Item details

• Tube type: 6922 / E88CC (premium, ruggedized member of the 6DJ8 family, drop‑in for most 6DJ8/ECC88 positions where higher ratings are acceptable).
• Brand: RCA (re‑branded Mullard Mitcham manufacture, “GT. BRITAIN” marked, etched R‑code factory/date stamps).
• Features: Gold‑plated pins, halo getter, grey shields and internal structure consistent with early‑60s Mullard E88CC construction, ideal for high‑end hi‑fi and headphone amps that use 6922/E88CC.

Testing and condition

• Tubes test strong with balanced sections on a calibrated tester, suitable for critical audio use; no shorts or leakage observed at test.
• These are vintage tubes, so very minor cosmetic signs of age may be present, with performance and electrical measurements used as the primary grading criteria.

Shipping information

• Ships from Superior, Wisconsin, USA, carefully packed in individual tube cartons and then double‑boxed with ample padding to protect the glass and pins.
• Orders are typically dispatched within 1–2 business days via a tracked service such as USPS Priority Mail or similar; tracking details will be provided once the label is created.
• Combined shipping is available when purchasing multiple tubes or other items—add everything to your cart and the most economical secure option will be used while maintaining safe packing standards.

Return policy

• Buyer is asked to return the tube in the same physical condition, with original packaging where possible, and include test data or a description of the fault so the issue can be verified and resolved quickly.
• Refunds are issued for the item price once the tube is received and inspected; shipping for buyer’s remorse or compatibility issues is typically non‑refundable, so confirm your circuit’s tube requirements before ordering.
