Kenwood Basic M1D Power Amp — Recapped, Etc. - $300 (Hubbard)

I'm selling (1) Kenwood Basic M1D Power Amplifier.

Very good cosmetic condition. Works great.

I will sell this with a matching Basic C2 preamp for $500 total (I have two of those listed separately).

I am an electrical engineer and have performed the following work:

• Replaced small electrolytic capacitors with Panasonic FC or FR (105°C) or SU (85°C bipolar) or WIMA film, as appropriate. Most of this was done in 2013, but the unit has seen very little use since then. The other work was done in October 2026.
• Replaced main filter caps with Panasonic or Nichicon 85°C (due to size constraints).
• Replaced 2-way binding posts with 5-way binding posts.
• Cleaned all switches and potentiometers with appropriate DeoxIT products.
• Reset the idle current in both channels.
• Cleaned exterior.
