i have build it and its a easy project, no bias my this ...whaz up next. straight forward.
:twisted:
That Cn marked just left of the tubes? thats the neutralizing cap, made of 2 by 30mm flatwashers, the cap is connected to grid and u adjust it for the tubes to work :twisted: together,i will search for the circuit..
the neutralizing can also be done with a single aluminium plate isolated from earth and mounted between the 2 tubes right side.
U ajust it , and there by neutralize the amp, normally none is needed with 811a tubes, but Murphy u know :geek:

The amplifier is like in the sketch in the previous post.

Hi Guys,

Hmm I just rememberd... I somewhere have an 811A still in my garage.

Werner, we could use this one for the clubstation.... 500W is more then a overkill for the clubantenna :mrgreen:
