Tubes, heat and cooling fans

[Brad737]

Hi guys,
I have a 60-watt Mk. IIC. It doesn't have a fan. I'm looking at a new combo cab for possible purchase, and it does have a cooling fan. Is there a plug or is the fan wired into the chassis somewhere? I couldn't tell from the pics.
Thanks,
Brad

For those Mark Series amps that have/ use cooling fans there's an AC plug on the underside of the chassis near the edge next to the PT.

On your 60 watt IIC chassis there's a rectangular hole where the plug would be IF your 60 watt chassis had a plug for the cooling fan. It doesn't.

When I bought my 60 watt the fan was plugged into the outlet on the back of the chassis. It was brought to my attention by a board member that 60 watt C+'s came from the factory with no fan. Someone installed a fan after the fact and plugged into the external outlet on the back of the chassis to power it, it's a standard 2 prong plug. So just plug it into the back of your chassis.

Why bother!?! If Mesa shipped 60 watt amps without a fan (or the AC plug on the underside of the chassis for one) then 60 watters don't need a cooling fan.

After 20+ years of zero problems with heat, outdoor gigs started taking their toll on my combo. Direct sun in 98F temp is going to push any amp to the breaking point. I'd put an umbrella over it, which helped, but it was the built-in fan that did the most good. M/B knew exactly what they were doing when they spec'd that fan into the design.

Spec'd that fan into what design?
Did you read the thread?
A sixty watt C+ didn't come with a fan.
In other words M/B knew exactly what they were doing when the spec'd NO fan for the 60 watt.
