I picked up this vintage (1972) B&K Precision 277 Multimeter at a local ham swapfest. The seller was cleaning out the inventory of a deceased relative.

You might ask, Why waste time on an outdated analog meter that only has a 2-3% accuracy spec? Answer: The big analog movement is good for AM/FM IF peaking alignments. It is also good for testing to see if a pot tracks smoothly. You can still buy new analog meters, but if you want a really nice one the price is quite high (Simpson 260, etc.). So, this is simply my way to get that big, well damped, analog meter movement at a very low cost.
