Hi Folks:
I'm just in the middle of my first K2 construction, having completed the =
control board and front panel boards. One possible problem: performing =
resistance checks on the control board, I find that transistors Q1 and =
Q2 do not present resistances as per the instruction manual. Assuming =
I've interpreted the diagrams correctly, the collectors of both yield =
3.83K (similar to U4 out, and not the greater than 1M specified in the =
manual)--This is the pin closest to the edge of the circuit board. For =
the record the center pin of both (B) yields 7.74K, and the remaining =
pin on both (E) yields greater than 2M. Have I made a mistake somewhere; =
I've carefully double checked everything. Any suggestions would be much =
appreciated.Tnx.
