The undisputed bargain of a lifetime in a bargain EL 34 integrated: The Cayin TA-30, around $ 700.00 used.
They usually have the extended bias option built-in, meaning you can use a wide variety of tube, including the 6550, KT-88 family of tube.
PLUS, you can use only 2 tubes and go for a whopping 4 watts (instead of the stock 35 watts/channel) of near-SET sound.
Easy to bias (Paul at TAD audio design can help with biasing instructions), it's a beautifull unit, and looks like a million bucks.
They sold tons, yet they are somewhat scare, as audiophiles keep'em.
Search for one and read all that is written on the web, I don't think you can do better at even twice the price.
Good luck !
