This is a "recap" of another posting I made, but I decided to break it out and give it its own subject thread... Thanks for the help!...
After an intensive recap, resistor replacement, and rewiring, my 37-650 is up an running...
Well, I've had her up and running for a couple hours now: while she is reasonably volumned, I am wondering if she may be a little quiet- and if so, how would I go about rectifying this? I found(before I added a rough wire antenna along the wall) that if I touched the top terminal of the 6A8G Det-Osc tube, the volume would pick up. With regard to the tubes, I replaced one of the two 6F6G tubes- and the other is a 6F6GT. And I seem to recall it(the GT) being a touch weak. Could this be the cause of lower than optimum volume?
All switches seem ok- I get nice tone change with the tone control.
AM and the first SW band seem fine- couldn't find anything on the top SW band, but I will try later in the day. With the antenna(just a long wire attached to the 1 terminal, and running between 6 and 8 feet high, about 30' long) in place, I get all sorts of stations- I found a Buffalo, NY station about 1520, which plays old stuff. I am outside of Philadelphia, so I know I'm catching a good signal.
I am pretty sure my Shadow Meter is not operating properly- I read through the information on Chuck's site, but I see no part which would operate as described in the way of a mgnetically induced flap- I am of the opinion it has been removed from the unit for some reason. All I get for display from it is a nice bar of light above the dial.
The dial lamp seems to be operating nicely- I like the way it back glows and has the well defined indicator line.
Anyway, any suggestions to how to inprove performance greatly appreciated.(All caps, bakelites, resistors, most wires, replaced or rebuilt)
Thanks!
