For crying out loud! Which way are the plates on all of the other plate
dissipating caps oriented? Look at those for 813's, 4-400's,
4-1000's.....they'e all with horizontal fins. I don't recall seeing any of them
with vertical plates anywheres. I'm not saying that they're really needed but
there's nothing wrong with putting them on as it will definitely help somewhat
with the cooling.
Just my 2 cents worth. Fern

To each his own. But from my point of view if there was to be anything
gained the tube manufacturer would have put fins on that part of the tube.
I would also guess that they would have had the fins in the proper
orientation to air flow with air blowing thru the fins and not across them.
I suppose pure silver power cords will be the next fad here.
