 TEST - Tektronix 2712 
- Here is a Tektronix 2712 up for grabs. It is in what would describe as excellent physical condition. I recently took out the old coin cell batteries and replaced them with new high quality replacements. It seems that the 200Hz RBW filter may need some adjusting/troubleshooting. It can’t pass two of the amplitude normalizations because of this(I think). I was recently gifted a HP unit and would rather spend my time fixing radios and not my test equipment. It seems to be operating well at all other RBW settings. Frequency accurate is spot on and i normalized it with a gps source.
I would be interested to see what kind of trade offers people would be willing to send my way. I like test equipment and old tube radios, what do you have?
