[R-390] R-390A intermittent loss of Diode Load voltage

[Jacques Fortin]

Hi Jordan,

If the symptoms you report are exact (No change in Carrier Level and AGC, IF
and audio deck swap making no change) it have to be in the wiring between
P112-5 and P112-3.
If a front panel Diode Load test socket was previously fitted on this set
and removed, check if any wire connected to TB-103-14 remains which can get
short to the chassis at the front panel side.
You can also try to bypass J512-5 to J-512-3 inside the IF module itself to
check if the intermittent disappears, if so, the problem is definitely
within the wiring going to the P112 pins to the TB-103 and back.

And no, this cannot came from anything in the RF or the Xtal Osc decks.
