For sale is an open box matched quad of Mullard EL34 vacuum tubes (made in Russia). These tubes have about 30 minutes burn-in time on them from my guitar amp, but otherwise are in like-new condition. The tubes test as new on a Hickok 533A for transconductance (Gm) and also on a Sencore TC162 for shorts, emission and grid leakage. No returns.
These are the real deal & in many peoples opinion, are only surpassed by older tubes that are double the price !
