who do they source them from? any good? what do you know?
Yeah Mesa's a good, durable tube, at least the 6L6s are. I usually have those as backup and they perform just fine and the matching is pretty good too.
When you see coded pairs like green, or grey, or red they're just coded that way when using as a quad. Reds with red, greys with grey. At least I'm pretty sure that's how it goes.
I've never had a problem with Mesa tubes. A lot of people see Mesa as gouging them on price for relabeled tubes. But once you factor in shipping, the same tubes cost the same from any of the reputable dealers. I have no problem with Mesa tubes. I'm not really into tube rolling anymore though so I don't really care about power tubes.
You can use any preamp tubes in any amp, so I def don't buy Mesa preamp tubes. My RA-100 has a Mullard Preamp in V1 for the gain channel and a good phase inverter.
You mean PAIRS.......inner pair and outer pair of tubes should be matching colors.
No man....it is pairs....100%.....and i am talking colour not tube type.Pretty sure the whole quad is supposed to match, unless it's a Mark IV or prior Mark running Simuclass, in which case you can run 6L6s in one pair and EL34s in the other if you want (I think the EL34s in the outer sockets?).
you take out all the mesa tubes, put them away. buy whatever your choice of tube is, run your mesa with those. when you need warranty service, plop the original mesa tubes back in the amp. warranty problem solved.I have had pretty dismal results with the Mesa Tubes.....many go microphonic or just **** the bed rapidly.....only reason I run em is warranty demands it.
NOW: I think the reason why is simple: I live one hell of a far distance from California....so the shops around me have tubes that have been shipped right across the continent and I think they have had the piss shaken outta them by the time I get them!
SO: If you are near california....you may have better luck.
I cannot recall how many have gone bad in the year and a half I have owned my 3 Mesa's.....I would guess I have had at least 10 MESA power tubes (6L6 and EL34) **** the bed on me.
4 of these I blame on Mesa directly......they shipped my Mark V Chassis back to me with my new 6L6 tubes wrapped lightly in the thin bubble-wrap...BUT they were loose in the shipping box...so they bounced and banged for the week it took UPS to ground ship it from Petaluma to Ontario Canada!!!! Needless to say....they promptly redplated and were microphonic to begin with.
That could bite you in the arse.....especially if the other brand tube fries something in the amp.......from red plating for example.....then you throw a good mesa tube in and send it off...they could disallow your warranty.....just a thought.you take out all the mesa tubes, put them away. buy whatever your choice of tube is, run your mesa with those. when you need warranty service, plop the original mesa tubes back in the amp. warranty problem solved.
i changed the tube after it stopped working and before sending it in of course, wanted to make sure that wasn't it. oops, i must have thrown away the bad tube.That could bite you in the arse.....especially if the other brand tube fries something in the amp.......from red plating for example.....then you throw a good mesa tube in and send it off...they could disallow your warranty.....just a thought.
