installing fan in used empty Mark IV headshell

[Monsta-Tone]

Both of mine have small 'L' brackets that bolt to the fan, then the brackets are screwed to the cab.


Just make sure that you put it in a place where it will not be touching anything, and where it will be a little distance from the cabinet so that it can actually move the air.

If you have a Mark IV cab already, you will see 2 or 3 holes in the cab where the fan was originally.

In the head cab that my Mark IV came in, there was just 1 aluminum angle bracket that bolted onto the V shaped hole at the front of the amp. You will have to pull the grill cloth covered piece of wood off to get to it. This is how you change tubes on a Mark IV head. It is held on by Velcro or some similar type of fastener.


Hope this helps.

I almost forgot.

Make sure that the fan is fairly quiet. Most Mesa fans are silent. I have a generic aftermarket one that makes a lot of noise.
