This board is designed to replace the two multi-section capacitors found within the audio chassis of AMPEX 440C tape recorders.
Description
This board is designed to replace the two multi-section capacitors found within the audio chassis of AMPEX 440C tape recorders.
These will not work for the 440A or B! We offer another board specifically for the A & B versions.
Installation of the board is straight forward and none of the original resistors or diodes need to be reused. The board incorporates both the capacitors and these other passive components, keeping everything neat and tidy.
To install:
- Cut the wires to the caps.
- Remove the multi-section caps.
- Some units use a transistor instead of resistor 8R1 to discharge 8C1-C, remove the transistor and terminal strip. Pads are provided for a new transistor on the board.
- Strip and tin the wires.
- Populate the board.
- Install the populated board using standoffs and the existing mounting holes in the chassis. We recommend using lock washers to ensure good connection from the board ground to the chassis.
- Attach and solder the wires. The board has the wire colours silkscreened near each solder pad.
