Lighter in bass response than my 1960's EL 34 Mallards, well matched, and Balanced, no doubt, (purchased in matched quad) They do what you want them to do, clean clear, no noticed microphonics, a INEXPENSIVE solution, if you don't want to spend double. My amp is more critical than it was before, and yet it did not magnify tube faults, I am still running tube rectifier, I don't care for S/S rectifier.

Great quality and sound! Really like the chimney feel... has punch, clarity, character. Breakup is just where you like it, and singable notes arise just when needed. Shipping was outstandingly fast!

These EL34 tubes with a set of JJ pre amp 12 AX7's gives the perfect Metallica metal sound out of my Marshall JCM 2000 TSL 100. Highly recommend these in your amp if you are looking for that crunchy metal sound.

Tube specs were on the dot and was able to buy a single tube. Had 4 new el34's from a local store and one red plated upon biasing......needed just one and got it within the specs of the others for a matched quad.

Tubes are installed and bias set . So far working fine and great sound. can hear the difference.
