Dentron Fan Speed?
 

Have a Dentron GLA-1000, works great, but the fan speed varies fron a
whisper to double the loudness. Any ideas? Please assist. Email direct
.

I have a commercial license with radar endorsment fron the USAF,
although old I have always kept it current. Thus I was also wondering
if any of the experts out there would be interested in building a tuned
input board (10M) and adding glitch protection on this great old amp
for me. Tubes are good and original.

I am a disabled Vet and its hard to do these things.
