Marc, You have provided very little information, but D10 can short if operated for a substantial period into a high SWR (its purpose is to protect the PA transistor).
If D10 is shorted, it will produce a short on the DC input voltage. You can try removing D10 (and check for a charred T4 at the same time) and see if the K1 works into a dummy load - if so, replace D10 and enjoy. If the problem is not D10, I will need more detailed information for a 2nd guess. 73, Don W3FPR Marc G0AZS wrote: > Hi All > > I bought a previously built 2 band K1 (80m and 40m) a few weeks ago. > It's been going really well and I've thoroughly enjoyed using it... > BUT This morning I wanted to have a quick listen/QSO before work and I > went to tune up my G5RV on 80m with my Z-11 autotuner. > > Unfortunately I forgot to reduce the power before tuning (I normally > tune up with 1W or less) and I hit the tune button with about 5W from > the K1.
