[Amps] AL-1200 Tuning Capacitor Range

[Kim Elmore]

I have an AL-1200 that works very well using the 3CX1200A7 tube, but at 
the bottom end of 15 m the plate tune capacitor needs to be almost 
completely unmeshed for proper tuning. The load control is not near 
either extreme. I'm not completely convinced the PA is properly tuned; I 
figure this one has just a wee bit more stray capacitance. Would moving 
the 15 m tap one turn help this? If so, which way should I go: remove a 
turn or add a turn of inductance?
