  1. I have rebuilt them and it's hit or miss. If the brass bushings are worn, then no amount of rebuilding helps.
  2. I sent the email on July 13th to the email you registered with. But no worries, you know how to contact us!
  3. We service a wide variety of audio amplifiers; including Phase Linear, Sunfire, Carver Tube Amps, Adcom, Hafler, McIntosh, Pioneer, Yamaha, Krell, and more! Service Base fee: $100 The base fee covers basic repairs to a component to restore its operation. The fee covers up to $20 in parts. If more work is needed, or if expensive parts are required, a quote is submitted for approval before work is done. If the component cannot be reasonably repaired within an hour or two, a quote is submitted right away. If the quote is refused and work was not performed, the fee drops to $50. If the repairs cannot be performed due to lack of information or resources, the fee drops to $50. Most repairs do not exceed $200. If you need a custom shipper, please let us know. We can make a custom box for most models and send it for a small fee. Don't get frustrated over shipping - we will take care of you! Contact Service
  4. We now offer custom brackets to retro fit modern binding posts to vintage gear. So as long as the fitting is done properly, vintage gear benefits greatly from new speaker binding posts.

  7. I'm so glad you asked! The Z-mod is a prototype modification for the M500t mkII and M1.0t mkII amplifiers. The modification will be switchable. It is intended to make the amplifiers more responsive to high sensitivity speakers, such as horn drivers and ribbons.
  8. The IEC socket is modification Nelion Audio is happy to offer. I have plans to build better production resources so that we can offer socket install at a better price point. Thank for the info!
