You are bidding on a PDF collection of high-quality scans of 78 Sound Level Meter-Related manuals from Bruel & Kjaer, the respected audio and acoustics test and research equipment manufacturer in Denmark. Anyone that has worked in audio and acoustics is familiar with this company and this equipment. Here is a chance to get a (somewhat random) collection of service and instruction manuals for part of their product line from the 60's and 70's. These devices remain the mainstay of the acoustics industry even today. There are 42 instruction manuals on Sound Level meters and 13 service manuals on Sound Level Meters. Disc also includes the filter units that are designed to connect directly to the sound level meter by screwing on to the bottom of the meter and connecting electrically through a shorting bar. There are 7 service manuals for filter units and 14 instruction manuals for filter units.

These are older manuals - from maybe 1964 to 1976. Some of the older devices are vacuum-tube only. Some intermediate devices are hybrids with both vacuum-tubes and transistors. Sometimes there are several versions of a given manual - this is because sometimes the manuals only cover certain ranges of serial numbers and were revised several times. For completeness, all the different versions I could find are included. They are not of uniform quality. There is a full-text index over all the manuals, so you can do a search for, say, "Fletcher-Munson" and get all the references through all the manuals

Auction is for ALL 78 MANUALS on one DVD-R Disc.
