Details of K3 amplifiers

[Phil Hystad-3]

My K3 has two power amplifiers: 10w and 100w.

Question:  does the 10w feed the 100w in that the signal is amplified prior to input into 100w PA?  Or, is the input of the 10w amp the SAME as the 100w amp such that the 10 w is Bypassed for power > 10w.

Thanks,

73, phil, K7PEH

Phil,

The 10w PA transistors are always in the circuit - their output feeds
the KPA3 input.
