Replacement fan for a guitar amp Marshall AVT50 - I need to WAIL!!

So I get this amp off of EBAY. Got a great deal but there are a couple of issues (one I knew about one I didn't so I'm debating over a proper feedback). Anywho, there is a little cooling fan that blows over the circuits of the amp (in the head area of the amp). It is very noisy (like the bearings are going out or are gone). So I take the top off and look at it. It is probably 2 inches square (roughly) and it says "24V" on it. Looks like a PC case fan to me.

1. I can disconnect the fan from the circuit board and the sound is gone but then I risk overheating, is it smart to just disconnect it?

2. Is it smart to try and replace this myself or am I going to get zapped into kingdom com if I try to mess with it?

3. How do I know what replacement fan I need (sizewise in mm and amp-wise) the model number does not help me when I search it.

Okay. It's a 24vDC fan. For the size, you take a ruler and measure along one edge of the enclosure (if it's a square). If it's a circular enclosure, you measure the diameter.

www.mouser.com and buy a replacement of the same size and same voltage. Amperage shouldn't matter. Then just hack off the connector on the original fan and e-tape it to the leads on the new one.

If you're really stupid, just tell me the size, and I'll pull a part for you from Mouser's catalog.

:thumbsup:

I've done this on a rack amp...pretty easy
 
Hopefully the night crew is better informed and can help more than the lazy-ass day people on here....slackers 😉
 
That's a standard "box" fan. Take it to a Radio Shack and you should be able to get a replacement for about $6.

I really am stupid. By my pics tell the story...size, model, amp, ect!
 
if the amp overheats it will just turn off. i wouldn't recommend running it without a fan though. if you're impatient, put a box fan or something behind the amp until you can get it fixed.
