Auction is for one matched pair (2 tubes) of rare 6HM5 EI Yugoslavia made back in 80s for export.
They are special quality, ruggedized version of EC900, also can be used in many 6HA5 applications. They have genuine Philips codes etched on each tube, all of them are the same date.
Great results in Little Dot Amps!!!
I have few 100 pcs service packagings of these tubes, and all pairs I have are carefully tested and matched by plate current on my Metrix U61-B tester. Due to big number of tested tubes, they are matched within 5 - 10%!!! They are tested with 150V on plate and -1.5V on G1.
If you need them closer matched, see my other auctions, I have them available in platinum matched pairs within 2%!!!
