Shuguang Treasure series 6CA7 = EL34 Special Edition vacuum tube. Factory matched pair or quad.

To celebrate 50 years of vacuum tube production Shuguang issued several Premium Quality Special Limited Edition types including the EL34 6CA7. These are now very rare.

Upgrade replacement for EL34/KT66/6L6.

Factory matching is often not very accurate. We double check matching better than 10% using an AVO characteristic tester for current, shorts, leakage etc for quality assurance. Plus all valves are actually audio tested for minimum 4 hours for audio quality, noise and stability that may not show up in other tests.

For pairs or quads, free matching for best performance.

Please note that these valves come "bulk packed" so will be sent in white boxes.

Any questions please ask first.

Please note:

Buyer pays for returns and original shipping charge.

Subject to a 10% charge for re-packing and testing.

Buyers with low or negative feedback may be declined.
