markbass problem?

[herman]

hi all,

ive got a little mark 2 head, problem is when i switch it on, it makes a slow whirring noise, sounds like the fan is
struggling to get going but after about 30-60 seconds its fine with no noise, just wondered if this is a common
problem with these heads or do i need to replace the fan?

thanks mick.

I've got a LM2 and I've never had that problem. Sounds like a service might be in order... if needed, a new fan shouldn't be too expensive, (famous last words).

Carefully whip off the top cover and with a fine paint brush and a Hoover nozzle at the ready brush out all the dust and crap that had been sucked in. Obviously unplug it first.

It never ceases to amaze me how much crud accumulates around fans in music and IT gear.
