[1 pair EL34-PH]

About Matching:
All of our tubes are matched in factory workshops.
Match is accurate (not all tubes are matched).
It has the requirements and benefits of multiple tubes (4, 8, and 10) to meet your needs. Parameters are the same)
Purchase 2, Buy 4, Buy 8 = Exact Match (matching pair). No parameter drift
Note: (Dont think it is a fake or overlooked product after you receive the tube) If you buy only 1 pc. No original package.
