This kit is intended as an easy way to mount new electrolytic capacitors when replacing approximately 29 mm diameter multi section can capacitors with 37.8 mm mounting hole spacing CTC. This design was modeled after an Astron A-25-65 can. These were often used in vintage audio and radio equipment.

Up to three different caps can be installed, and they all share a common lead located in the center. Both 5 mm and 7.5 mm lead spacing caps up to 12.5 mm in diameter are supported. The center common lead has a trace connecting it to one of the mounting holes, making it convenient to tie to chassis ground; if you don’t want the common tied to ground, you will need to either cut out a large section of the connecting trace, or use plastic stand-offs. The spacer board sits between the new caps and mounting board and adds clearance between the turrets and cans of the caps. The optional turrets provide robust terminals for wires and other components to attach to when installing.

If you use a positive-common configuration, be wary that the cans of electrolytic caps are often tied to the negative lead (cathode), but not always. Thus, voltages may exist between the cans depending on the circuit, so space them apart as needed.

Based on IPC-2221B guidelines, this board is not to be used in circuits that may see peak voltages above 450 V assuming a typical negative-common configuration.

This kit is intended as an easy way to mount new electrolytic capacitors when replacing multi section can capacitors that are around 35 – 38mm in diameter with 46mm mounting hole spacing CTC. These cans are often used in vintage audio and radio equipment, such as McIntosh, Marantz, and Dynaco. This particular version is designed for cans where the negatives of each capacitor are common (“CAN NEG”) and directly tied to chassis ground.

Includes one capacitor mounting board, one spacer board, a hardware kit, and an installation guide. Capacitors are not included.

Capacitors of 5 mm lead spacing with a diameter of 12.5 mm or less are ideal, but larger capacitors with different lead spacings can also be used. Up to 4 different capacitors can be installed. Four extra plated through-holes tied to the outer ground ring are also provided.

A spacer board is included to be inserted between the new capacitors and the mounting board, giving them a flat surface to sit on.

Based on IPC-2221B guidelines, this board is not to be used in circuits that may see peak voltages above 450 V assuming a typical negative-common configuration.

Specifications:

  • Board material: FR-4 Kingboard KB-6165F (TG150, CTI >175)
  • Board finish: HASL (Lead-free solder), matte black solder mask
  • Copper thickness: 2 oz.
  • Screw hole spacing: 45.95mm center-to-center
  • Screw hole size: 3.5mm (#6-32 machine screw fits snug)
  • Wiring/turret hole size: 2.4mm
  • Width: 55.39mm
  • Length: 37.96mm
  • Board thickness: 1.6mm
  • Height from surface of mounting board to top of a turret: 7mm
  • Spacer board diameter: 27mm
  • Spacer board thickness: 2.0mm
  • Capacitor lead spacing: 5mm
  • Max capacitor diameter: About 12.5mm
  • Capacitor lead hole size: 1.2mm
  • Diameter of turret’s hole: 1.63mm

McIntosh MC2100, MC2105, MC2300 Can Capacitor Replacement Kit

This is a replacement kit for the GE multi-section can capacitors used inside the McIntosh MC2100, MC2105, and MC2300 power amplifiers. These cans were stamped with McIntosh part number 066-095. Other models may also use this can. High quality, genuine Nichicon capacitors rated for operation up to 105°C are used to ensure a long operational lifespan, and a custom PCB with thick 2 oz. copper provides a robust and elegant mounting solution. Four wiring turrets facilitate the connections to each of the four caps. No more gutting the old cans and sticking new caps inside!

Includes four Nichicon capacitors, one cap mounting PCB, one spacer PCB, a hardware kit, and a thorough step-by-step installation guide.

Installing this kit will require soldering, drilling out the original can’s mounting rivets, and stripping/attaching wires in a tight space. If you do not have prior experience safely testing and repairing amplifiers at the component level, please have a qualified professional install this kit in your unit.

The following capacitor values are included:

  • 82uF 200V (Replaces 80uF 200V)
  • 82uF 200V (Replaces 80uF 200V)
  • 150uF 160V (Replaces 150uF 150V)
  • 56uF 160V (Replaces 50uF 150V)

Note: The capacitor symbols (square, triangle, half-circle, dash) on the cap PCB were arranged based on the orientation of the original can in the MC2300. Other models, such as the MC2100, typically had the cans oriented differently, meaning the position of the symbols on this board may not align with your original installation.
