A New version of the JJ 6V6S tube?
Some folks find they can hear the valves rattling in their 6V6S-loaded amps. Usually with specific notes. I see reports of Fender Re-Issue Princetons and Deluxe Reverbs having rattling 6V6 valves. This rattling sound does not come through the speaker but is actually the mechanical parts inside the tube which you can hear. The tube internals resonate when you play specific frequencies. As it is acoustic rattling, this effect is usually only audible in quieter

I thought I would make a comparison of trusted valve ( tube) suppliers here in the UK on one of the most common valves, the popular JJ ECC83S. I looked at prices on the morning of 17th September, 2023. I went through the exercise of buying one piece. In each case, I picked the cheapest option to get a
Fender Blues Jr Dead on Arrival
A Fender Blues Jr Mk III arrived in the workshop. It was dead. The amp was opened up. One EL84 output valve was completely destroyed. The other had most of the getter gone in the valve , suggesting long hours of use. The white material inside the valve indicated a slow gas leak that eventually killed the valve.
