Beautiful Phase Linear, Uni-Sync and Bisound power amplifiers...Misc tuners, integrated amps and preamps...
These 612C clones have been in heavy use the last week. I admittedly have no experience with Altec cabs before. I have them set up roughly 2ft off the floor on another pair of older Altecs that came with the lot. The range and response is startling. It's a flat pass for sure and different recordings from different eras, and on different formats, all have a very unique and individual playback character.
I appreciate the analysis of the cab and crossover construction. I am waiting on a letter of pedigree from the owner/builder that may shed more light on their history.
Thanks again and stay tuned!
