New old stock 9 pin magnoval beam power amplifier with top cap. Various brands. Both EL509 and EL519 are European designations for the US type 6KG6A. The EL519 has slightly higher screen ratings, but they are normally interchangeable. Note that European-made tubes are taller, with a seated height of about 4.5". US-made tubes have a seated height of between 3.8" and 4.0". The picture shows the height comparison. If buying more than one tube, we choose tubes of the same height, if we can.
