[R-390] Sync Det II

[Perry Sandeen]

List, 
 
The ski that Al sent me from the QST is the one I
was thinking about and I started re-drawing it with photoshop elements as a bit
image.
 
Several hours down the road working on the
schematic I decided to see what IC’s were used.
 
Then I discovered a major problem.  They all seem to be “unobtainium”.  The one source listed is out of business.  My search on Ebay didn’t show anything except
two surface mount NE602 pieces.  I didn’t
follow up on the IF subsystem that was used for availability. 
 
Unless someone has sources for these IC’s this
becomes a dead end project unless some on the list is able to redesign it with
available components.  Redesigning it is
far beyond my skills.
 
The project needs two NE602 and one NE604 FM IF
subsystem IC’s.  If anyone wants to
search them out and they are available at a somewhat reasonable price the list
would appreciate the info.
 
Regards,
 
Perrier
 
P.S. If anyone is interested I have a 20 gallon SS
single column still for sale.  Shipping
weight exceeds 100 pounds in two boxes.  Requires
two 220 volt water heater heating elements and control circuit, not included.
