[Elecraft] K3/0 power

[iain macdonnell - N6ML]

The K3/0 uses, for 12V input, the RCA jack that's normally the 12V
accessory output on a K3. This is not ideal, in that it leaves the
"hot" 12V line exposed on the pin of he male RCA plug when it's not
connected, but I suppose the intent was to use the existing K3
metalwork.

So can anyone confirm whether or not the K3/0 has an internal voltage regulator?

73,
