I have a copy of the 34-PNB manual on my CD. There is also a hi-res
color photo of the 34-PNB board (both sides) with the transistors id'd
and a table of voltages, along. The 34-NB manual has the circuit and
Drake's photo of the component side and installation procedure in a TR-4.
The circuit is the same in all of them, and the basic circuit topology
is the same all the way back to the 9-NB.

Pete,
I gave Garey a copy of the 34NB kit that Drake sold for wired install to the
TR3 and early TR4s. I have the electronic copy somewhere, and I think Garey
has it on his CDs, but am not sure. I seem to remember that it had a picture
of the PC board, so it might be fairly easy to fabricate. About the only hard
part would be any toroids. Seems like it has 2 or 3 of them. I could guess
resonate at the IF freq, but not really sure.
If you are serious, I will try to look up the electronic doc and get it to you.

This may have been covered before; but ... has
anyone ever hand built a
noise blanker using the Drake schematic and installed it in
a TR-4?
