Up for sale here is this recap kit for the Bose 901 Series II (or series 1) equalizer.  Please understand that this listing is just for the recap kit, not the actual equalizer.

At this point the equalizer is probably 40+ years old, and the old capacitors are weak and failing. We will make them new again!

This kit includes replacement electrolytic capacitors to replace all of the old electrolytic capacitors. It also includes instructions to explain how to install everything. This does not include any transistors or other capacitors or resistors. New caps are Supertech axial electrolytic capacitors--you will get the exact parts shown in the picture. These are all high-quality brand new genuine parts, the same parts I use when I work on vintage gear.

The old 500 uf 25v caps are replaced with new 500 uf 50v caps, the old 100 uf 25v and 100 uf 12v caps are replaced with new 100 uf 50v caps, and the old 5 uf 25v caps are replaced with new 5 uf 50v caps. This is a fairly easy rebuild--just desolder and remove the old caps and install and solder in the new ones.

I will include surprisingly well-written instructions, but this is at least mildly complicated, and you should know what you're doing and have a decent soldering iron. This kit will not fix everything that could be wrong with your equipment, but it will certainly help. Please see my pictures for details.
