Selling my spare set of original NOS SUPER tubes from BAT. Was keeping them for my preamp, but I ended up selling it and not getting another one. So, I finally decided to sell these. The tubes are NEW. They have never been installed/used. They're very rare. Every tube has an imprinted BAT logo on it and a 9111 number. According to BAT, this means November 1991. They are the original SUPER tubes certified by BAT. Also, BAT charges $300 per tube (if they still have them in stock).
No Paypal on this item. Certified check or money order.
For my asking price, I will ship within Continental US.
This is possibly the last set of 4 tubes on the market certified by BAT.
