Still looking for Hickok 121 Cardmatic cal card
|
| |
Even Alan Douglas has no idea where I can get a calibration card scan for a Hickok 121 Cardmatic. He says that the 121 was not a common model. I'd like to get a scan of the cal card so I can make a card and calibrate the tester. I have the instructions; just need to know what the card looks like. Any help is appreciated. Again, I don't... more »

First Portable Radio
|
| |
Does anyone know who made the first portable radio. I don't mean simply a radio which worked on batteries because many of the earliest ones did that. I mean a radio which was specifically designed as a carry around.

A few months ago, I posted a request for documentation on a Grunding 5089 TB. I'd like to thank the members of this group who assisted in coming up with a lot of information on this toy. The radio has been brought back to life, and has the sweetest, mellow sound. :::chills::: Haven't gotten the tape deck to turn on, yet, and I'm going to... more »

The 6L6 socket spacing on the Stromberg-Carlson 145L
|
| |
The sockets are too closely spaced to use 6L6G or 6L6GA. 6L6GB and GC will fit. I wonder if they anticipated 6L6G and decided they wouldn't accommodate them or just didn't know 6L6G was on the way?

It gives the general public the... more »
