To order a schematic, click the ADD button. When you check out, enter details of the make, model, chassis number, etc. of the equipment you need the schematic for in the "Special Instructions" box on the checkout page. We have a vast library of schematics and if we have the one you are looking for we'll send it to you. If we do not have what you need, we'll just exclude it from your order. We also have schematics for amps, tuners, preamps and receivers by Fisher, HH Scott, Bogen, Harmon, Kardon, etc.
