Remember I have been asking for the TOKO 87BX135 autotransformer . This part was not avaiable anywhere . As a matter of fact even the TOKO suppliers had no idea . I have to tell you that I consider myself pretty stupid because instead of looking what the part was doing , I kept on chasing the part . In combination with MC 14011 CP the transformer ( 1:1 ) supplied 12 V in the symetric power supply . ( +12V 0 V -12V ) For the Sandbanks PI detector , a CoilTronic CTX50-4 will work just as good . You may also substitute all by using the Intersil HIP1011 . Now I can slam it together and see what this Sandbanks is good for . Cornelius

Re: Autotransformer
Tr4 = E113 = BF256B = N Channel FET ( field effect transistor ) Tr6 = E1761 ( E176) = replacement not known by me = P Channel FET . CorneliusComment
