This page illustrates several of the vacuum tube projects that I've been recently working on.
You can probably guess that I'm a big fan of Alfred Morgan's series of books such as:
"The Boy's Second Book of Radio and Electronics" which I had received as a Christmas
present many years ago.
I felt compelled to build some of these old projects (again).
Although the Morgan projects would work just fine without it, I've added an isolation transformer,
fuse, and 3-line grounded AC cord for safety's sake.
Hopefully, I'll add more skizzies to this page soon.

A recent addition is the 1934 Doerle Twinplex as illustrated in T. J. Linsay's book.
I've just completed this set (Nov 16, 2005) and it *really* works well.  I can't wait
to wind some additional coils for it!  (I've recently disassembled it to paint it.)

My newest additions are the Lindsay Grid Dip Oscillator and the ubiquitous Allied Knight Kit Space Spanner.
I was able to reproduce one coil to date by using my GDO and Gingery coil wider.  What a blast!

I've just added my first heterodyne receiver for 80 meter band.  What a difference!  The tuning very sharp when compared
to the regenerative radios.  Although it is another "primitive" design, it really works well!

I may try winding some AM/BC coils to see how it compares to my first radios.

New addition August 27, 2006, the "Doerle Signal Gripper".  This is a nifty 3-tube regenerative receiver that features
a tuned RF-Amp, grid-leak detector, inter-stage transformer, and audio amp.
I've yet to engrave the front panel, but that's next!

And after all that, I'm going to have to re-layout my WEB page to show more details!
