Working & Recapped Apple Macintosh Classic / Classic II Analog Board 630-0395

* Item Description

Recapped Apple Macintosh Classic analog board, complete, tested, working. 630-0395-8.

Compatible with both Classic and Classic II models. That said, make sure your machine has the Rev. A yoke connector, shown in photos. There are two types, and this board is not compatible with the Rev. B connector.

All electrolytic capacitors are replaced with properly rated equivalents. The optoisolator has also been proactively replaced, since these are observed to fail with age.

Voltages (+5v, +12v, -12v) are tested and strong, and the video circuitry displays a good, sharp image.

This is a restored, used part, with signs of age and use (scuffs, dirt, etc).

Note: The speaker surround has been torn and it buzzes slightly when playing sounds at higher volume.

There was a typical amount of corrosion, particularly underneath the power circuit. I cleaned off and neutralized the corrosion, then I tinned much of the affected copper to strengthen and protect it. I also reflowed many of the solder joints.

I am confident in the work performed and see no red flags. That said, this is restored vintage tech, I offer no warranty or guarantee, and I do not offer returns.

Note: I have fine-tuned the potentiometers, but you may need to perform some adjustments after installing the board to tune it for your specific CRT. It can be done easily, but make sure to use non-conductive tools.

Ships with UPS or Canada Post / USPS, whichever is most practical. Import charges, if any, are the buyer’s responsibility.
