Closely matched and very strong pair of EL35 tubes. The tubes were professionally tested with the following numbers. Tube 1 - White box Ip = 79.4 ma, Gm = 5.8, Gas = 1.2 ma - Code 1028/?M7
Tube 1 - Mullard box Ip = 78 ma, Gm = 5.6, Gas = 0.7 ma - Code 1028/3K7
Really sweet midrange that would work well in a bi amp configuration,,,,These tubes are similar to 6L6G tubes of the time and can be substituted for any 6L6G tube and are the precursor to the EL37 tube.
One tube has a code that is fully intact and easy to read but the other code is partially hidden behind the Mullard logo. The pins are still shiny and not pitted or scratched which indicates little or no use. The rating is because much of the printing has been rubbed off. The tubes are good strong tubes and are a well matched pair I have years of experience buying and selling tubes and have recently rejoined Audiogon. I use the same username on eBay.
