This page contains parts and kits that I have available for the Kenwood Basic M2 audio amplifer. More detail about these items is in the catalog.
This kit adds Super DLD to a Kenwood Basic M2 power amplifier.
Item # 8001002
This module replaces the Omron G2Z-222P-US 24VDC relay used for speaker protection.
Item # 8001032
The Kenwood Basic M2 and M2A were designed using special dual output transistors with part numbers DAT1018N, DAT1018P, DAT1521n and DAT1521P. This kit replaces the output stage of Kenwood Basic M2 power amplifiers, utilizing discrete transistors to replace the special dual transistors.
Item # 8001061
This speaker terminal assembly replaces the factory twist lock speaker terminals in a Kenwood Basic M2 power amplifier.
Item # 8001041
This speaker terminal assembly replaces the factory twist lock speaker terminals in a Kenwood Basic M2 power amplifier.
Item # 8001042
If you have a Kenwood Basic M2 that has an intermittent headphone jack, this is the solution! This headphone jack assembly mounts in the original hole in the front sub-panel. Three wires connect this board to the level control pc board.
Item # 8101073
The level controls potentiometers as in the Kenwood Basic M2 are no longer available. This kit replaces the level controls with an assembly that mounts on the front sub panel and connects to the level control pc board using short wires. The original knobs fit the new control shafts without any modification required.
Item # 8001074
If you have a Kenwood Basic M2 or M2A that is being used with a Y cable, there can be issues with interaction between channels. The Kenwood Basic M2 and M2A are direct coupled, as there are not any capacitors in the signal path. The interaction between channels can cause instability resulting in catastrophic failure. This module is installed on the header connector on the level control pc board. The Connector is then plugged into the module.
Item # 8005011
This pc board assembly replaces the factory input board with a new board that features high quality gold RCA connectors. It installs with the original screws without modification to the back panel or wiring.
It includes Nichicon MUSE capacitors for DC blocking that can be bypassed using jumpers that are included.
Item # 8001101
This resistor kit contains resistors that are most commonly damaged in the driver stage and protection circuit a Basic M2 for one channel. The kit includes 1/4 watt 5% carbon film resistors.
Item # 8101001
This kit contains replacement parts for the protection circuit for one channel of Basic M2.
Item # 8101002
This kit replaces all of the small electrolytic capacitors on the main amplifier pc board of a Kenwood Basic M2 or Basic M2A with high quality Nichicon capacitors.
Item # 8104004
This kit contains replacement parts for the Pre-driver stages for one channel of Basic M2.
Item # 8101013
The first differential stage of the Kenwood Basic M2 and M2A the use the uPA68H dual J-FET transistors and pair of 2SC1845 NPN transistors. Earlier versions of the Basic M2/M2A used the uPA68H, while never versions used the improved uPA68HA. The 100 ohm single turn offset trimmer potentiometers are prone to contamination and hard to adjust. The 10 turn potentiometers allow for a more accurate offset adjustment.
Item # 8101022
This pc board assembly replaces the single turn 500 ohm open frame trimmer potentiometers with sealed 10 turn 500 ohm trimmer potentiometers. A completely assembled set of 2 are included to replace the bias adjust potentiometers in both channels.
Item # 8006002
This kit replaces all of the critical components in the Kenwood Basic M2 power meter circuit.
Item # 8101024
This kit replaces the power switch of a Kenwood Basic M2 power amplifier. The kit includes a power switch and .01uf 250 VAC ceramic disc capacitor The switch mounts in the original holes using the original screws.
Item # 8101016
This kit replaces the factory 2 prong power cord receptacle on the back panel of a Kenwood Basic M2A power amplifier. The kit includes a IEC power inlet receptacle, template and a 10 AMP IEC power cord.
Item # 8001011 - 6 ft
Item # 8001012 - 3 ft
