This really goes more to newer amps. If so which brand, why and what did you think compared to the stock tubes.
I have them in 4 of my amps right now; Suhr Badger, Clark Kanee Reverb, Clark Beaufort, BF Bassman. They make every amp I put them in sound better. Keep in mind my only other experience with NOS 12AX7's would be with Mullards, which are nice too, but usually more pricey. I'm far from an expert.What amp do you have the Brimar in?
Well, a good NOS 12AX7 should last a hell of a lot longer than a NOS EL84, so factor that into the bang for the buck equation.I have been looking at that tube for weeks from KCA. I have used JJ EL4's and now have a pair of TAD's I am trying, but wonder if a pair of GE or Philips would help. It is essentially the same price for a good NOS pre amp tube or a pair of NOS EL84's.
I put some old stock 6BQ5's in my Crate palomino V32. I had to clip one of the pins as 1+2 were tied together unlike newer EL84's.Nobody was able to ID them here but they really added some nice fatness to the cranked sound. Bob
Would it be immediately apparent if they weren't compatible? What would happen?I forgot to add that it may be important when using old EL84/6BQ5's to be aware that they may not be compatible with certain newer amps. Cant remember more than the newer EL84's dont tie pins 1 and 2 together. Bob
No sound or possibly a pretty loud hum. It's also possible to fry whatever component the amp manufacturer (INCORRECTLY) connected to pin 1 as a convenience if you leave the amp on long enough.Would it be immediately apparent if they weren't compatible? What would happen?
