Very Rare Techtube Blackburn Legacy E813CC tubes. Equivalent to ECC83 or 12AX7.
Made in England for a very short period in 2009. This is an unique planar design, unlike other tubes.
They have had some light use in the same amp- no more than 100 hours. They will still be good for near to 10,000 hours.
Sound is incredible, clear like a modern tube but with some lushness too. The very biggest advantage over modern Chinese or Russian tubes is that they are totally grain free and it’s really obvious. They are grain free like some vintage tubes but still clear sounding. The reputation of these tubes is well deserved. Have a read around regarding reviews.
These are very rare and sought after tubes. It would be very unlikely to find these brand of tubes for sale elsewhere Buyer will not be disappointed.
