RE: Class A push-pull

The inductance remains constant and the load doubles which is not critical when the tube being loaded is a triode. If you double the load and keep inductance constant with a triode, not much bad is going to happen. The belief that if you double the load, you must double the inductance stems from the use of a pentode as the tube which has an inherently high Rp making the reflected load work against the inductance to determine LF behavior. When the tube being loaded is a triode, the rP is typically 1/3 or less that of the reflected load so it dominates the impedance the inductance must work against.

I am not saying more inductance is not a good thing. Just that how you determine the required inductance is based on tube Rp for a triode and reflected load for a pentode.
