[AMRadio] RE: Yet another receiver update!

[Brett Gazdzinski]

Bacon,
This was a great help!

Looking at some of the web pages, I now get the ratings.

Surplus sales has some good ones, I am looking for a few around
68 and 150 pf.

I bet I even have them in the junk box, as I have a BIG bin
of disk caps, and remember seeing various ratings like n750
etc....
If I can just find the right values...guess I will be sorting
caps tonight!

Looking at their web page, I see they have all sorts of goodies.
Ceramic slug tuned coil forms, bigger ones, some with the
coils already wound!
This opens up the possibility of me building another receiver
using band switching, 7 and 9 pin tubes, and much smaller in size.

They seem to have almost everything you need to build a nice home
brew superhet, coil forms/coils, rf chokes, caps, etc.
They don't seem to have 455khz tube type IF transformers, but
I have lots of those...

Hummm, maybe separate home brew transmitters and receivers
for each band?

What fun this stuff is!

Thanks,
Brett
