Can any body help me to get a tube position map

I bought an Air Tight ATE-2 from Audiogon, now, I try to replace all the old tubes, can anybody help me to get a tube postion diagram, for all the tube inside the letters could not be seen, and the manual from Air Tight does not indicate all the tube position.
Thank you
contact: They should be able to help you out. They have been selling Air tight for many years.I am sure they'd be happy to help you out..Good Luck...
Also try and track down Tom Tutay in Florida. He's the east coast service center for Air Tight and could tell you. Do a search of his name here and AA and you can probably find a phone number. Good luck!
Here is a picture of the insides if this will help:
