Set of 4 NEC 12RHH14 9-pin miniature composite tubes. These are rare vacuum tubes used in older televisions for video output, etc., but some people also use them for DIY amplifier construction. This time, we are selling them as a set of 4 due to inventory clearance. ✅ Report of Simple Inspection (Tester Check) Results We do not own a dedicated vacuum tube tester, but before listing, we performed a basic continuity check (tester check) on all tubes and confirmed that there were no defects in the following items. [Confirmed by Simple Inspection] No filament (heater) breakage: Resistance (continuity) was confirmed between the heater electrodes (pins 4, 5, 9). No short circuit between electrodes: No short circuit (continuity due to contact) was confirmed between the heater electrodes (pins 4, 5, 9) and all other electrodes involved in amplification (plate, grid, cathode, etc.). ☆ Notes on purchasing (Please read carefully) This product has not been tested for "emission capability (actual value)" or "amplification factor (Gm)" using a dedicated vacuum tube tester. The tester check is only a simple inspection and does not completely guarantee operation in actual equipment. Please bid only if you understand that this is a "as-is" sale, as these are vintage parts that have aged since their manufacture. ☆ Product Details Model number: 12RHH14 Brand: NEC Quantity: 4 Condition: Unused dead stock, or near-new condition (※ Please check the condition of the original box in the images)
