Thanks for the response Burantek. Does the power adapter use the same jack on the BEOTALK 1200 as the telephone line or is there a separate jack for the power adapter? I have not actually seen the unit. It's on ePay and I am considering making a bid on it. If the power adapter shares the jack on the BEOTALK with the telephone line I would need to

I acquired a BEOTALK 1200 answering machine without the AC power adapter. I have determined that the power requirements are 9 VDC @ 300 mA. However I need to know the polarity of the power plug - and would be most grateful if someone could tell me which pin is positive (+) or, even better, help me obtain a schematic. Thank you in advance, Michael w1rc
