Re: New Tubes- Video demo inside
I am not crazy about JJ pres, but I do like the EL84s in my TM18.They are beefier, higher headroom , and a tad darker than the Mullard RIs - all improvements in that amp. In the Class5, the JJs are a little harsh and muddy, the Mullard RI is a bit creamier and open in that amp.
I have bought tubes from Amazon several times, and they were well packed until now. Not sure if they came from a different Amazon distribution facility or what.
I got around to opening up that package tonight for curiosity's sake, and one tube survived intact. Luckily it is closely matched to the replacement set, so I can use it as a backup. The TM is pretty rough on power tubes. It killed a set of JJs and the original ValveCo (chinese) pair.
