Electro-Harmonix Factory Platinum Matched QUAD (FOUR) 6CA7 6CA7EH Power Tubes
Matched QUAD Electro-Harmonix EL34
New, factory platinum matched set of FOUR Electro Harmonix 6CA7 tubes.
These are burned in for 24 hours, factory matched at real world voltages and then the test results are labelled on each tube box.
This new production EH tube is manufactured at their Xpo-Pul factory (also known as Reflektor) in Saratov, Russia.
The Electro-Harmonix 6CA7EH tube is extremely musical, with a sound that is rich, smooth, and highly detailed without being edgy. It is the perfect 6CA7 for vintage equipment and a sure way to improve the performance of modern equipment.
The factory matches these at 400V plate, 250V screen and -17.52 bias. Insist on factory platinum matched tubes for best performance.
