[Amps] LK550 ALO/Meter board interconnect - anyone know what the manufacturer or part/type of the two 6-pin nylon connectors that mate with J1/J2 on the ALO/Meter board?

 Thanks (Dave) for insight on the panel meters.

Arriving to the point (on LK550) that the ALO/Meter board is suspect - either was damaged or caused damage in it's prior life. Several traces handling 12V path were badly overheated, one to the point of destruction, and the board (with a couple of previously added jumpers to bypass two of the smoked traces) is still dragging the 12V DC control power supply (simple half-wave rectified off the low voltage transformer) down to near zero when amplifier is enabled (XMIT on the XMIT/STBY switch.)

Now intend to delete ALO/Meter and rewire as if it were a LK500 or other model without ALO/Meter (hence why I wanted to understand the nature of the two panel meters.)

Next step is to find pair of nylon 6-pin connectors (equal to what are currently on the ALO/Meter board); they are physically polarized and a search through digikey hasn't found anything equivalent so far. Although could remove the connectors from the (suspect) ALO/Meter board, would rather set it aside as-is for now and source replacement connectors (on the PCB, the two connector housing are female, and the (6) pins are male.) My supply of pins doesn't include any that are the same dimension as the one used on the PCB (else I'd just stuff equivalent pins into the needed positions on the end-of-wire connectors and call it a day.)

Thanks again for the hand-holding through this saga!

Dave
