Very rare Ce RFT (RWN Neuhaus) triode NOS NIB, strong 100%+. Made in Germany (same code on the box and on the tube base, the box is not the best). Tested on Roetest V10.1 (best tube tester). See last picture for results. I will pack the tubes properly(in a wooden box), and will take great care in doing so. PRICE IS FOR ONE TUBE.
