    EL34 / KT77 Types?

    Post by TXFlyGuy on Fri Jan 29, 2010 2:26 pm

    Does anyone have experience (or suggestions) on the following tube brands: Gold Lion, JJ/Tesla, TAD, Ruby, Tung-Sol and
    Electro Harmonix? Other than being expensive, are the
    Gold Lion's that much better?

    Electro Harmonix... Bought 10 pairs when they first came out for my 3 SET amps. Have had 1 die & the other originals are running fine. Good on life & sound. I would recommend these as very good current production EL34's.

    I have had both the Electro Harmonix 6CA7 and the Ruby EL-34STR. The Electro Harmonix are great sounding and have increased bass response over standard EL-34's but I have noticed some drift in bias with one of my quad and I really should replace it. The Ruby's are a fatter glass than regular EL-34's and have a more robust appearance in an open amp. Other than that I am not impressed with their sound or construction as some lean over in their bases. I believe they are made by Shunguang, China. I am however impressed with NOS Russian 6P3S-E tubes and at between $20-30 a quad they are a bargain. I paid $27 for a tightly matched quad. They have great mids and highs, but are a little lacking in bass until they burn in. The will produce somewhat less power when subbed for EL-34's, but are well worth the small sum of money.

    The 6PES-3 are great tubes. I had Mullard tubes that came with my ST 70 but have run thousands of hours. The Russian 6p's sound nearly equal to or better than the Mullards.

    Granted these Mullards have seen better days, I'm sure new ones would be better, but barely I'm guessing.
