It's a 100 page Word document which I will distribute via email once I
get a list of names together. You can print it or file it as you wish. I
also have the 80 or so page RSGB Receiver document by G2DAF as a Word
document for those interested. They are both on my CD but occupy too much
space on the web site. They are both great pieces of info to have if you
are working on quality tube receivers. 

Right now, a friend of mine and I are working to improve the Drake 2B
receiver. Triple conversion without the typical string of IF stages. If
you can find one cheap, buy it. I've always thought the 2B was a great
example of a commercial tube type HF receiver of the early 60s timeframe
which is physically compact, sensitive (0.5uV or better), selective (good
permeability tuned passband), simple slide switches, multiple Hi-Z AVC
points, copper plate chassis (there are no "bad grounds" to tube
sockets), screws vs rivets, low power (less than 40W), "low" voltage
(less than 180VDC) and uniquely efficient design (have you seen the
outstanding use of vertical terminal strips ? super simple graticule
adjustment, etc). It also offers the distinct "ease of use" advantage of
bandswitching and crystal converters. Still an excellent design in this
day and age. Maybe some of you have some input on improving that design ?
