  • McIntosh C26 can capacitor replacement

This kit is designed to replace both multi-section can capacitors used in the power supply section of the McIntosh C26 preamplifier. Two custom capacitor mounting boards and four 220uF/200V Nichicon electrolytic capacitors are included. These provide a slight improvement in supply filtration compared to the original parts which, depending on serial number, typically included one 160uF/200V and one 200uF/150V capacitor per can. If you need different capacitor values, feel free to send us a message and we can order them for you.

Parts Included

  • Two 4-in-1 capacitor mounting boards
  • Four Nichicon 220uF/200V 105°C aluminum electrolytic capacitors
  • Mounting hardware
  • Installation guide

4-in-1 Capacitor Insulator Kit

Insulator board and hardware for floating 4-in-1 capacitor boards

This kit can be used to isolate our 4-in-1 can capacitor replacement PCBs from chassis ground. This is useful in cases where the original installation used an insulated can floating from chassis.

Includes one insulator PCB for 1-3/8 inch diameter cans with 46 mm CTC mounting holes, two nylon #6-32 screws, and two nylon #6-32 hex nuts.

4-in-1 Can Capacitor Kit (Wide)

Replaces multi-section cans with 46 mm CTC mounting holes. Fits four 7.5 mm lead spacing, 16 mm diameter capacitors

  • Multi section can capacitor replacement

This kit is intended as an easy way to replace old multi-section can capacitors around 1-3/8″ diameter (approx. 35 mm) with 46 mm CTC mounting hole spacing. These cans were often used in vintage audio and radio equipment, such as McIntosh, Marantz, Heathkit, and Dynaco.

The capacitor board fits up to four 7.5 mm lead spacing16 mm diameter radial capacitors. Smaller 5 mm lead spacing capacitors will also fit. An alternate version of this kit designed specifically for 5 mm lead spacing, 12.5 mm diameter capacitors is also available.

The negative leads of all capacitors are connected to a thick outer copper ring and two plated mounting holes. This means the negatives will be tied to chassis ground by default. If you need to isolate this board from chassis, take a look at our isolation kit.

Includes one capacitor mounting board, one spacer board, 5 wiring turrets (one extra), a mounting hardware kit, and a link to installation instructions. Capacitors are not included. In order to save on paper and toner, we are now including a link to a PDF copy of the installation guide. If you would prefer a hard copy, please let us know and we’d be happy to accommodate.

Based on the IPC-2221B standard, this kit is not to be installed in circuits that will see peak voltages greater than 600 V.
