Measures 10 x 5 x 6 and has all the knobs on the front and the pointer moves when the knob is rotated. Item powers on and the green light illuminates but that was the extent of our testing so it is offered as~is for parts. This is a vintage Heathkit Model SG-8 RF Signal Generator.

THE HEATHKIT IG 37 FM STEREO GENERATOR MANUAL MANUAL
The 4-page manual includes a pictorial.Step-by-step instructions, picture of the final project, and a schematic of finished attenuator. This will give you more options of using it and the printed attenuation levels printed on the face can now be used to determine sensitvity and s/n measurements. This kit of parts gives you all of the resistors required to re-build your Attenuator for a 50 Ohm system. This allows you to work with up to a 1 Watt signal source continuously, or we have had good luck going as high as 5 Watts intermittently. Newer 1 Watt resistors have the same size as the original ½ Watt resistors.
THE HEATHKIT IG 37 FM STEREO GENERATOR MANUAL UPGRADE
We decided to upgrade all of the resistors to 1 Watt. This makes all of the values of attenuation printed on the face accurate. It had been suggested by a few of my customers to create a simple kit of resistors to make it more convenient to do the modifications from 75 Ohms to 50 Ohms. Maybe you have even used it, but the switches were not accurate because of the difference in impedances. For that reason, if you have one of these nice little attenuators, like me, it has probably just sat on the bench. But it seems that doing the calculations, finding the required passive parts, ordering them, and testing the final product is a lot of trouble to go through. It is possible to re-build the attenuator with different value resistors so it will operate with 50 Ohm equipment. The only issue is that it was originally designed for a 75 Ohm input and output impedance. This external box allows attenuation from 1 to 70 dB in 1 dB steps.

Or have seen these at various Ham swaps or auctions. This attenuator was then passed on to the IG-57A and the IG-5257 in later kits. Heathkit 70 dB Attenuator Mod Heathkit designed a very nice external attenuator. Data Professionals Main Page Providing support for legacy Heathkit products.
