Ussr tubes 1579 (6SL7)unique military development qty=2
The champion in sounding quality among
the Soviet analogues ( 6SL7 ) Lot of 2 NEW
Does not concede in sounding quality to RCA, GE tubes.
Has close characteristics of parts inside a cylinder,
Microphonic effect is reduced to a minimum, big work resource.
On the top and bottom mica rigid springs are fixed, holding all electrode system inside a cylinder absolutely symmetrically.
If in the description of sounding leave aside the small nuances, that main difference of a tube against 12 7 will be, that oktain has surprisingly clear, much more detailed sounding and at the same time melody does not suffer at all.
