[Elecraft] K2 Won't power on

[Don Wilhelm]

Jeremy,

Make a quick check on your voltmeter - measure a new Alkaline battery, 
you should see quite close to 1.50 volts.

Are you making the measurement by using TUNE?  If not, you should be.

Is this an older K2 with a trimpot at R60?  If so, it should be turned 
fully counterclockwise.
Check the resistors R59 through R63 to be certain they are the correct 
values.

I would be puzzled about a bias voltage higher than 0.64 volts because 
it could lead to higher current and the resulting heat dissipation in 
the PA transistors.

Thank you for adding a bit of the prior post that you are responding to 
- it helps a lot.

73,
