    After a few months Otari back to life

    With being gone for work for a week or two each month there has not been a lot of time to play with the Otari MX5050 BII

    You may recall I reworked the power supplies and critical regulators as well as did direct out for the heads and had the heads serviced by J. French.

    After all that I had some further pesky intermittent gremlins play havoc with the control logic. First a dual nand gate chip then the edit switch which gates the control voltage for FFW and RW.

    Well I finally had some time to sort it all out . These 30 yr old decks need much TLC. It is sounding great direct out to the deHavilland and Hugh Maskela- wow.

    I don't have much of a tape repertoire but I will order another tape or two this year. It is a bit of a novelty I am enjoying this weekend. It only took about 5 months to get it sorted with my lack of spare time. Those of you that have trusted techs for your decks- cherish them- these are bears to work with overall and I wouldn't do it for anyone but me Click image for larger version Name: IMG_2773.JPG Views: 108 Size: 118.1 KB ID: 61300Click image for larger version Name: IMG_2775.JPG Views: 102 Size: 83.8 KB ID: 61301

    looking good. R2R is so sublime, I am constantly amazed but I have to be judicious about the tapes (cost) we're def playing in the big boy leagues in more ways than one.

    To your point, I found a great tech in So, Cal that specializes in prosumer decks and his assistance has been invaluable, in fact, he was recommended to me by Jeff Jacobs of J-Corder.

    recommended tape techs would make a great resource page for AN if Myles will post one as sticky we can all add our own recos for tape techs in No. America. and beyond.

    Glad you were finally able to enjoy your Otari, I have the same deck all modded and I am also using the Model 222 tape pre. I also have the Bottlehead Tube Repro which I used with my destroyed Studer 810 but, that's another story. I really enjoy my Otrai it has been a gem to this point and trouble free, that's why I think I am gonna just keep it and not get another Studer. I am gonna be listing all the extra's I have for my Studer if anyone here is interested once I find the time to go through it.

      It looks good sitting there with both meters lit.

            You can always spool the tape back to the reel correctly.
