    What would you like to improve upon with the sound, or what kind of sound signature are you looking for? Everyone has different opinions on what is best.

    I don't know. I just want to buy a bunch of different ones and try them out.

    Get an adapter and then try the 2c51/5670 and you’ll be happy, because they’re a lot cheaper then other varients They’re a good tube and for the money, IMO, one of the best. It just really helps what kind of sound signature you’re looking for.

    Check out TK16's profile page, and his list of top tubes. Try to buy as many, from that list you can find, and you will be set.

    If you would like to try a few different types that are really good and relatively inexpensive, I’ll list some options. Question for you what amp are you using?
    Is it a Lyr, or something else?

    recommendations:
    For 396A/6N3P/2C51/5670 etc. variants
    Foton 6N3P or Reflektor 6N3P 50’s era. Both of these are good tubes that can normally be found for reasonable prices. The Reflektor 6N3P 50’s era sound a little better then the Foton, to my ear. For these tubes check with members here first like TK16 and second choice would be eBay.

    If you want to try other variants of tubes such as 12AU7 or 12AT7 variants I would recommend these tubes:

    For 12AU7 variants IMHO probably one of the best ‘bang for your buck’ would be
    Baldwin Raytheon 12AU7 long shiny black plates, these can normally be found for around $25 for a pair, on eBay.

    Further recommendations for 12AU7 variants that you can purchase from the well respected company Tubemonger are as follows:
    1. Brimar ECC82 1970s HALO-DISC Getter Short Plate Mazda LABEL - Thorn-AEI - England https://www.tubemonger.com/MINT_NOS_BRIMAR_ECC82_12AU7_1970s_HALO_DISC_GT_p/1236.htm
    1. Tesla (NOT JJ) 1975-82 Military Long PL. ECC802S prem. https://www.tubemonger.com/Tesla_NOT_JJ_MINT_NOS_1975_82_ECC802S_Tall_PLCZ_p/1012.htm
    For 12AT7 variants, that you can purchase from Tubemonger
    1. Brimar CV4033 Military Black Plate Prem. Grade Long Life ECC81/CV4024/12AT7 Halo Getter STC Prod England 1960-62 https://www.tubemonger.com/Brimar_CV4033_NOS_1960_62_Prem_CV4024_STC_Eng_SLIM_p/2042m-sl.htm
    1. Siemens & Halske E81CC - 1960s 3-MICA 6201 Munich W. German Prem. ECC81 12AT7 https://www.tubemonger.com/Siemens_Halske_1960s_3_MICA_E81CC_Munich_ECC81_p/629m.htm
    All of the above tubes I recommend are tubes that I own and have been very happy with.
    Further recommendations would be for Socket Savers if you do not already have some, as these will protect the sockets in your amp for tube rolling.
    My recommendation would be Tubemonger’s socket savers as most of us here use these, (very well built and have the added benefit of helping to reduce noise on tubes that are microphonic because of their vibration resistant bases). Tubemonger also makes 12A*7 to ECC88/6922 adapters (highly recommended as these are also extremely well built and have the same vibration resistant bases as their socket savers.)

    Tubemonger Socket savers
    https://www.tubemonger.com/NOVIB_Socket_Saver_1960s_NOS_British_McMurdo_B9A_p/novib-mcmurdo.htm

    Tubemonger adapters 12A*7 to ECC88/6922 basses
    https://www.tubemonger.com/12Axx_to...IB_1960s_p/12axx-ecc88-adap-novib-mcmurdo.htm

    Hope this information helps

    Edit: I originally had the Foton as better to my ear then the Reflektor that was supposed to be the opposite. It is now fixed. So the Reflektor is better to my ear then the Foton.

    Wow! That is a lot of really good info. I am sure many will benefit from that.

    That list is a sham, designed to steer people away from my favorite GE tubes. Any variant even ones that won't work in my gear. They are that good.

    After a brief listen the other night just to see if additional age deterioration had elevated the sound even further, I've decided I like Philips ECG's even more than GE's. They are also a great tube for determining if your high frequency hearing is still intact. If they sound great, it isn't. :relaxed:

    I've heard some treble happy tubes that I detested. GE 5670 50's, Tesla E88CC 70's, LM E 2C51 gold pin/steel pin square getter, Bendix 5670.

    Hello everyone..i'm new here. I've had a Lyr 2 in my possession that I haven't gotten a chance to use, and before the NOS tube train passes me by, I wanted to try to experience what I've been missing before it's too late. In the last wk I've made some tube purchases, but had a specific question about a pair that I just bought. I bought a pair of E88CC Valvo Heerlens with production codes 7LH ◢ 5B4 & 7LG ◢ 2B4 . My question was regarding that pair was is it normal for the first 3 production codes to not exactly match (7LH vs 7LG) ? Also..when was this pair produced? The seller stated that they were produced in the 60th yr, I figured that meant 60s but wasn't sure. Any help regarding this would be much appreciated. Thank you

    1st tube is a 1975, second is a 1972. 7L* is the change code on E88CC/6922.
     
  13. SoundCloud85
    I also forgot to specify that the tubes also have a double stage getter as well.

    http://www.tube-classics.de/TC/Tubes/Valvo E88CC/E88CC.htm

    But can the tubes still be balanced/matched even if one tube is 7LH and the other 7LG?

    Tubes are 3 years apart might be fine. Though I wouldn't recommend buying tubes 3 years apart. Let your ears be the judge on that.

    I have questions about vacuum tubes and thinking this is the right place to ask.

    It is somebody here, who have experience when tubes "are going"? What symptoms I can expected before they die? Can that tubes damage the amplifier?
