Team Associated TR203A Receiver, 27MHz, 2 channel info needed

[Lockheed-21]

Hello,

I own Team Associated TR203A Receiver, 27MHz AM, 2 channel.

I have a question about battery (power) connector, 1st (upper) three pin slot.

There are three pins in slot, so which one is positive (+) and which one
is negative (-) polarity pin of those three pins in upper slot?

I am not using original three pin female power connector but two pin
female power connector, that's why I ask, to avoid polarity mistake.

I know another two slots are for channels CH1 and CH2, no problems there.


Many thanks for help.

Center pin positive, pin towards outside is negative.

I always remember "Center pin positive, signal towards the safety tab," which only allows the ground to be on the far right pin in your picture.

I think that, pretty much without exception, the negative pin is closest to the side of the case.
