Hello. I am building K2 #5731 and I have run into two problems. The first, and most serious, is in VCO alignment. When moving L30, the voltage at the left end of R30 does not change from 8.03vdc. I have been through the entire range of L30, very carefully, with no change. I pulled out T5 and rewound it. It is as nearly perfect as I can get it. When I measure vdc on T5, I see approximately 0.01vdc on 1 and 2 and 2.65 on 3 and 4. I checked voltages on U4 and U6 and they are in the range of the table in the back of the manual. I've checked all the components installed and the soldering. This is my second K2 and I have been a lot more careful. I'm stumped. Anybody got any ideas.
The second thing is that parts of the mode indicator on the display have become intermittent. Any ideas on that? Thanks.
