Does anyone have or know where to obtain the circuit schematic for an Elenco GF8046 Frequency Generator? Any help would be much appreciated. I have searched high and low but alas, no prospects. I was able to obtain a copy of an Elenco FG8056 but it is only a user manual and doesn't include the circuit schematic. Surely it must have existed sometime back (not even certain when this was manufactured) Thanks in advance for any help! Bill
