Doug, Nice to know! Wondering if you have a diagram for RF input circuit, where the RF signal amplitude (strength) is calculated and displayed. I'd like to pick that off and get a better reading/display if signal strength. Wondering also where the X10 attenuator is switched in too. Any information would be great!

A datasheet can be found here: http://www.alldatasheet.co.kr/datasheet-pdf/view/TOSHIBA/TA31136.html Hope this helps. If not, I have a service manual and can look up the information you need. - Doug --- In [email protected], "Bob Warriner" <Bob@W...> wrote: > Hi Group, although I have been a member for quite a while, this is my > first post. > Has anyone got a circuit diagram of the VR500?
