Includes two capacitor mounting PCB kits that fit the McIntosh C26. Capacitors are not included because this model used several different values depending on serial number.
Each kit includes one capacitor mounting board, one spacer board, two #6-32 3/8" pan head phillips screws, two #6 internal tooth lock washers, two #6-32 hex nuts with tooth lock washers, one #6 solder lug, four wiring turrets, and an installation guide.
This kit is intended as an easy way to mount new radial electrolytic capacitors when replacing old multi section can capacitors around 1-3/8" diameter with 46 mm CTC mounting hole spacing. Such cans were used in the McIntosh C26, as well as many other models. These boards are a great alternative to stuffing the old cans or buying expensive reproductions.
One lead of each capacitor (in this case, the negative leads) ties to an outer copper ring which connects to two plated mounting holes. This connects them directly to chassis ground which is how these cans were typically installed. If you need to float this board, I also offer an insulator kit separately.
Capacitors with 5 mm lead spacing are ideal, but 7.5 mm can also work.
