    Default First Time Tube Roller, Pair of 6SN7's Required.

    Had a recent discussion about my Monoblocks, the outcome is I would like to experience the effect that different 6NS7's will have on the SQ. There is only one of this tube type per channel, so this seems the most economical start point.
    As a result of my initial investigations, I am now aware of other variants to these tubes, and the Loctal Base Tubes as well.
    I had a offer on a batch of single valves, that could have been assessed on one channel performance, the vendor then asked if I were happy to let somebody else take them, which I was OK with.
    As a first experience I will stick a pair of 6NS7's. I can try a single tube of another brand in a channel at a later date.
    If there are any Matched Pair NOS tubes available, I will be happy to look into them for usage.

    I highly recommend you try the TAD 6SN7's John.
    All the old tubes I tried were very coloured in my pre whilst I find the TAD's essentially neutral and better at frequency extremes. I'm using a quartet of these tubes now.

    I have a quad of these and am willing to let go of a pair for half original price if your interested.

    They have less than 50 hours on them and are matched.

    Thank you for the link and reading.
    I have researched the net and this thread did not show up or I overlooked it.
    Well one things for sure, you have 'Worn the 6SL7 T Shirt'.
    I am not up to speed on how the valves types differ in their function.
    Pleasing to me is my first Matched Pair NOS to be purchased, is the Sylvania 6SN7GT.
    I will also have a TAD Matched Pair as well.
    There are a pair of early Raytheons 6SN7's on offer, but I will work first with the above tubes against my EH ones.
    Your detailed evaluations and scaled scoring and photo,s of the tubes, are a great help for future investigations.
    I'm now glad a valve that seems to have a real influence on the SQ, is limited to one per channel. It makes it a more affordable experience .
