David Bogen 2x LA1 vintage mic preamps & PSB POWER SUPPLY 1958 STUDIO CONDENSER

Description

Super rare Bogen mic pre's with hi-z or low-z capability.  I will eventually set these up snd test them, but I wouldn't wait for that.
Unlike modern "tube mic pre's" these are the REAL thing with power and plate voltages near 300 with a 600 volt send. These are the real deal and super rare high end preamp/line amps by one of the best no nonsense tube amp manufacturers of last century.
Untested but will test soon, but built like tanks and presumed funtional, with complete working matching transformers for input and output. Inside i can see connections for 2 conductor hi-z and 3 conductor xlr style. All three units date from 1958 and were part of an early pro sound rig, as add ons for recording and amplifying miked and line inputs. Items are sold as is for your own use, set up and or repair/restore. Thanks for looking!
