Well my treasured RCA 211s finally bit the dust and now join the GE 211s as display tubes. Bummer so I thought.
Along came Sophia Electric who is famous for their 300B tubes. They now offer a 211s at $425/pr. The NOS RCA and GEs fetch over $750 and $600 respectively. Plus availability is very limited. No tubes no music, I have the supplied Chinese 211s but IMO they suck, bright and shouty, hate em. So no choice.
Right out of the box I was in love. Smooth, quiet as heck, rich, Just wonderfull. Now with some hours on them, all I can say is if you use 211s, 300BS, 6SN7s, 12AX7s or 12AU7s give this company a try. Awesome sound reasonable pricing.
These tubes have transformed my Cyber 211 amps. With the installation of V-caps [ only two required] and these tubes, I'm in heaven. Check them out.
