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!
Bought a set of four of these some time ago. You may see my review above. I have bought another set as these sound so good, have performed very well with no problems, and I am aware that supply of these may become a problem in the future. (the war and all that!) You can't beat the price either. Came well packaged as before and fast delivery. Would not like to be without these at all.
Match quad of JJ KT77 valves for £50 plus delivery is a bargain. Very crisp and detailed sound with controlled extended bass. Used in a hifi application. The original order was cancelled for some reason and I was charged for postage on an item that never left the warehouse but I rang customer services who resubmitted the order and ensured I didn’t pay postage again. Valves arrived 3 days later.
