Hi folks , I would appreciate some advice , especially maybe someone has had experience with these tubes I am about to mention.
So I have this old tube amp Priboi, and it uses 6R3S-1 (6P3C-1) in the output and 6J32P in the input, the middle tube as much as I read is actually ok and can be left there in an upgrade.
So the analog for the output 6R3S-1 double beam tetrodes is said to be the russian military GU19 (гу19) and for the input tube the western EF86 made by either telefunken or others.
So tube experts is it worth it in terms of sound improvement will there be actual benefits there ?
thanks.
