HELP !!
I am looking for a schematic and information for a Navy ship TAJ-19 transmitter
that I recently acquired. It was made by General Electric in 1944 and uses one
861 in the Final and three 860's. Any leads on where I can get information for
it would be most helpful. I have found some inform
There have been some comments about H.V. diodes not testing but seem to be ok.
I assume that people are testing them with the diode function of a digital
multimeter.
Typically, a H.V. diode has a number of diodes in series within it which makes
it have a higher voltage drop than a normal diode
There has been alot of discussion regarding electrolytic capacitor leakage.
Here are the "official" specifications. The JAN-C-62 specification addresses
the maximum acceptable allowable leakage for electrolytic capacitors. (There is
also an EIA specification but it is the same as Jan-C-62). The
I agree that substituting a 6V6 for a 6L6 is quite a stretch. I am an active
and founding member of the Tube Collectors Association, Inc. Over the years
the topic of tube substitution guides has been discussed within our group.
The general consensus is that there are numerous "tube substitution
A few days ago, I requested information on the Stanwyck Winding Company. A
gentleman contacted me by email outside the reflector and stated that he had
worked there. Somehow his email got dumped before I could respond. I would
appreciate another contact from that gentleman so I can correspond. Than
Hello Guys:
Do any of you have catalog information on inductors and related products
manufactured by the STANWYCK Winding Company of Newburgh, New York? I am
looking for information on their products manufactured during the early 1960's.
Thanks, Bob K2GLO
Hello Don I would like to purchase your Coil Forms and receiving coil Box
($140) and the box of and Mini-Ductors and Air-Dux coils ($75). Please tell
me the total to 97520

I got excited when I found both a Sangamo 0.0001 and a .00015 Mfd. 2500 wdcv
type A2 capacitor in the parts bin. However when I tested both of them they
were both shorted. What a bummer! I also found a Cornell-Doublier type
9LSA 0.0001 Mfd. at 2500 wvdc that looks physically identical to t
Thank you for the detailed information. I appreciate it. My friend is
sending me copies of the Handbook article. It is great to have a responsive
group like this with so much knowledge on tap.

I have a bunch of 803's. In the past, I have seen modulator articles
featuring triode connected 813's. Physically, the 803 also looks like it
would be a good candidate for the same application. Has anybody tried triode
connecting 803's for a modulator? If so, what were the design parameters did

I have a 2-inch monitor scope that was built from a schematic that appeared
in the 1950 ARRL Handbook, page 490. You might be able compare your circuit
against that schematic and get a "ballpark value" for the capacitor you
seeking information on.

Hello Larry and all:
Larry's tongue in cheek comment employing 866's as a linear amplifier tube
prompted me to contribute the following: Certain full-wave rectifiers can be
configured to amplify or oscillate. I have built audio, Hartley and Simpson
oscillators using only 6AX5GT's full-wave rectifi
