I have a sanwa transmitter, that works with six AA batteries. I see there's a plug on left to charge them keeping them inside. Which charger should I plug??

Hi,
normaly it shoud be positiv center contact, switched by TX powerswitch (when OFF). Just a wired connection to the battery tray. If you have take a meter to check polarity and then connect an intelligent charger (B6 or something). Never just connect a wall wart as there is now charger electronics behind this sockets.
If you can´t measure a voltage it´s possible that they placed a diode to prevent shorts and leave the option to use a dumb charger (current source), e.g. Graupner MC12, FM314. Then you have to short this (sometimes there is a jumper for this) to use modern chargers as they need voltage measurement for end point detection.
