    Finally! Just Scored an M1.0t - Happy Day

    Great question. I don't think so. The Ohms will stay downstairs with the big Hafler mainly for marital reasons. Ohm offers a really sweet deal to owners of the Ohm Fs. I can get a hefty discount on a new set of speakers if I return them, or I can send back the drivers (regardless of condition) and they will sell me a pair of modern Walsh replacement drivers with new grilles. The new drivers will bolt on right onto the cabinets. Because of the massive size of the old F cabinets the response is boosted relative to the factory set-up for the modern speaker (F2000). The price for this latter option is $1500 US. It is really tempting. I wonder if anyone here has heard the new Ohms?

    Finally! Just Scored an M1.0t - Happy Day

    Update! I tried out the amp last night! Brought the C-1 and a tuner upstairs and this will be the new living room system. Heard a Carver amp for the first time last night. OMG this thing sounds so sweet I could listen to it all day! Even my wife commented on the sound. She described as 'clear' - I have to agree with her. For now I am driving my Cambridge Ensemble (two minimus style satellites with two passive subs in parallel, 6 ohms). Here is a picture of the current rig. The Luxman tuner must return to the basement (it just doesn't match), and the Kenwood receiver will be relegated into storage. I sold my house and will be moving into a new one in a couple months. The new rig will see the Cambridge replaced with 901s on tulip stands. Thanks to you all for the excellent advice! David

    WTB: Carver Tuner

    Thanks for that! I tried the new (for me) amp last night. OMG does it sound fantastic. Even my wife noticed the difference in sound, and both my wife and sonncommented how the matching amp and pre look awesome and that therefore a matching tuner is required. I knew about the TX2 being shorter but did not know the TX11a being available in anthracite. Now I am looking for one of those LOL. PM sent.

    WTB: Carver Tuner

    Hello: I am looking for a Carver tuner to round out my living room system which will be my new M-1.0t, My old C-1, and my Sony Jukebox. Need a tuner in the living room for sure. Visually I think the TX-2 and a TX-8 could both work. Kinda partial to the TX-2... Anyone looking to unload a tuner? Thanks! D

    Okay - thanks for the advice... I will open it up and look at the large caps to check for any signs of distress. If I see bulging or convex tops, then I will be at least doing a cap upgrade first. Best regards,, D

    Is there a list of techs who can do the MkII upgrade? I saw it once but I have not been able to find it since...
  7. Hi Everyone! Just wanted to let everyone know my quest is over (for now :))...! Finally got myself the amp I wanted - an M1.0t. This one is the inverting model, and the owner says to his knowledge it has never been opened. No issues apparently... He was using it bridged to drive the sub in the picture (it has a blown plate amp). I asked the seller to throw the sub in and he graciously agreed. I have not seen this baby in person, I should receive it soon. My brother did the transaction for me and tells me the face plate looks really good (not perfect, but very clean)!

    That is a 1090. Quite fond of that unit. The controls need a good cleaning and it undoubtedly could use new electrolytics, but it sounds great and cosmetically it is very good. I paid about $200 for it, but that was 7 years ago. If I were to do this again, I would hunt for a pair of series IIs. After refoaming all 18 drivers (it took months of an evening here, an evening there type work), I have to wonder how long it will be before the foams are toast again (I can hope that modern foam lasts longer). But with the series I and series II, the surrounds are fabric and in theory never need to be replaced. I have A/B'd the series IIs against the series III and I cannot tell any appreciable difference. If anything, it seemed the series II sounded slightly better.

    All that gear is totally stock. The Halfer pre-amp (not shown) has been re-capped. I am quite proud of the job I did on the RCA connectors, shown here... Next I am going to replace a few of the key resistors with metal film, and replace the coupling caps. Currently using Niobiums (a modern replacement for Tantalum) for the output couplers, with Nichicon gold electrolytics for the input phono couplers. these did not degrade the sound at all, they just did not improve anything. I think that by getting some suitable films in those positions I should be able to create an audible improvement... One of the challenge amps I think would be a cool piece to have. I suppose its not a need... Here are a couple of pics of the 901 restoration I did. That was a fun job. These are in service in my Dad's living room for the forseeable future, but I would love to have a pair in my house. It seems they are not popular in among audio folks, but I love the sound.

