I have an old (about 15 years) tweed deluxe (Wever kit) ,it has a large transformer that can also accept 6L6 . I am currently running 6V6s and a 5Y3 rectifier but yesterday the 5Y3 died and in pinch I swaped it for a GZ34. The amp sounds much cleaner ,tighter and "musical" to my ears and I want to keep it this way. It is also less noisy. Is there any way the GZ34 will cause some damage to the amp,tranny and the ,very expensive,RCA blackplates I am using at the moment?
