[Elecraft] Using basic K2 with Tokyo Hy-Power HL-50B amp

[Jason Marten]

I'd like to use my basic K2 with this amp (5W in, 50W out) in CW.

It has an RF keying circuit, so that means all I have to do is hook up the 
K2 antenna out to the amp, and the amp to the antenna, right?  Can I ignore 
the ALC socket and other connections?

Also, as to QSK on the K2, should I slow this down to semi-QSK via 8R hold 
(I don't have K60XV) or is there something else I need to do?  The amp is 
not QSK.

Thanks.
