Ruby tubes vs jj.
Ruby post by jason41224 mon oct 04 2010 11 09 pm i could never get into nos tubes unless i consistently could get a supply of them.
Higher grade hand selected jj 6l6gc from ruby tubes.
Select 3 hole plate kt88 made by shuguang in china.
I am using a paduak and curly maple custom hollowbody w duncan 59 humbuckers i think this paring is kinda bright and.

Jj vs ruby preamp tubes.
Tall bottle solid black plate.
As you use your tube amp tubes wear out due to the heat it generates.
It would be lame to splurge on one and wait a few months and go back to normal tubes.
A comparison of current production 12ax7 tubes.
Jj 6v6 tubes are very reliable but don t sound like 6v6s to me.
A couple of years ago these were great tubes but in early 2019 we started getting way too many that were bad crackling right out of the box.
Also re marketed as.
Nov 5 2005 1 i have a gig tonight i am using ruby el34 s and 12ax7 s the amp is a hughes and kettner duotone.

Today it is by far the most common preamp tube used for electric guitar amplification and there is an almost overwhelming supply of current production options to choose from.

The sovteks rattle and they put out too much voltage.
I ve not tried them this year but since the eh 6v6 is currently working so well and sounding so good we re sticking with them unless things change.
With a nice grind.
Ruby el 34bstr s when you turn the volume up are going to break up much sooner than jj e34l power tubes and will sound warmer.
Start date nov 5 2005.
This is more accelerated on output power tubes like 6l6.
This ruby tube is a re labeled chinese shuguang tube.

Groove tubes 6l6ge amazon us http amzn to 2f0wct4 amazon uk http amzn to 2mywnav do different 6l6 tubes and equivalents such as the 5881 make any s.
All current production 6l6 tubes are great tubes.
Jj s 5y3 rectifiers are good but they can rattle in a combo.
I like ruby 6v6s.
Last choice ruby 6v6gtstr.
