Hello all,

I'm building a 10 meter mono band amp for my m/m contest station here in VA.

What is the group consensus on what diameter the conductor for the plate tank circuit?  I tried looking in the archives, but it's not the best for searching (it's monthly).

I'm thinking 3/8 inch should be fine.  Half inch is starting to get 'stupid big', IMO.

Will be an 8877 @ 4kv.  Class of operation: not sure of yet.  12 volt bias is probably fine.  I ONLY run CW.

And, looking for a filament transformer for the 8877.  Anyone have one that is not in use?
