Description
A perfectly matched and balanced pair of ECC82 tubes; labelled Haltron London
Detailed description
This is a pair of new Haltron ECC82 tubes in their original boxes. They are rugged tube with a single Halo getter. I have no idea were and by whom the tubes are made; my guess is that they are from RFT! So how they will sound remains a mystery until you have them in your audio system.
The tubes have excellent test values that match the factory specification very well and balanced systems.
Test method & results
The tubes have been tested carefully with the official Telefunken test set-up and our sophisticated test equipment. Please read our testing method for the ECC82 tube family.
