[Amps] Henry 2KD-4 Blower Replacement

[Bill Putney]

I'm sure this has all been covered here in the past so, if you want to, 
you can reply offline.

I have a Henry 2KD-4 amp. It's in good shape except that the blower has 
gotten so noisy people complain about it on the air.

I took the bottom cover off the desk unit and it looks like there are 
nuts that hold the blower to the bottom of the PA deck. Do I really have 
to take the PA deck apart to get to the top of those screws or are they 
studs?

Henry has always been so good about their mechanical design that I can't 
believe they'd make something like a blower replacement something you'd 
have to take the whole amp apart for.

A follow up question, what have people been using for blower 
replacements these days. I'm looking for something that will fit, put 
out >30 CFM at 0.1 "-H2O, have ball bearings, and run at relatively low 
speed (I think Henry spec'd a 1600 RPM one) so it's quiet.

I'd pay some more for a quality blower that I will never have to replace 
again in my lifetime.

Thanks, Bill - WB6FRW
