    Hey there,
    My V4BH (3 years old) needs a valve.... one of them isnt lighting up.
    The repair guy says, may as well replace em all, cos theyve never been replaced before! He only stocks Groove Tubes.... is this a bad bad idea or will it not make any difference at all to the sound?
    Should I get my own tubes for it?

    Best

    I think Groove Tubes generally get an "OK" recommendation from people, and I've found that power tubes affect the tone much less than preamp tubes, but I think you can do better. A nice matched quartet set of 6L6 JJ tubes from www.tubedepot.com can be had for probably whatever he is charging for the groove tubes; just get them yourself and have him install/bias them! But, yes, its a good idea to change all the tubes out if one is blown, and matching sets also help an amp perform at its peak.

    Thanks very much, that clears up a few things for me!
     
  4. 3 years is not too long to go. Power tubes can go for much longer than that.

    That being said, now that one has blown, replacing with a matched set is the proper thign to do. Whether or not JJ's or GT or Sovteks or numerous others will make a difference is up to you and your ears. Some claim absolutely there is a difference, others, nothing.
     
  5. Winged C finals in my V4BH.

    Preamp and the PI are a mix of NOS.

    I'm thinking about fresh power supply caps on mine due to the age of the amp.

    I purchased my finals from Antique Electronics.
