I had this bad habit of not reading the user manual when i buy any electronic equipment.
Recently I bought a Cary SLP05 obviously i didnt read the manual just installed everything and started listening to it.
As per the fellow polkers suggestion i started looking in to Tube rolling, that is when i realised the concept of pairing the tubes for a optimum output.
That raised a question why isnt there any indication of that on the tubes that came with my SLP05.
So i checked the packets in which the tubes came in which has numbering on them clearly indicating where each tube has to be placed.


I contacted cary if they can help me re numbering them but they are asking me to ship the entire unit and pay 125$ + shipping for both ways.

Looks like i am better of buying a new set paired tubes than asking their help....


The thought that it would have sounded better if i had the tubes plugged in correct, is really killing me.
Damn me!

Serioulsy though, i almost paid a used car price for this and they are not willing to use the tube tester or what ever schematics, just to put the numbering back ..... anyways it is still my arrogance i should have been little carefull.

Anyways i have to start looking into tube rolling.

    That isn't very nice of them, IMO. All that needs to be done is put them on a tube tester. Maybe a fellow Polkie with a tester would be willing to help you out.

    Yup didnt want to complain about it since it was my mistake but it did leave a bad taste the way they want to handle it.
    Actually there was a screw in the power unit that came off and was making noise when i was installing the pre amp...which i have to fix it by my self they actaully wanted to be ship the unit so that they can fix it.

    Many feel that actually getting a matched pair is an impossible task. You can get them to test close, but how they operate under stress and all that good mess is much harder to predict.

    And also i am thinking to really hear the difference one should have a trained ear?

    It's like I said before, using matched pairs in a line stage pre amp doesn't make much sense to me.

    What makes sense, and I've said it a million times, Read the darn manual....twice. Especially with receivers, and especially since it's your first time owning a particular piece.

    Well, you kicked yourself for that already so I won't harp on you. It is possible to buy a tube tester if you look used for maybe a few hundies. In any event, I wouldn't stress too much about the matched pair thing. You have to be careful and know what your doing as I also stated before, because shipping that puppy with insurance isn't going to be cheap....as you just found out.

    If you can't hear a difference, don't waste your money.

    Not sure why Cary would say to send the whole unit back just for tube matching as it would imply they might think you'd have to send the whole unit in every time you wanted to install a new tube so it's matched and balanced with the circuits in the unit. Doesn't make sense to me, so maybe there was a miscommunication. As it is, the Cary in stock form uses inexpensive Electro Harmonix tubes which are widely available. You could just get in touch with a seller like Tube Depot, Tube Store, or another and explain what you need and they'd probably provide you with good advice on what to use based on their experience as the SLP 05 has been on the market for quite a long time now. They'd be able to set you up for around $200 with new matched and balanced tubes unless you wanted to go with more expensive tubes.

    Since you installed them in a random order I would just develop a plan that allows you to rotate them in a known order, and then choose whichever pattern sounds best. That gives you an inexpensive way to practice tube rolling, and if you hear no difference then you can feel better about its performance.

    Yup... For that price I can get a new set.
    They agreed to do it for 25$ but I am not confident if they will fix and return it in timely manner.
    they haven't replied on how many days would it take for them to get it done.

    Yup I got that loud and clear this time.
    I bought far more sophisticated systems than this pre amp but never had this issue before.

    It seems they will optimize the placement of the tubes particular for a given unit...
    yes they used cheap tubes for a 9 Grand pre amp though it sounds great I still think they should have at least used the gold base version of the same tubes.

    I am totally impressed how the pre amp sounded but this will be my last Cary product.

    I don't like their business model.

    Bingo! Overrated and overpriced. Get a pair that's close within 10-15%, even 20% of each other.

    Why should Cary pay to ship and insure a piece like that both ways for your incompetence? You are lucky you didn't do some damage by using tubes in the wrong places. And HELL YES it will sound better with the correct tubes in the correct spots.

    Good Luck

    For what you are trying to do with a tube tester you will need something better than my Mighty Mite which basically tells you a tube is good or bad. You will need something better for matching that does MUTUAL CONDUCTANCE .
