Running a 220 VAC fans at 120VAC (just plug them in to
the wall outlet) accomplishes the same thing. Quietly
moving air out of the cabinet. I use one on my T4XB all the
time.
220V fans are usually available cheap at ham fests because
no one want them.

Brilliant, Jim. Looks like I've got to add that to my Lowe's list :)

Great point! I have two large fans on my L-7PS, 12 volt fans connected in
series on a 12 volt power supply. They are barely audible if I really listen
for them with no other noise in the room. The IBM ethernet switch on the shelf
behind me easily drowns them out. And they do still move a good volum
You can get the same airflow by running a larger fan at a lower speed with
the benefit being lower audible noise. I have some surplus 4" fans that
have rubber feet attached and just sit over the hot portion of the
cabinet. I run them at a DC value below their ratings. They don't walk,
aren't hea

Hi, Paul:
I purchased a T4-XC with MS-4 speaker and AC-4 on the cheap. The rig, etc., are
in really nice shape and the cabinets of the T4-XC and MS-4 had been repainted
beautifully.
The T4-XC had an 80-mm square dc fan on the back of the PA cage. Two screws to
mount it at the top and a tie wra

thereto.

are SUPER quiet fans. I can take a picture but used a small rectifier
and cap off the filament supply..just like the T4X. The fan mounts with
double sided foam tapeover the slot between the rear plate and the power

Hi Paul,
I used whatever
The results with this third (and final---I promise!) test were most
interesting (NOTE: for comparative purposes, I have
square-bracketed---[ ]---the changes observed at the very same time
intervals in the FIRST test, at the end of each observation line).
