Genalex Gold Lion12AU7 / ECC82 (Balanced Triodes)

Purchased this tube as a replacement for the original tube for the sole purchase of allowing a smoother linear increase in volume of my Fender Hot Rod Deluxe (lots of info on the Internet regarding this issue). Using this tube accomplished that however it was very difficult to seat the tube in the socket. The pins on this tube have a larger circumference than the original tube requiring a lot of pressure to get the tube to fully seat. I was concerned that I would break the tube. If not for that problem I would have given this product 5 stars.

sound good on the Bravo Ocean headphone ampEdit: died after 1 year

Thank you for taking the extra time to check and label the tubes for maximum efficiency and quality something you don’t see a lot of anymore when it comes to QC! The brief summary of your business that you included about tonal tubes was a very nicely welcome addition with the order 👍😊 you have gained another satisfied customer! Thank you tonal tubes! My amp rig thanks you as well!!

No difference than the cheaper rung sol
