I bought these from another website and they had static/crackling. These don't have these issues. Great buy.

Yeah it is not NOS but I cannot say anything bad. It does draw a lot of current and is really hot

Order number 1xx-xxxxxxx-1xxxxI don't know if I am misunderstanding but to me a "quad" should be 4 tubes.Ngoruh:I apologize for the inconvenience cause. It looks like there is something wrong from our warehouse. I'm forwarding the issue to our warehouse team to get corrected. It might take up a week. Thanks for bringing this to our attention.In the meanwhile, you can return the incomplete item for full refund.Me:Alright.

I had to re-tube my Marshall JCM800 2203KK head and these worked perfectly. I have never played any other tube head so I can't say how well they compare to like 6550's or EL34's but these just rock, very heavy sounding since I play with distortion the whole time, no pedals just the gain from the head. I was recommended to these from my buddy who only gets his tubes from JJ and I will likely be the same way.

These power tubes sound great at a wonderful value! I put them in my Orange Rockerverb 50 MkII and I love the sound. I bought from YenAudio on eBay, and they were matched perfectly. I haven't tried other branded KT88s in my amp but I'm completely happy with these!!

These tubes are better than the branded Marshalls my 2203KK came with to my ear they are unbelievable. All tubes are kinda Prima Donna but hey if you got KT88's and you need 'em you might spend more but I doubt you'll get more!!!!
