Just replace my tubes.

I replaced my 12AX7 electro Harmonix with Northern Electric.  So, far so good.  I was getting some weird high end freqency but then went away.  I think I just need to break them in???  But after that faded away my amp sounds amazing!!  I will be changing out the EL34 Electro Harmonix for Tung-Sol EL34B.  I just have to take it to a guitar shop and have them bias it.

 

So, far just changing those two tubes make a great quality in clarity.

    Tungsol El34B seems a nice choice , I was going to buy them but finally made some research and paid more to

    get a pair of Gold Lion KT77 ... it is really the best of both worlds between EL34 and 6L6 , I like the sound better so far than the stock EH EL34 . Pre amp tubes; I got another EH 12AX7 gold pins(phase inverter) and a Gold Lion 12ax7 . the amp sounds louder , cleaner , less noisy.

    OK Northern Electric **Beware**,  they seem nice a clear but the tubestore.com is a little shady.  I bought the Northern Electric and I had a tech look over my amp when he put in my Tung-Sol 34b. Remember that ring, well the Tech said it was microphonics on one of the Northern Electrics.  So I called the tubestore.com and I got a guy on the phone.  He sent me a replacement tube and I mailed him the microphonic tube.  Well I put in the tube and guess what, tube RATTLE!!!...  I just hit one or two notes and it rattles like crazy.  It's driving me mad.  I am going to replace them outright, I don't want to deal with the tubestore any longer.  I will try something else with more research.  I would like something with clearity with maybe being EQ flat for a guitar amp is this hard to find.  I'm willing to pay good money for them.
