I recently purchased some fabulous NOS RCAs -- early 60s vintage from Andy at Vintage Tube Services. I must say that these tubes had an immediate positive impact on the sound. Less noise, more detail, greater dynamics. Overall, I'm very impressed. Much better than I thought.
These RCAs were not cheap though. I'm not sure what your budget is, but the RCAs were cheaper than NOS Teles and Mullards, and possibly NOS Mazdas. Highly recommended.
