I am not trying to be unkind when I say this; the Bogen stuff was not designed to have audio quality for even semi pro recording. It was designed for PA & background music systems. Altec equipment was designed to a higher standard, high quality sound reinforcement; with the exception of their microphones & 250 SU & 350 mixing consoles. I was the sole technician for an Altec Engineering Contractor, also sold & serviced Bogen for PA & bar sound systems, 1958-1965. Would not recommend this piece.
Okay, Bill. You’ve got me curious now. The 250 SU had the 458A/459A amps in it, didn’t it? We’ve talked about those a few times (those crazy transformers) and nothing about them screams less than high quality sound.
Maybe you’re inferring something about reliability? Hot tubes and thin transformer wire?
Would love to hear about your experience with this console.
