Carlspeak Posted September 7, 2012 Report Share Posted September 7, 2012 I recently transferred the drivers and crossovers from a pair of 3a cabinets that were in poor shape to a pair of very nicely restored AR3 cabinets. The 'transplant' included the addition of new caps and modern, gold plated binding posts that fit nicely flush with the back of the cabinets. Note in the crossover picture, the 150 uF cap is not shown because it was attached between the pos and neg terminals on the woofers. Also note the 1/2 ohm cast resistor in place of the original thin wire following the 50 uF NPE Erse cap. The original 3a inductors were salvaged and placed as best I could with room available. The large #9 coil wouldn't fit well in it's normal spot above the mid pot. The proximity of the 3 coils did not affect the finished performance. The pots shown are 16 ohm factory replacement pots that came in the 3a cabinets. Link to comment Share on other sites More sharing options...
