[Elecraft] [K3] Shorting K3 PHONE jack outputs (WAS OT: Stereo to mono adapters)

[James Sarte (K2QI)]

I'm assuming however that a 2 circuit plug into a 3 circuit adapter should
be fine; i.e. plugging a 3.5mm mono plug into 1/4" stereo to 3.5mm stereo
adapter, which is then inserted into the 1/4" phone socket?

Tnx,
James K2QI
