I'm not familiar with the Ramsey 40m reciever kit, so there's not a lot I 
could do to help, Stan.
what you COULD do is call K-Comm, here in San Antonio (anyone know their 800 
number?) and see if they'll make you a photocopy and mail it to ya, if you 
send them a "Self Abused Stomped Antelope ) (SASE)

Probably.  Look in the tuning area of the reciever, right there at the ouput 
of the VFO.  Depending on how the engineers designed it, there's probably a 
'tap', that can be changed to cover a different part of the band... perhaps a 
variable inductor?

As PAul said, that's a good little generic all-purpose op-amp.

They cost, what, maybe a quarter a peice?  Go get a buck's worth, and build 
away!

Abilene, right?
talked to a guy Saturday out in Ozona - his well on his property is down to 
10 gallons a minute, able to be pumped.
