I would like to have one power cord with a Y connection to the KPA100 -
and have the KAT100 get it's power internally in the EC2 from the KPA/100. I
would like to be able to have all three modules (the K2, the KPA100, and

Note that the
G'day,
All I do is common the individual power leads to the K2 and external
KPA/KAT at the power supply. Seems the simplest thing to do and ensures
the correct power up sequence. No diodes required, no voltage drop on the
KPA lead passed through to K2. Things can be made too complicated,
A piece of cake! At least so far... The control board and front panel
went together very smootly, and the results of the resistence checks are
within limits. Now remains the tricky part, I guess. I haven´t counted
the number of toroids I have to wind, but it´s quite a few, hi!

Oops,
on my previous post regarding my KX1 power output, I fotgot to mention that I
was running on a 13.8 volt power supply. Should I get more than 3.5 watts?
