I do have a set of drawings but they are pretty shabby and really won't 
photostat to be really useful.  The best way to fix that problem is to
do the following:

1) Replace the regulators.

2) Solder them in.  Do not use the sockets.  The sockets have caused
   90% of all failures on the RFD-40.  

3) Check the rectifiers and replace if necessary.

If you do all of the above It should work for another 5 years or
more without trouble.  

As a note:
	The RFD-40 has a jumper on the board that will allow the
Atari to see it as drives 5-8 instead of 1-4.   Kinda neat if you
want more online storage.

If all of the above fails then email me your name and address
and i can either exchange your old controller or repair your
old one.
