[ForSale-Swap] Wanted: Schematic for MFJ-986 Differential tuner

[dbp at tds.net]

Hi-
 That says it all. I am in need of the schematic diagram for the MFJ Differential tuner model 986. Or any other differential tuner schematic.
 Or, if you can point me in the right direction. I have tried downloading the manual from MFJ but the diagram does not come through.

Thanks much.
