Easy Sandy - you should be able to look him up via the QTH lookup
services available on the web.
I have a number of them listed as links from:

I hope that helps you find him!

Mystery solved! So that's why the old timers used a dish pan with a grid
leak. Years ago listened to a 75M operator (Ronk W4MYJ) that always said he
was running a pair of 807's submerged in a bucket of ice water with a "dish
pan for a grid leak". 73 Jim K4CGY

One of the "apprentice" jokes of yesteryear
was to send the kid out to the radio store
to buy a drip pan for the grid leak, but I
always thought it was just a gag!

Hi, all:
Don't know about the dish pan, but I've heard from many a source about
salesmen back in the twenties who promoted "drip pans" for grid leaks.
Helped to keep things from needing more frequent maintenance, don't you
know? I suspect those peddlers were perhaps the same ones who made their
living as itinerants who, for a fee, would charge your lightning rods.

Subject: Regen Receiver in November?
Hi Glowbugs
if October was Regen Month, what happens if I want to build a regen in
November.....
I had a nice BA QSO with Art WA5OES on 3.579 the other week. Art got to
telling me about his regen receiver. By the time Art finished
describing the receiver, I coundn't wait to build one. I dug out my
C.F. Rocky Regen book and started reading it. I had only glanced
through it before. Read it this time. Hmm, so thats what a "throttle
capacitor" is.
Art then mailed me the design information on his receiver. Thanks Art!
Its a 1934 Globe Trotter from an article by Dave Ingram Feb 1990 CQ. It
uses two '30 tubes with a capacitor throttle, 45 volts dc.
Art mentioned that there was a few problems with the original article
and some of the fellows on the list recommended some changes.
Why is the antenna trimmer variable capacitor value recommended to
change from 100 pf to 3 pf? Does is 3 pf really enough to tune the
antenna. Maybe it was changed to reflect different number of turns on
the grid coil. Three pf seems close to zero pf.
I would be interested to find out what other folks used for the coil
turns for the different bands.
Thanks much,
Scott WA9WFA, St. Paul Minn
