I figured this would be a good time to show a Clemens SG-83C signal
generator. This rare bird runs from 50kHz to 54MHz and is completely
solid state and can run on an internal 9-volt battery or from the AC
line. These date back to the 1960s.

The attenuator system is a bit kludgy, but it is closer to being
quasi-lab quality compared to service shop units. The alignment
is done through the front panel, no dissassembly required.
They are rare, but show up occassionally. I had three at one
point, but I am down to two. No, they are not for
sale.

I can recommend this excellent signal generator. It produces an essentially clean sine wave on all bands, and has the very desirable feature of battery or mains operation.

The designer and manufacturer of these splendid instruments posted a message on the ARF last year:

To further show what a small world this has become, another ARF member mentioned acquiring from Mr Clemens a Measurements Model 59 grid-dip meter that was used in the development of the SG-83 line:

Hi everyone. My name is Forest and I have been searching for someone who has these model signal generators. I also have a SG 83C signal generator. I am not a radio expert but I have not been able to find much information on this model. The significant piece of information i have discovered is that this is a rare model. I also have not found anyone interested in selling thiers. I however am interested in selling and would like to ask the people who posted on this page what they think of my price. I am considering posting the radio on ebay for a starting bid of $1000. The model I have is simular to the picture displayed at the top of this post with the name and model printed on top. The difference is mine has all the face plate screws and the serial number is posted at the top right of the unit. The serial number is 496. If you want more information or a picture please respond.

I three of those units at one time. I sold one to Avery a few years back. I would put the value at under $200.00. I'd certainly part with a second one for that price! They are stable, and are pretty reliable, except I have had to replace the J-fets in two of mine. Their best feature is being able to be powered from a nine volt battery for field use.

I valued mine so much I brought it with me when I moved to England this year. I was impressed with the accuracy & stability of the unit. While it wont run on 230VAC here the 9 volt battery lasts a long time.

Second Pete's and others' endorsements. My only small complaint is that I wish the AC connector was on the back and not the front, where the power cord likes to get tangled up with test leads, screwdrivers, lengths of solder, etc. (I also don't like cheater cord-type plugs, but that's no big deal.)

I just found one at a garage sale today. Came here to find out more about it. Good find I guess?

Absolutely, if the price was decent and if it works. I wouldn't want to troubleshoot it.

It works. I just haven't put any stress on it. Initial inspection of the interior looks clean and unused to be honest. I'll spend some more time looking into it, I suspect it sat in the basement for a long time. Some rust on the outside where some scratches were but it's shockingly nice on the inside.
