Thiel Owners

Thanks, Tom. I’ve never had an opportunity to listen to DR-series Classé amps. I think my first Classé amps were the first post-DR generation. They tilted to a warm sound. Maybe that agrees with your comments.

My current-generation CT-2300 has a much more transparent and neutral sound to my ear. From what little I understand, its design is fairly distinct from previous Classé series, including the DRs.

Good to see you. Thank You for sharing a bit of Classe' and Thiel history.

Happy Listening!

I have measured the woofer coil, seems to be the same as on the diagram, wire is 1.8mm in diameter, coil size is 55mm outer diameter with a height of 33mm.

holco - your crossover seems to be a transitional form. (I am learning via reconstructing evidence.) Your coil values are those on the point to point Lex-built boards; and they are well-wound. Your caps are polypropylene which also points to Lex-built. It seems that Thiel-Lex must have transitioned to printed circuit boards, before eventually sending manufacture to China or otherwise diminishing parts quality. What are your serial numbers?

So, you have original / good-quality parts. Your coils are likely to be best of form; don't swap them unless you go to ERSE foils in the same gauge (DC resistance equivalent). Beetlemania's previous advice sounds good to me. He / we will know more soon. I am sending his parts kit today for a fairly full-bore upgrade test-build.

serial numbers are unreadable :-(
