TAD – 6L6GC-STR
High Performance Audio Beam Power Pentode
The new 6L6GC-STR forwards the low end with pressure and has all the guts and bite to perfectly
accomplish all those sounds from big cleans, classic R´n´R like SRV to modern hard rocking
tones. It´s all there with live and breath and the little magic in tone that inspires to keep playing.
This TAD 6L6GC-STR combines the famous reliability of the American-made Philips/Sylvania STR
series plus the beefed-up blackplate system like the highly regarded vintage RCA 6L6GC tubes.
We joined best of both worlds! Silky top end combined with deep bass response and lots of
headroom make this tube a living classic.
