I already had a monster blower on hand when I put my YC-156 amp
together. I drilled a hole in the wall, and ran the cooling air
thtough a 10 foot hose from another room. I hear no more noise
than
the cooling fan on my PC makes here in the ham shack.
### I learn something new every day ! I never tried remoting a
blower. I had been told that a lot of the noise was from the
actual airflow through the tube itself, so never tried it.
### Never had any problem remoting the RF deck/Hv supply either...
since we can see the wattmeters in both places... and easily tune
the amp in the other room. With variable 0 to -10 vdc in the
remote location... fed back to the ALC jack on the xcvr... and a
footswitch/wattmeter in both locations... it's easy to tune the amp
up. Just run into another room... adjust drive level... tweak
it... once the numbers are all written down, it's a moot point
anyway.... just change bands and dial by the numbers.
My shack is really small 8 x 10 x 7.5' ceiling. ...... the
concern with a remote blower would be cooking the shack with too
much hot air !!! ... even in winter.
### with a bigger room.... I can see the merits of a remote blower
[s]. With the entire amp remoted.... in summer time, one can
exhaust the hot air outside.... and in winter, exhaust to the
inside.
