Mesa Boogie STR415 Green Label (6l6)

[mkuster]

Hey Folks and Mesa Boogie Lovers,

I just got my first iic+ (DRGX) Head in Hardwood, this thing is freakin amazing!

Now I already got my first question. There are Mesa Boogie STR415 Green Label Power Tubes in it. Are these "renamed" Sylvania STR415 Tubes and are they as good as the Sylvania Tubes? Or are they something completely different?

I'm very sorry, if this Topic has already been discussed, I'm a tube newby. On various forums incl. Boogie Board, there are a couple Tubes they recommend.

1. Sylvania STR415
2. SED winged C


Thank you guys for your help,
Mike

PS: I'm working on to load up a Picture of the amp, haven't found the right way to do it...haha

It's just a label difference. Whether it says Sylvania STR 415, Philips ECG STR 415, or Mesa STR 415, they're exactly the same tubes off the exact same production line.

Mesa still has some stock of STR 415s if you really want to pay 250 bucks for a pair of matched tubes. Get the STR 440s, Mike Bendinelli thinks they're just about as good as the 415s and they're a LOT cheaper.

Don't toss your 415s without a good reason. They may have a lot of life left to them.

I've even heard of well used ones that are basically toast sell to tube collectors for enough to be worth the effort to sell them on ebay.

Thank you man for your answer.

I will test the tubes next weekend by my amp doctor to see if they are still good. Fingers crossed.

Luckily I saw that the built in preamp tubes are Tungsram EC83/AX7 tubes 8except the phase invert tube which is a ruby.

Hope everything is fine with all tubes, would be lucky me. Otherwise I have to think about it, if the additional charge for the 415's is worth it. But hey, I paid a hell lot of money for the amp, so the tubes are the smaller part.

Thank you anyway, your answer helps me a lot!
