Fast delivery. Packing of the valves was OK and they arrived undamaged.
These were purchased to replace the EL34s in my Yaqin amplifier. Re-biassing had to be done, otherwise they would run too hot. After setting at 45mV the real fun began. They certainly live up to their reputation for deep and dynamic bass and clear top end. Plenty of definition all round. An upgrade to the el34s supplied with the amplifier then some. JJ KT77 are the king!
I must say they are so good to deal with information is given from the moment you order until receipt. They do also offer very good quality items and at good prices. Packaging is excellent as well. Highly recommend