    What are you listening to?

    Story goes that SRV laid this track down in just a few takes on a borrowed guitar. What a fabulous recording this is.

    I was looking for someone in Vancouver who reportedly was good at rebuilding these. When I contacted the boutique where he used to work he unfortunately had passed. The gent I was speaking to was very helpful and actually suggested I install a set of tweeters. The thought of crossovers put me off. Your active EQ idea is cool.

    Yes! Thanks for asking. There is a foam liner inside the upper portion of the cone that Ohm says they could never repair. Oddly, those still appear intact on mine. The suspension has been replaced on both drivers. To me the bass is terrific, but I feel they lack in the treble dept. They are very powerful in the bass dept without any mushiness whatsoever - just outstanding bass. They are very power hungry 4 ohm speakers.

    I should have known you guys would ask for pictures! Here are the before and after shots of my brother's SR-903. It was grimed up with nicotine and coffee stains and all bulbs were burnt. I converted everything to LED, but then I slipped with my probe when setting the idle current and severely fried the left channel. Ended up replacing all the output trannies, several drivers, and some diodes - and of course did the same repairs on both channels. The troubleshooting was tricky and took a long time - but it works great now. My bro has an amazing vinyl collection and he is now blasting music in his new man cave with his cherished receiver. I'll dig out some other project pics and post them this evening. Happy Friday everyone! David
  14. Hello Everyone! Just wanted to say hi from frigid Canada, introduce myself, and comment on what an intensely cool website this is! I joined this site a couple months ago, so this is long overdue. I am not really an audiophile, but I truly enjoy good sound. Growing up in the seventies my Dad had music all over the house, pretty neat gear, and there were always stereo/hifi magazines to flip through. I remember marveling back then at the Carver cube ads. I thought they were so cool. Somewhere about the mid seventies my Dad's best friend's wife evicted a pair of Ohm F's I guess because they took up too much space. They ended up in my Dad's possession and a short time later he had a Phase Linear 400 amp and the matching preamp. My Dad encouraged me to blast the music as long as I was careful. Fast forward thirty years or so and my Dad's 2nd wife evicted the Ohms again. This time they ended up in my basement! That was almost ten years ago and the first thing I did was to acquire the first serious power amp I could find locally - a Hafler 500, with the DH-101 preamp. I also scored a Marantz 1090, a Luxman CD player and I also found a pair of JBL Decade 16's that my neighbor put out in his trash. One of the woofers fell out!!! That took me all of about 5 minutes to fix, and what a great sounding pair of speakers they are. In recent years I have been trying my hand at fixing up old gear. Started by recapping and replacing all the jacks on the Hafler preamp (honestly, I could never hear any improvement). After that I came across a basket case pair of 901s with a dead EQ that I restored from the ground up. That was a very satisfying project. Then I restored my brother's Hitachi Receiver (a 150W class G beast). Just this last December I realized I never was satisfied with the preamp work on the Hafler, and I got myself a stock C-1 control center. OMG what a difference!!! So that unit is currently controlling everything with the Hafler 500 driving the Ohms. In the other end of my long basement, the Marantz drives the JBLs. My vinyl sound fantastic through this rig. I am currently on a mission to get my hands on a Carver amp. I am totally lusting after one of the transfer function amps. Top of list is the M-1.0 T. I also would love to have a 1.5 T or an M-400T. Any of these I would take dead or alive (preferably dead but cosmetically good). I go after every one I see, and get out-gunned every single time. These beauties are certainly sought after! The extent to which they have held their value can only serve as testament to the genius and ingenuity of Mr. Carver! Not sure if i will ever succeed in my quest, but I am sure enjoying the journey! I am grateful to have found this awesome site, and look forward getting acquainted with you all! Sincerely, David (aka Cool Ohm) Ottawa, Canada
