Yes.

It's a small trimmer pot, about the size of a dime, that is mounted on 
the main board.

If you can't find it, e-mail me off list. I have one with the lid off 
waiting for some parts after my lightning strike. I can look at it and 
give you better directions as to the location of that control sometime 
over the weekend.

Anyone know if there is a voltage adjustment inside the Astron power
supplies?  I have a 35 amp supply that may need some tweaking. 
Thanks.  Lou
