Gold Replacement End Caps

_________________________________________

NOTICE !

We are no longer making our line

of replacement end caps.

Our replacement end caps have always been made just like the

original McIntosh end caps - with a hard-anodized aluminum finish.

The nice glossy finish is produced by using Hexavalent Chromium (CR⁶)

as part of the hard-anodizing process.

Hexavalent Chromium is a toxic carcinogen and in 2017 was

banned worldwide as part of the RoHS directive.

It is now used only in some specialized aerospace applications.

For the past year we have worked with a variety of machine shops

and platers on this problem. We have tried anodizing the aluminum

with the acceptable Trivalent Chromium, but the finish is dull.

We have tried plating the aluminum with Nickel Chromium and

while the finish is glossy, it is the wrong color and the plating is

not smooth enough.

All of our tests and trials of materials and plating have produced

less-than-satisfactory results. We have exhausted all avenues

and have concluded that it is no longer possible to replicate

the finish of the original end caps.

Our current stock of end caps is depleted,

and they will no longer be available from us.

The listing or order form shows "N.L.A."

[No Longer Available], and that is it!

We don't have any more squirreled away in a corner.

Now the good news is that Audio Classics in Vestal NY is

producing these as of January 2026!

They have gone a different route and are making

these from aluminum bronze. The finished product

is a nice match for the originals. Contact them for information

and pricing.

These end caps were produced from 1960 to 1963. They are removable (to access side controls) and they are reversible (can be used on either side) and attach with a press-fit on two pins protruding from the faceplate.

They were used on the following equipment:

Note: These end caps have a 4-3/4" pin spacing. McIntosh made an undocumented change in the front panels and end caps during production. Some early units had a 4-1/2" pin spacing - most had the 4-3/4" spacing. The McIntosh part number was the same for both versions! Check your equipment before ordering!
