it really does fold out like this, the real image is amazing. It is
truly the roll royce of radios

| The psu was the only dissapointing part of the system. It needed 24V at
a gazillion amps. The vibratory supply gave poor regulation. I should
have fed mine with 24V AC and replaced the vibrator with diodes but I didnt have a schematic and reverse engineering it was
impossible due to its ultra compact construction. Instead I
biult
my own DC regulated supply which allowed the C13 to truly shine.
My reverse engineering was accomplished by monitoring the power harness
voltages under various operational conditions and designing something
that behaved the same ! The older C42/45 used a solid state inverter. |
