Last batch was sold out and feedback from the users is real fine on these tubes. Unlike a few years ago, we are finding it very hard to locate these in quantity. Our source was able to find us another small batch at higher cost this time. * You can also find the same tube labeled as ECC803S. This was probably done in the 1980's.
