I have a Blaupunkt BEA-120, an equalizer-booster from an old Porsche's factory system. I'd like to bypass the amplifier stage (the ICs), and use it as an equalizer. Can this be done?
I really like this unit, it wasn't bad for a booster (has a bigger heatsink than some small amps), but it looks like the ICs are blown anyway, due to a speaker lead short. The band's frequencies are really useful, and it has a glass-epoxy PC board! It's a quality component.
Any help would be most appreciated
