EL 34 tubes

Looking for EL 34 tubes for a Leben amplifier.  Not ready to spend the dollars needed for NOS.  Any suggestions on currently produced options for EL 34?
Siemens EL34's.  Hard to come by these days without spending big bucks.  
agree w others here who have mentioned new production russian ’reissue’ gold lion kt77 and mullard/tungsol el34’s are the best of the lot

as with most tubes, they need some burn in time to settle into their true sound character
Langrex has some Winged C Svetlana tubes that are sold as quad matched pair and sound good. I ran these in my Air Tight amps with great success. I would also second the Gold Lion KT77. Jeff Day at a positive feedback likes the Sophia EL34s in his Leben but they are pricey.

Word is that the 6L6 might be interesting too, assuming you have a CS600.

i have had poor luck w JJ EL34’s in the past in both sound quality (harsh treble and mids) as well poor reliability ... but others seem to have better experiences more recently
