6883 tubes??

[George T. Baker]

Might be careful when it comes to neutralizing the finals. Although they
test about the same as 6146's, they may have different interelectrode
capacitances which will affect neutralization. I am not that familiar
with those specific tubes, but inter-caps are always a consideration when
it comes to substituting tubes in r-f circuits.
