Hi. I wanted to grab a pair of 6SL7 river tubes for my Cary SLA70A Signature amp. I'm currently using a used/tests strong pair of Sylvania VT 229's from the 40's. These tubes are outstanding but slightly forward although I'm willing to buy another pair they are that good. So my narrowed down choices are as folows:
Tesla ECC35 from the 70's- $120 a matched pair.
Tung Sol 6SU7GTY- $95 a matched pair.
Sylvania VT 229- $65 a matched pair.
If you have any experience with these tubes as a driver in a power amp, please let me know your thought. Thanks.
