMTP the first
