I just replaced the PA's on my K2. I replaced Q7, Q8, Q11, Q13 with parts from the Elecraft PA Replacement Kit. I have done this in the past with no problems. Power is supplied from a switching power supply that supplies power to a power distribution box that has a fuse for each output. This distribution box supplies power to a small 2 meter 70cm mobile/base radio and a LED light strip. This setup has been working with no trouble for a while. Now as soon as I plug in the power cord to the K2 all of the power coming from the distribution box shuts off. I used the same power cord on two other radios and it worked just fine. So the problem lies in the K2. While working on the K2 I messed with replacing only the parts mentioned above. I went over the PA's with a magnifying glass looking for solder bridges and other faults and could not find any. This problem did not exist before I changed the PA's. I would appreciate any ideas as to what may be the problem.
