On these 3CX-6000's and also the socketless version [ YC-243],
I fool with from time to time, Eimac/ Svetlana state's the grid
diss at 225 Watts CCS. [3CX-3000A7 is also 225 w CCS grid]
Now, since the tube(s) can be operated in either GG OR grid
driven.... it occured to me that in grid driven mode... the grid
should still has a 225 w CCS rating ???
The point here is..... in GG service... you bolt this huge grid
ring to the chassis.... and in the case of the socketless
version.... an even bigger diam grid flange is bolted to the
chassis !
Now... that alone should heatsink the grid ??? Since the grid
is sitting in a vac... the only way for thermal heat to escape is
via the grid flange.
Since the below chassis compartment is pressurized... one might
think the actual grid dissipation can perhaps be increased via
this heatsink action ?? [GG mode]
Am I out to lunch here ???
