I've always wanted one of these! I recently acquired one from a friend. It was basically in working order, bug just needed a little TLC. I cleaned the controls and switches, and gave it a full alignment. Wow, what a hot reciever! Here's a few vids and photos...
The Sabtronics 2000 DMM was originally a kit form benchtop meter. This unit was built in on of the once-popular TenTec project boxes. I got this from a friend, and set about to repair it.
The DMM was basically functional. The pushbutton switches needed cleaning, it had a bad internal battery pack, the charge regulator had failed, and the front panel needed repair. I eliminated the battery, repaired/modified the charge controller to provide 6vdc to run the DMM from an external supply, repaired the front panel, and calibrated it. Wow, this is a sharp, very accurate DMM with a 10 megOhm input impedance.
My son needed a RF sampler for his workbench, to provide a feed for his frequency counter. I had a home made T someone had built with a trimmer cap feeding one port. I have no idea what it was in a previous life, but it was perfect for this project.
It had 3 type-N connectors. I gutted it, and built the circuit shown below. It was optimized to provide less than 200 mV at any freq between 1mhz - 500mhz. Using adapters as shown, it can be used with feedlines / jumpers with type N, UHF (pl-259), and BNC connectors. The power derating is on my chicken scratch schematic.
This isn't radio, but it is somewhat electrical. In the midst of Christmas fun, the clothes dryer blew up. This is the third heating element failure since 2008. I spliced the element back together and got it going for now, and new element on the way. These things sure don't last like they used to...
