I'd rather not risk another flameout and the capital committee has just given approval to commence with replacement so I am going to figure out another way to power the two subs.
The pictures looks like a power supply board fried? Did it fry itself or did the output device(s) short and take it out too? I'm surprised it's non-repairable or a newer Ice amp isn't available?
The crown amp might be nice, but how are you driving the subs? If from a pre/pro or HT receiver that covers the crossover and level control, but;
From the Maestro manual,
"Miscellaneous:
· A limiter and current sensing feedback circuitry protect the driver from being overdriven and reduce distortion.
· The discreet outputs of the amplifier deliver over 500watts RMS to the woofer with extremely low distortion.
· A temperature switch monitors the output devices. In the event of excess heat the switch will shut down the
circuitry to prevent damage. Once the heat sinks cool the power will be restored. Because the electronics
have been designed and ”tuned” to the woofer and cabinet, the Maestro offers incredible performance in a
relatively small cabinet."
I would feel better with some of the protection circuits, esp the limiter, but I'm not sure how to duplicate them, maybe someone will chime in ,or the bassplace here or a DIY site where they're building subs; Like Hometheater shack for one would know more?
Come to think of it Hafler 280's were run in bridged mode for sub amps and worked quite well!
Some thoughts,
Keep us updated,
