This instrument has both 1/3 and 1 octave bandpass filters.  The frequency range extend from 22 to 45000 Hz.  It has an internal transistor output amplifier that can be powered from a standard 9 volt battery.  It has a filter advance mechanism and may be remotely switched through all the filter settings. This particular unit has been dropped in shipping with rather severe consequences.  Eleven of the thirty three filters are broken. This unit is for parts only.   It does not work properly.  No returns on this one.
This unit was inadequately packed and then dropped in shipping. Very little damage is visible outside the case, but internal damage is substantial. There are metalwork problems like a bent chassis and bent mounting rods. The metalwork problems are small compared to the electrical ones. Eleven of the thirty three filter sections are broken. I used an ohm meter to discover that the damage was always the coils. They have opened internal to the coil. The coils were custom wound for B&K and this unit went out of production in the early 1960's.Again, 1/3 of the filters are broken. Direct replacement parts are not available. This unit works on the other filter sections, but the way this unit is used requires all the filter sections to be functional.
