?Item Description:This is a non-working B2 section from a Tektronix 455/A2/B2 Portable Oscilloscope. This unit is not working because the custom IC chips have been removed and being sold in my other listings. This B2 section with boards and knobs is being sold for parts and would be great if you need new boards, knobs, or other parts for your oscilloscope.
