Hey, I built an AA-29 for my very first stereo, with the walnut case, heh! (Built a second one for my sister.)That is a cool looking little unit. It kind of matches my Heathkit -29 stuff.
I presume the Phase Shift inverts 1 or more speaker outputs - to give a more enlarged room atmosphere where sounds will be more echo like.....better than converting a straight 2 channel to drive 4 speakers.
The downside is that sometimes it may sound "hollow".
Does anyone know what the phase shift function does?
Sorry for the late response, Jim. I just saw this.
...My quad system is all based on these units. My original AA-29 is the center used to select sources and modes. The extra auxiliary input really comes in handy for this. The other AA-29s are slaves to drive speakers and the tuner and amp sections of the AR-29 are also used. I have four Advent stacks in the system and each pair is driven by it's own amplifier. SQ, QS, and other matrix or stereo records are played on a BIC 1000 using a Sony SQD-2050 decoder and CD-4 records are played on a BIC 980 (bought from Heathkit at the same time as the AA-29) through either a Panasonic SE 405 demodulator (magnetic cartridges) or a Technics SH-400 (semi conductor/strain gauge cartridges).
...Do you still have and are you using your Heathkit?
