[Elecraft] K2/100 current consumption problem

[Fraser Robertson]

I've just noticed that our club's K2/100 (#3764) draws excessive current on 
topband.

Going through the bands my own K2/100 (#4368) draws between approx. 15-19A 
at full power setting, (circa 100W o/p).  The club rig draws between approx. 
16-20A in the same test, but on topband the current consumption is 27A !!

I did not build the clubs rig, but the ham who built it has built several 
K2's.

Both rigs have the latest mods/screening/upgrades, including the PA 
instability fix for 80m.  There does not appear to be any instability on 
topband - I've checked on a scope and spectrum analyser.

It's possible the club's PA missed out on a mod early in it's life?

Any ideas please?  Looks like it's short of some L or C somewhere.

Thanks, Fraser G4BJM
