  1. Hello, I can restore the C-500. They are very similar to a Phase Linear 700 - brute force linear power supply and gobs of output transistors. Restoration includes cleaning inside and out, replacement of consumable parts, upgraded components where appropriate, calibration and testing. 3 year parts and labor warranty. $400 + shipping.
  2. Thanks @RobA! Welcome to the forums!
  3. Hey @Bobby1970! Welcome!
  4. The Matsushita's are obsolete. These two relays are direct crossovers: Panasonic JC2AJ-B-DC24V OMRON G4W-2212P-US-TV5 That's all I've found so far. The relay specs are: 24VDC coil, 7A contact, 2 Form A, PCB mount Mouser and Digikey never seem to provide any crossover information. It's a shame.
  5. FYI - we do have some OEM fan motors now. Please contact us if you need a new motor for the PM-1.5.
  6. The A Series Carver Amplifiers were late in Carver's Production years. Although not Magnetic Field Coil amplifiers, they still inherited many of Bob's amplifier topologies that create an accurate, musical and powerful sound reproduction. Although the extent to which Bob was involved in the A series design is not know, it is unmistakably an extension of his earlier designs. The A-series amps utilize voltage rail switching to produce immense dynamic power without having to add cumbersome heat sinks. The high voltage rails are engaged by Power MOSFETS which modulate to the output signal and turn on only when the music amplitude demands, feeding the output sections that are direct coupled with multiple paralleled transistors for high current output. Featuring bridge-tied mode, gain adjustments for each channel, VU meters and 5 way binding posts, the A series power amplifiers are remarkably suitable for almost any musical set up. Our restoration addresses minor failure points, replaces all consumable parts*, calibrates the signal transfer function, and a full cleaning inside and out. We also offer an IEC socket modification, Gold RCA posts, Gold 5-way speaker binding posts, and meter light LEDs for an additional fee. Before restoration: After Restoration: Added speaker binding posts. Price: $350 + shipping Gold RCA jacks: $20 LED meter lights (color of your choice): $20 Gold 5-way binding posts: $40 IEC socket: $40 Nelion Audio 3 year parts and labor warranty included. *We do not replace the main power supply capacitors unless necessary. At the time of this writing, they are still within the life expectancy. If we must, we will quote. Contact Service
  7. The Carver C-4000 and 4000t are similar but also very different. However, restoring them and upgrading them are similar enough to include together. These preamps require a complete overhaul after nearly 40 years of use. We replace all the electrolytic capacitors with either high temp, long life type, bi-polar or low ESR where appropriate. We tear the unit down completely and recondition all the wipers on the attenuation knobs and buttons. Some units require factory updates and power supply fixes. All of these units also require the phono amps, time delay, auto correlator and sonic holography circuits to be tuned and calibrated. The unit is also cleaned and polished, fully tested and we listen to it to ensure it sounds better than ever. The results of our work are stunning! High quality parts and expert workmanship. Gundry Filter board installed on the Sonic Holography PCB. New LEDs for the faceplate. Restore Price: $400 Gundry Filter for Sonic Holography: $40 LED color change: $40 Remote control Volume: $150 Contact Service
  8. @tim Are you having trouble logging in your account?
  9. Did you get it working Tim?
  10. I will very soon. I'm actually working on it this month!
  11. Well, I can tell you B & O is not always easy to troubleshoot. Those speakers are active and they have a display for volume of I remember. Best way to troubleshoot them is to test each of its subsection components. But I think if you follow up on ensuring the connections are solid and inspecting other failure areas such as capacitors and speaker drivers, you'll be in the clear!
  12. Hi Tom. I'm working on both of those modifications. I've wanted a color solution for LEDs for a long time, it just happens to be a little complex when trying to keep the price down as well as accessibility without making major changes to the outside of the unit.
  13. Restoral of this little gem involves replacing all electrolytic capacitors, reconditioning of the output transistor thermal isolators, replacement of critical resistors and pre-drive transistors, service bulletins and full cleaning inside and out. Full restore price: $350 Binding Post Upgrade: $40 LED color change: $40
  14. I have rebuilt them and it's hit or miss. If the brass bushings are worn, then no amount of rebuilding helps.
  15. I sent the email on July 13th to the email you registered with. But no worries, you know how to contact us!
  16. 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
  17. 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.
  18. Hello, We can restore those amplifiers. I will contact you via email and talk! Thank you!
