[ARC5] Solid-state battery tubes...

[Tim]

Good stuff Ken - very clever packaging!  Now where did I put all those dud
glass tubes..
Wonder how he sawed the glass parts apart.  Also, hope he added a small LED
to simulate the filament load (I'd use a tiny Green one just to mess with
my head!)  Would greatly appreciate a performance report!

Fortunately my R-1004 is still going strong with the original 1L6 but it
does have a lot of mileage on it.  Apparently the Transoceanic guys have
captured all the 1L6's, at least they are not going into guitar amplifiers
(yet)... (But they *do* have that late-1951, early-1952 warm vibe......)

Someone just mentioned connecting a Q-5er to the receivers' audio output -
enough IF leakage thru that circuit to drive the Q-5er.  Cute!
Thanks..Tim
