It could be 1/4 or 1/2 wave depending on frequency and the tubes internal
and circuits distributed C. Most 144 and 220 amps were 1/4. On 432 they went
to 1/2 or even 3/4 depending upon the designers preference.

Ok .. lets revisit this thing again ...
with a new question ...
http://www.flickr.com/photos/kc7noa/3261632257/ this is the input and im
thinking that its a coaxial input ... and with that thought is it normally
done with 1/4Wave sections?
..IE im thinking that measuring the length will get me close to the
operating frequency of this amp ....
