Triode capable of delivering just 4 watts but which are considered by many to be of absolute quality. This pair has almost identical (and exceptional) emission of 54 and 58 mA
It is very difficult to find them on these conditions.
PRICE FOR PAIR
Unfortunately, I also have a third PX4 that has been destroyed, useful to see the beautiful interior, see photo gallery.
