Description

Product Details Vacuum Tube, EL844, JJ Electronics, Apex Matched Pair, Power, Package of 2.0000 T-EL844-JJ-MP Package of 2.0000 The JJ Electronic EL844 is a variation on the classic tube which reduces the overall headroom by 25%. With the reduced power, hitting that rich distortion that the EL84 is notorious for is more manageable. This tube will hit full saturated power tube sounds without having to crank the amps volume as high which makes them a great choice for recording as well as home / bedroom use. These tubes are matched using Apex Matching. Not what you're looking for? Check out our other products in this category: Vacuum Tubes -> Power Click here to visit our ebay store's homepage.
