*Per the Wurlitzer model 120 and 700 schematics, there is an inherent design issue with the bias of the 6V6 output tubes:
-The model 120 schematic shows combined cathode current to be .120A and plate dissipation as 16.67W per tube.
-The model 700 schematic shows combined cathode current to be .144A and plate dissipation as 21.75W per tube.
In both instances the plate dissipation exceeds the Maximum rated value for a 6V6. The amplifier should be re-biased to not exceed plate dissipation of 12W per tube.

The pins are slightly larger than those produced in the USA and therefore they will fit tightly in the tube sockets and use will make reverting to NOS USA tubes difficult.
