[RTTY] Alpha 89 question

[Bill]

Before each contest I use a very very strong vacuum cleaner on all my 
amps and rigs.
Clean all intake and exhaust vents
I clean the fins on the tubes also.
You can't believe how much dust can build up in a month.

Now I hope I don't have to tell you to power down any amp/rig/computer 
before cleaning.
!!! Warning!!! pull the power cord out of the wall socket before taking 
any covers off of Amp or power supply to clean.!!!

I also do this for my computers also.

Now if I can just vacuum the cobwebs between my ears, I might actually 
.... nah, too old for that to help.

After some head scratching I had beefed up the air debit of the auxilary fan and the problem went away. It came back though last weekend and we were unable to make it work for more than 5 minutes before it would again go into WAIT state. What happend then is that after sitting pretty for a day or two the amp starts working normally unless I use it without the aux blower on for a long period.
