Just finished my latest little project. I occasionally listen to Rush while puttering around in my "guy room." Have been using my FT-991, but it struck me as kind of silly to put hours of use on that expensive rig just to listen to broadcast AM. I recently learned of the Echophone EC-1, and as I liked the utilitarian WWII style, I sought one out for a rebuild project.
Online sources say that the Echophone was one of the few radio sets which was allowed to continue in production during the war years. This was both because it was a Government purchased item, and that as a "morale radio," the war news it brought into homes and businesses was deemed worthy of the use of material and production resources. The "Commercial" designation right on the front of the set was supposed to erase any suspicion that the hardy, battleship-gray little radio set might have been purloined from military stores. A long-running series of advertisements in the magazines of the day featured the Echophone being used in exotic locales by the fictional Private Hogarth.
I picked this one up on eBay, and as it looked quite clean and unmolested, I wondered if I might find it all original on the inside. That didn't prove to be the case, and although most of the original wax-dipped paper capacitors were still in place, there was a newer gang capacitor and a solitary "orange drop." I wonder why someone started to put this back into service and then stopped. Was there a fatal flaw that I wasn't smart enough to spot?
So I ordered a pig pile of new caps, as well as replacement resistors for those which seemed to be out of tolerance. Here's what we pulled out:
This is a transformerless set, meant to run on AC or DC, and they are known to be a real potential shock hazard. Several online sources gave good, detailed info info on making these safe, and I performed those steps along with the other work. Here it is all complete:
Speaking of online resources, if you have any interest in modern or vintage radios and electronics, you really need to give a look to the great videos put out by Paul Carlson. He has a great detailed overview of rebuilding and aligning one of these units, as well as a host of other interesting topics. I've learned a ton from watching these. Google "Mr. Carlson's Lab."
Before I started playing with tube gear, I presumed that tubes must be fragile little creatures, in need of constant replacement. These have been in use for some portion of the last 75 years, and had just endured a bumpy, cross continental ride in the UPS truck. Is there any chance they will work?
Well, today was the day to find out. I plugged the Echophone into my newly made dim bulb tester and powered it up... and... NOTHING.
Where had I gone wrong? Hey, you don't suppose... I slid the standby switch from "off" to "on" and the radio leapt to life!
The Echophone isn't a handsome cabinet radio like so many others of its time, but I happen to like the quirky, battle ready look, and hope to enjoy it for a long time to come. Hey Hogarth, thanks for the recommendation!
Cheers... Jim
