[Elecraft] K2 EXCESSIVE PREAMP NOISE?

[Pdn0528]

I've been wondering about this for awhile and would like to get some
opinions. When I switch in the K2 preamp, I get a substantial increase in
noise....not band noise...I'm talking about no antenna connected. I haven't
measured it as yet, but the noise increase is great enough to make me
suspect I have a noisy transistor. Think that's possible?  Any comments
appreciated.
