ONE FANTASTIC LOOKING VINTAGE AR3, AR3A MAYBE LARGE WAX CAPACITOR. ORIGINALLY HAD A 150uF, AND A 50uF CAP ENCASED IN A BLOCK OF WAX. NORMALLY THEY LOOK REALLY NASTY WHEN YOU RESTORE THESE. THIS ONE LOOKS PRISTINE. ALSO INCLUDED ARE COSMETICALLY EXCELLENT BRACKETS WITH SCREWS. AND ALSO INCLUDED IS THE FOAM/RUBBER LIKE INSULATING PAD THAT WAS USED BETWEEN THE WAX CAPS AND THE BRACKETS. I GUESS IT WAS THERE TO REDUCE ANY RATTLING NOISES. THATS WHERE ALL OF THAT BLACK STICKY CRUD COMES FROM WHEN YOU RESTORE THESE SPEAKERS. NO BLACK CRUD/STUFF ANYWHERE. AMAZING PLIABLE CONDITION FOR BEING THIS OLD. I MEASURED THE IMPEDANCE OF BOTH CAPS. THE 150uF CAP MEASURED 180 uF, AND THE 50 MEASURED AROUND 60uF. BECAUSE OF THE OUT OF THE HI READINGS, I LISTED THEM FOR PARTS REPAIR. THIS WOULD BE PERFECT IF YOU WANTED TO RESTORE ONE OF THESE SPEAKERS FOR ORIGINALITY, AND APPEARANCES. PS, THESE PARTS WERE PULLED FROM AN UNMOLESTED AR3A SPEAKER. REASON I PARTED IT OUT WAS THE CABINET WAS BADLY WATER DAMAGED AT THE BOTTOM OF EACH PANEL. THE ORIGINAL LOOKING PLUMBERS PUTTY SEALANT BETWEEN ALL DRIVERS AND CABINET WAS STILL SOMEWHAT PLIABLE AND THAT THIN BEIGE LAYER OF PAPER (forgot what its called) BETWEEN THE WOOFER, AND WOOL INSULATION WAS IN MINT CONDITION. AND THE ORIGINAL TW AND MID POTS WERE IN PERFECT WORKING CONDITION.
