Post by bmenary » Fri Feb 04, 2011 4:23 pm

Hi all- I have a what looks to be older Mesa STR-415 - It has Green print and I also have one with Blue print. I am trying to date the mfg time period for these tubes-

Is anyone knowledgable on these tubes-

On the Green one the codes are

14
28
Made In USA

Again curious about when these tubes were Mfg.-

Hey nice tubes! maybe mesa can help you figure the date codes... but most likely from the early 80's on the green labels. maybe late 80's early 90's on the blue. Where are you in Chicago? Are you looking to sell any? I have 3 blue label that would like a 4th :D . there is a great tech with a shop on fulton next to halsted that will let you test them free. plus he has lots of tubes for sale.

Read from top to bottom 312 is a Sylvania code. Those are some nice power tubes! Bob

Sylvania STR-415's are my favorite 6L6GC! They put the magic in the old Mark series amps. I remember when these went for $15 bucks a pop.

Make sure you get the correct idle current draw when buying non-Mesa branded tubes. Good tube dealers should either provide that info or know which tubes are correct for a given Mesa amp.
