  1. 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.
  2. Hi Nahash!

     

    I just sent you a PM on the Carver Site. Please take a look at it when you get a chance. Thank you. 

     

     

  3. to Carver friends   (jan 6, 24)

    I am looking for the best person out there to replace the ribbons on my 1989 Carver ALS  (pair).  Who can you recommend, out of those claiming to be good at this process?  This will be the second time around for me, as years ago James Sauer did the first rebuild, but he is out of business.

     

    thanks for a good recommendation....and even with my tinnitis, I want my ALS sounding perfect again

      Hi Dan, 

       

      The guy to reach out to is @sea (Ed Atkins).  Send him a PM on this site.  Well regarded and many here will be a reference for his work.  Bob Carver recommends him, as he has the jigs required to hold the magnets into place while they are properly tensioned.

  4. We have our own solutions and I can custom order rare parts sometimes. In fact, my custom solutions are often better than a stock part. So my point is about the manufactures and their ignorance/ADHD/neglect of the market. A rather large market! Not about whether we have solutions. Of course we have solutions! It's just in some cases, I'd rather not have to make custom solutions...especially when the parts are out there but distributors just don't keep them in stock, which hints to the manufacturers that they aren't in demand.
  5. Sure, you can order 1000 @ $59.99 a unit, which is about $60,000. Pretty hard to recover that in a fiscal year, unless you're getting a lot of units in for repair that need those parts. Mouser and Digikey sometimes carry these types of parts - but they sell out in just a few weeks, and never bother to restock. It...is...so...strange!
  6. Finding new capacitors to replace old ones is still a real challenge. My favorite excuse on the part of new parts manufacturers is that large can screw terminal capacitors are 'cheaper and better' if they are made with a gigantic diameter and short length. For anyone that's spent any time in vintage amplifiers, these large can capacitors were usually pretty tall (long) with a moderate diameter. First of all - what's the bother of making something already expensive a little 'cheaper'? These large can caps are already demoted to 'on demand' manufacture and I don't think anyone will care if they spend $59.99 a piece or $69.99 a piece to fix something that needs it...and I would bet they'd pay an extra $10, or more, to get the same freaking size they were made in the first place! Then there are the voltages...It's just as easy to find a 22,000uF 25V capacitor as it is to find a 10,000uF 450V capacitor. But exceedingly rare to find a 6,800uF or 10,000uF 125V capacitor. Weird? So much money lost, really, because these new parts cannot fit in old stereo gear anymore. Not even not so old equipment! The ways around the size issue don't involve buying any other kinds of screw terminal capacitors, so the void is nothing more than a complete loss of money and waste of resources on parts that frankly, can't be used. It would make sense to make parts that can be used over a wide range of applications...like...make them the same size they were made for decades before. Millions of applications. But, they don't want that market. Instead, only a small niche market that doesn't need more than 'on demand' manufacturing. OLD vs NEW These don't fit in the same space!!!!!
  7. Hi Nahash do you have a service manual for Sunfire TGA 7201 theatre cinema grand amplifier ?

  8. Hello all! I hope you're enjoying the Carversite! and all it has to offer. The current Administrators are: wrf - Lead Administrator Nahash5150 - Tech Staff AndrewJohn - Community Administrator The current Moderators are: Compwaco - Chief Global Moderator Sk1bum - Moderator An Administrator's job is to protect the community. Admins also assign medals/badges, approve new arrivals, organize the boards, moderate threads, assign roles, maintain the database, enforce the rules, and manage complaints. They also present ideas to the leadership for possible implementation. The Lead Administrator sets the agenda and the rules and manages all the Member Groups. The Community Administrator keeps the information organized, performs regular tasks, and manages the Moderators. Moderators keep the boards safe and fun. Moderators are not here to stifle free-speech, arm-twist or intimidate participants. They ensure that threads are kept organized and remain on-topic, and as active participants themselves, preserve the spirit of the community. Moderators, like the Admins, are here for you so that you feel welcome to share and participate without the worry of being harassed or flamed for it. If you have just signed up, then you are Inbound rank. You have limited access and you can't upload files yet. In order to advance to basic membership, you need over 6 positive reputation points. Reactions, such as 'thank you' to your content increase your positive reputation. There are three basic member Roles: Novice Member Resident A Novice is new to the forum. They have limited access but can participate in the most popular forums such as Way Offscale and The Chain. In order to advance to Member, we expect a certain amount of activity to evaluate their willingness to be a part of the community. The post count required to advance to Member is 100. (If you are currently a Member and don't have 100 posts, you will not be 'demoted'). A Member is considered an active participant. They have nearly full access to the site and its resources, and can progress in rank and earn medals by sharing their experiences in the audio world with the Site. As time goes on, a Member can eventually become a Resident or play a role as part of the Administration. A Resident is a highly active member who calls this place 'home' and acts as a council member with the Administration. Residents are participants who are willing to take on the challenge of discussing site policies and provide the site with valuable resources - such as funds, time and talents. Greatly concerned for the site's well-being, Residents work hard to welcome new 'inbounds', encourage participation by starting topics of interest - and offer Karmas, skills and knowledge to all who visit. There is a special Member Role: Carver repair/mod Team Carver repair/mod Team - Chosen only by the Administrator, these members are trusted with their skill to work on audio gear. They actively take work and offer a variety of services. They are also essential to the site's 'helpful hand' in assisting those who need help with their troubled gear. Carver Repair Team members are also Residents by default. There are two consequential Roles: Retired Sandbox A Retired Member is a participant who has either shown a disinterest in the community but has not violated the rules, or one who has 'moved on' and no longer wishes to be an active member. This is not a disdained Role, but a Role for members who for one reason or another, do not wish to be part of the community's growth (for example). Retirement is a friendly, mutual agreement between the administration and the member. Retired members have limited access. When a participant is Sandboxed, they have violated the forums rules. A warning is always issued before a participant is Sandboxed. If the warning is ignored, and participant continues to break rules or cause trouble - an Administrator, with the consent of the Moderators, will curtail their activity for an indefinite amount of time. Removal of the Sandbox status can only be done by the Site Owner or Administrator. This forum has a lot of options for you to find information, participate, and organize how you read and keep up with activity. Remember that you can do the following: - Follow a Topic (so that if anyone posts to it, you are notified) - Follow a Member (so that you are notified of Status Updates and more) - Post a Status Update (a personal message for your friends that is public access) - Send Private messages - View Activity according to date, member, or topic (check 'Activity' in the top menu) - Post pictures and even create a gallery (Novice or above rank) - Share links, videos and files - Browse technical Manuals, white papers and spec sheets And so much more! Our goal is to maintain a site that is welcoming, helpful, courteous and fun. With audio and Carver as our common ground, we wish to stay focused on the music, and all the creativity that results. Have a great day! Hashy
