  1. I bumped into your site this evening after having an M1.0t throw a curveball at my 60 years of experience with power switches. (The contacts open to turn the amp on!) I know, you already know I had my own shop for 8 years in New Haven, '72-'80, Factory service for Sherwood, HK, Nikko, Onkyo, Fender, Gibson, Moog, Infinity, Hitachi basically anything sold in Southern Ct. Then tech at Tech Hi-Fi, Service Manager-Head Tech at Absolute Audio (4 stores), Sounds Alive (7 stores) fixed VCRs for a couple years then 20 years of PCs, Phew! Retired now, part time back to fixing the same stuff I was factory service for in the '70s and '80s at the local record store. I even took in 2 pieces with my old store's stickers on them, I gave 'em a 3 month warranty on the work, I guess 40+ years means I did OK. I remember being Carver service at Tech Hi-Fi but they weren't selling Cubes, no magnetics, or if they did, nobody broke one. If I can't figure this M1.0t out in a day or 2 I'll be back, well heck, I'll be back either way. Thanks for letting me in Kevin G

  2. Hi there, new member. Own a C9 and TX11 bought in 1980 and not used for a while. Experimenting with recording audio and would like to use the C9 in playback system. However, my C9 had a problem in left channel very early on and I am looking for a schematic so I can try to fix it (and upgrade parts). Also interested in more technical detail. I think we should be able to replicate the holographic effect using a DSP. Could be done in real-time or perhaps by preprocessing recordings (looking at Mid-Side recording…). Hoping to find the info here, or get pointers as to where to look further :-)

  3. Hello everyone I wanted to update you all that I just posted List 1 of Barry Galvin's Estate sale on the Novice's gear (FS/WTB) forum. Apologies for the long delay I injured my ankle and wasn't able to go to the storage unit and get an inventory and was only able to get a partial inventory but wanted to get things moving. I believe there are about 10 more pieces of equipment and more components to post. Thank you all for your patience.

  4. Welcome! You can get schematics and service data at the top of any page by clicking on the 'Manuals and Specsheets' tab. As to recording, I've done a fair amount of location recording over the years (almost all acoustical) and the closest I've come to reproducing the Sonic Holography effect has been with the Neumann KU 100 Dummy Head. If you aren't familiar with the KU 100, it essentially produces a binaural recording taking into account the natural spacing of our ears and the accompanying time delay. And while the effect is good with quality speakers, it's great with headphones where room reflection artifacts aren't present. I think the KU 100 is somewhere around $10,000 right now, so kind of tough to justify to simply play around with it The genius of what Bob Carver figured out with SH was how to deal with the left/right delay and room artifacts in a normal room with normal speakers. The only real requirement is to make sure the listening position is at a nodal point so the cancellation effect is at maximum. I know many have recorded Sonic Holography encoded content and got good results. I'm not sure how one might use DSP to do similar, but I suppose a contemporary engineer who's familiar with that tech may have some ideas. And there are some good threads here on restoring/upgrading the C9 and some members with some real expertise with that unit. Try a search and you should find plenty of info.

  9. I'd like to take this opportunity to say thank you to all who welcomed me to the forum. On a side note, regarding the reason I stumbled into the doorway....... The M1.0t I was looking to repair is waiting to hear back from the customer, to see if he wants to pursue the repair. I found one shorted output, a 2SB1163, and the triac which refuses to pass current and reads 90ohms from the gate to T1....T2 is open to both pins T1 and the gate. I set up a quick test jig and it wouldn't light my lamp. I saw one on eBay for $40. We'll see what the customer wants to do Then there is the issue of do I replace one output or the entire stack....I can get 2 used Matsushita for about $10 I'll take pics and let you all know how it came out, I assume the customer will OK the repair Thanks again Kevin G.

  14. I dig my old work printer out today to use in my basement. I connected it to my laptop to set it up. The only usb/printer cable I had handy was this one from AudioQuest. Now it will only print images of Diana Krall, Dire Straits or Steely Dan.

  15. What a great video! EveAnna reveals her deep understanding of her craft. Just like Bob does. I hope additional esteemed designers follow suit with similar videos. Videos like this serve well to explain the difference between listening and measuring. The internet has a few who measure. Too bad they are so loud in their voice. The real world has, I dare say, millions who actually listen. Schaumburg will be hosting many in a few weeks.

  16. Welcome @ans1.1, glad you found us. Check out the many threads on the C-9. Hope to see some pictures of your projects in new threads... 😉

  20. Her observations with output transformers and measurements vs sound, is similar to Bob's teachings. This relates to the 275 design running the smaller output transformers at higher voltage potential. They don't measure as well into a test bench resistor, but they sure make beautiful music with speakers. The anomaly she speaks of in bench testing with the smaller, worse testing, better sounding transformer, does not show up in loudspeaker testing per application. Bob views the output transformers as the interface between the tubes and speakers, when determining what sounds best as the 1st priority of the design. These are topics related to how the lightweight 19lb 275 sounds so good in spite of criticism from some who are not amplifier designers. Great designers always prioritize audio sonic performance above all else. Designing to measure well is relatively easy. Going down rabbit holes chasing analyzer numbers and assembling a ranking of audio performance based on SINAD, as if offering a better audio experience or sonic value for the customer, is either ignorance or deception by one measurement reviewer that comes to mind. "Arrogance is a sign of ignorance", so there you go.. "Designing an amplifier to sound the best and designing to measure the best, are not necessarily the same goal." Bob Carver. Thank you to EveAnna Manely for sharing the experience and maintaining focus on what sounds best, as the 1st priority for her company.

  22. hello All ! Olskool here …bought a Carver C-19 preamp today …Being shipped ..fingers crossed it gets here undamaged ,,,unlike my last two items Ive had shipped . Been doing this for years and had very little problems until last week . The Carver TFM55x had one handle smashed sideways and right channel scratchy and hums barely plays … waiting on FedX for ins adjustment ..hope it isnt too badly damaged .! Both items were not packed so well … When I ship something out it is packed as good as i can get it and its not going to be moving around inside the box ,,that is for sure . Crunched up paper is NOT packing material . imo

  23. After servicing quite a few Sunfires, I've noticed their shortcomings as well as areas which can be improved. I am currently working on a relatively universal upgrade for Sunfire AMPs. The upgrade will include updates to the amplifier circuits and tracking down converter for more power, better durability and much better soundstage.
