  4. Hey @Bobby1970! Welcome!
  5. Hi All! Greetings from the Philippines. Thanks Greg and Jenny!
  6. 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.
  7. FYI - we do have some OEM fan motors now. Please contact us if you need a new motor for the PM-1.5.
  8. Greg ... I think those pics are from my A 500x. I must say, you did an awesome job in the repair/upgrade/renewal of this venerable piece of audio history. I am listening as I type these words, and happiness cannot fully describe the experience. Transcendence, rising from the Phoenix, back from the dead ... any of these are close to what this old amp experienced at Greg's expert hand. I thought about putting it on the trash heap, but Bob Carver is an audio god, and even if this is not one of his "pure" creations, it is part of the legacy so I wanted to do my part to keep it alive. So happy I did, and so pleased with the amazing result. Greg, you are a throwback to another time when quality, integrity, and doing what you say was the norm. I salute and thank you for a job very well done.
  9. Just sent in my Carver m1.0t for repair and some upgrades.Heard nothing but great things about nelionaudio!Hope they can bring her back to life!!!
  10. 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: $300 + 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. At the time of this writing, they are still within the life expectancy. Contact Service
  11. Hi Nelion Audio, I recently became nostalgic for my Carver amps and was quite happy to see that there are other people that care about them. This restoration and upgrade is impressive. Vinny
  12. I have always wanted one of these little technical marvels, and the opportunity arose when I bought one to power my C-4000's time delay speakers. Greg did a marvelous job getting my M-400 working flawlessly, and his communication with me about the process was just as good as his engineering skills. Thanks Greg.
  13. Years ago, when they first were sold, I had a C-4000 but had to sell it. Recently, I wanted to return to the pre-amp but I was hesitant because of its complexity and age. Luckily, I found Nelion through the Carversite, and reading the recommendation from Bob Carver about Greg's work was all I needed to see. I bought the nicest one I could find and shipped it to Greg. I received it last week, and it sounds fantastic. I can't take my eyes off it, and can't stop listening to it. Although it is a complex piece, if you truly admire Bob Carver's work it's a privilege to have one of these as the heart of your system, and it's great to have Greg and his team to bring it back to spec and beyond.
  14. 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
  15. Greg has restored 2 of my 4.0 amps and the are perfect and no turn off thump, still have 2 more to do plus 2 PM 1200's !!!
  16. Hi, Compliments of 2020! How's the progress with the above? Best Shoks
  17. Hi Nelion Audio, My recently modified/ upgraded Carver M1.0t has arrived and I've listened, and I am very pleased with its performance. Thank you for packing it so well. It's a long trip from Alaska to Michigan and back. The IEC power socket is a big plus. I'm glad I chose that option, along with the Mark II and the opt002. I'm still listening to the amp and it reveals itself as a magnificent piece of gear. I'm hoping to get many many more years of use from the amp. I give you a 5 star rating because your expertise has taken this amp to a new level. Thank You very very much. Sincerely, Art

    pm 1.5 fan motor

    I would of I would have said something if i could have got back in the site!
  20. Did you get it working Tim?
  21. I will very soon. I'm actually working on it this month!
  22. 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!
  23. 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.
  24. Welcome to all you new members!
  25. Carver service bulletin C1-2 provides a resistor chart for reducing the gain of the Main 1 output. Would love to have a multi-position switch that would allow me to choose different gains. Mine is currently set for the 21dB reduction, but no longer need that much. The normal output of Main 2 is too high for the small space I am in. Secondly, how about leds that you could adjust the color from an external source? My son used to install car kits that allowed drivers to adjust headlight leds using a phone app. Not sure if the technology is small enough to be used in audio applications. Just wondering?
  26. Last month I purchased a pair of B&O Pentas', and as the speakers made in the early 90's, they had some exterior damage and I talked the seller down to a decent price of $600 (these were $5000 dollars when they were new). I plugged the units in and all "seemed" to work well. I was aware that the screen on the unit would not turn on if it was not attached to a B&O music player and figured I was in the clear. However upon getting them to the house, acquiring the proper cables and digital to analog converters for the unit, I set them up and... the speakers failed to turn on. I have since opened the speakers and found only a couple of lose ends that needed to be reattached in the base of the unit, however i'm positive that does not account for the many things that can go wrong with them. The fuses are being replaced as well. Both units have 150 watt amps and have circuitry that run all the way to the top of the five foot tall, 9 driver speakers. Anybody know what I can/should do in this position? Nelion Audio came out to the NY Audio show and thats how I knew to contact you guys so thanks!
