Re: [Drakelist] TR-4 Noise Blanker question

[Garey Barrell]

Hi Don -

I suspect there IS a market for a functionally identical NB that would 
plug into the 34-PNB socket in the TR-4C.  The board wouldn't be 
difficult to produce, as it is a single-sided one, and could certainly 
be "down-sized" with some SMT parts.  It's not a particularly tricky 
circuit, and no really oddball parts, so shouldn't be hard to 
reverse-engineer.

The last TR-4 and all the TR-4C versions had the socket for the 34-PNB.
The earlier TR-4 versions used the 34-NB wired-in style of the NB.

There are a few different PCB layouts for the 34-PNB. One has the
old brown phenolic material and there are at least 2 versions of
the green fiberglass boards.

Re: [Drakelist] TR-4 Noise Blanker question

[Byron Tatum]

Hello-
I have been following this thread on duplicating the Drake TR-4 noise 
blanker closely. Actually, I have been thinking of trying to do so myself for 
some time, and have been communicating with certain folks regarding such. I was 
hoping to find a scrap noise blanker to strip the components from, namely to 
unwind the torroids (to get winding info)  and then to measure permeability of 
the cores.
As far I know there is no difference between the different versions of the 
noise blanker for TR-4 series, regarding the PC board itself. I have compared a 
later 34-PNB PC board with an early 9-NB PC board and the circuit is the same.
There is some confusion regarding the little PC board that was supplied 
with some early 9-NB noise blanker kits. I believe the confusion stems from the 
different impedances of the IF filters and their matching transformers. Some 
early TR-4's had the soup can IF filter, wheras later ones went to the nice 8 
pole units. The soup can has around 2200 ohms resistors across matching 
transformer winding versus about 470 ohms for the 8 pole units. The little PC 
board was for matching into these, but is really not needed as was later proven 
out.
I have seen all the various noise blanker installs, from the early 9-NB one 
using the added switch concentric with the PA Tuning control, to wired in 
TR-4's with front panel switch to the plug-in 34-PNB. I have removed the noise 
blanker (from parts unit TR-4's I bought) from several early-type installs with 
the little matching-PC board, then re-installed these in TR-4's but minus the 
little PC board. I installed one of these blankers in my TR-3 with good success.
I would like to participate in an effort to duplicate the noise blanker PC 
board. The PC board is the main problem to me, as I don't believe there is any 
artwork surviving out there. It appears we would need the help of someone who 
could produce the artwork, using an existing board as a guide. As far as 
getting the parts and construction I believe that could be done OK.
So here is my two cents on the thing.

Thanks, Byron WA5THJ
