Leben CS600 owners, what tubes have you rolled?

@Kujocku - 6L6GC/6P3S-E/EL34s

All - drop the kt120s in. You won't be disappointed. Better everything but your cover comes off.

Popin the top never sounded soooo goood

Thanks to all for responding, Notec, the 6L6GCs you mentioned were they RCA Blackplates from the 60s? Also Arj your tubes sound like they are burning in nicely, keep us updated if there are further changes.

i still not understand from the response what tubes he mean
The reflector or black plate 60 can u write it clear the name of the tubes
and what about Kt120 what company and its match to leben cs600 or my cover burn
Sorry bout my english not my first lanaguge

kujocku, the 6L6GC's were 6L6GC (5881) SOVTEK, the stock tubes that came with the Leben CS600. Not the blackplates from the 60s.

bolero32, the KT120 are Tung Sol's and yeah, the cover must be removed to accommodate their height.

ok i get this recommend from Jim McShane
(1 quad) 6L6GC-STR Tung-Sol reissue, $87.50
(4) 6CS7 - 2 Sylvania & 2 Raytheon/Japan, $38.00/set
(1) 6CJ3 GE NOS USA made, $7.50

what you think about this set for my leben ,its better then the original tubes that leben put ??
and the kt 120 its better then what Jim recommended ???
thanks alot wait for response.
