[Amps] Triode Questions

[Aleksandar Petkovic]

I'm in the throes of building a 6m amplifier using a GS35B tube. It is 
of course, indirectly heated and has one side of the heater connected to 
the cathode internally.

I have two questions, regarding various circuit techniques I have seen 
when deciding on what I'm going to use in my amp.

1. Should I use a separate cathode choke to connect the bias or should I 
just inject it at the transformer end of the heater choke, selecting the 
wire that connects to the heater/cathode junction? I have seen both 
techniques used and I'm wondering about the advantage or disadvantage of 
either method.

2. I have seen instances where there is a capacitor from the 
heater/cathode to the other side of the heater. Then, I've also seen 
instances where this capacitor is left out. Are there any reasons for or 
against using this capacitor? In my own mind, as it is indirectly 
heated, I cant see why the capacitor would be used.

I would be very interested in any facts or thoughts on those questions, 
as I finalise my design.

Thanks and 73, Alek VK6APK.
