To Anyone in the know... Please tell me about the 1569A Amplifier. It seems to be a surprisingly high powered amplifier @ 80W per mono-block. It surely must run in Class B. Is this the case or does it run in some form of AB? I kinda think it would have to be Class B; just wondering if anyone knows.
I would love to hear all your thoughts on it. Is there any "fluidity" to be had with this amp, or is it a hard core & hard edged audio signal power provider that was used in cinemas??? ....where & when back in the days these amps were in vogue cinemas weren't known for their "hi fidelity"
I know about the limited bass response. I am tri-amping and am only interested in using it for midrange or treble reproduction, and would not be using it below 500 Hz or higher. I would even make use of and switch on the amp's 250Hz filter for that extra safety.
I am looking forward to your comments regarding its use for mid or treble reproduction. They would be driving Smith horns (full sized or minis) with JBL drivers, 2445 or 2447 if mid, 2402 if driving tweeters.
I'm even thinking of 'trying out' the 70V tap to see if the amp operates as a "constant current source" in that manner on its high impedance output tap. I think I may need to alter the feedback circuit slightly to achieve this however.
