Revolutionary relativist
My amp uses 6 ECC82 valves in the preamp stage. I've read various people saying, and had recommendations here on pfm, that replacing the stock Chinese-made valves with alternatives can shape the sound a bit.
I'd like to take the edge off the top end if possible - hi-hats can be a bit too prominent and so on. And it's almost universally observed that vintage Mullards optimal for this. But they're £100+ each nowadays, which is daft. I've tinkered with just substituting a couple at a time (currently sporting 2 Brimar 13D5s), but I'm thinking going the whole hog will be more productive.
So does anyone know if there are alternatives - specifically actually available ones from the likes of Langrex or Watford Valves - which might tame the top without breaking the bank?
I've seen mention, for example, of RCA 5814A black plate triple mica being a direct equivalent and at the warmer end. But don't know if that's true, or how to spot the right version if so (only square getter are currently available, whatever difference that makes).
Or am I on a hiding to nothing?
