I'm looking for a schematic of the Heresy Type "C" crossover. I havee a pair of 1974's. Specifically interested in specifications of inductor (labeled "2133") and autoformer (labeled "T2A"). Any help appreciated. TIA

No code is visible on the woofer and the PWK medallion is on there pretty securely, so I'm not going to try to remove it. Both speakers have the K-22-E woofers.

Woofer is labeled K-22-E. Side view of woofer magnet is D-shaped. Crossover appears to contain two capacitors (2uF and 1uF, both 600 VDC), one iron core inductor (labeled 2133), and one multi-tapped transformer-like device labeled T2A. Handwritten in the inside bottom of one box: "1/22/74, CM".

I'll have to check the woofer again, but the crossover is "Type C".

Picked up a pair at an estate sale. Type H-DR-12, Serial # 9M147 and 9M148. Listening to them now and they are very pleasing. Interested in their history and whether there are any well-established recommended modifications. Seller said that they were approximately 20 yrs old. First pair of Klipsch's for me. TIA.
