You need to stop thinking I have photographic memory of shitty chassis that I fucking hate, and that have sucky worthless proprietary "R" switches I know nothing about.
I can guess.
You wanna play guessing games? Post a pic and I'll take a stab at it after I pull out of your girlfreind and have a look-see.
I AM assuming you're talking about EL34 tubes. You don't specify - you could be mentioning the "R" string tied to the Tonka truck I just shoved up your ass with no lube and in that case - "R" would mean "removal ring". -
Dude, lmfao ... yes the EL34's ... there's an R at the end of the "EL34" ... lmfao ... is that the normal labeling or is it something different that I don't want to use with those 12ax's? ...
Wont have it ti'll 5 ... cause you can damage shit inside right if you mix the wrong tubes? ...Broken down n' dirty dressed in rags ...Comment

great find there Brown ... tried out those new tubes tonight along with the concept of turning up the posat and turning down the gain ... got the levels around 6 post and 4 gain I think ... pretty beefy and lost all the mids that I wanted to lose which where about all ... hate MIDS ... for some reason? ...
Dude instead of raising the chassy level had to input a higher value for something and added 10 volts ... great for now! Nothing but fun ...Broken down n' dirty dressed in rags ...Comment

(GT-EL34R-49.9vdc Linear response with harder edge.)
There's this badass swooshing sound the tubes make now whm in true bypass ... like a phaser effect ... badass ... is this due to the "linear response"? ... isn't linear like a wavelength type thing? ...Broken down n' dirty dressed in rags ...Comment

Does he mean "1960" Lead Series cab?
Find a TV/Radio tech shop or tube jockey locally and PAY THE MAN WHAT HE WANTS to bias the amp!
- you won't fuck up your new tubes
- they'll sound better with the proper supply
- you won't fuck up your output transformerComment

One option rarely discussed here, regards to playing "tube jockey" is the fact that if you are just sampling different types of tubes in a 100 watt chassis.. you can actually get by with only 2 power tubes.
Most guys aren't aware of this, but a quad of output tubes function as two pairs of a push-pull circuit..
One tube "pushes" the top form of the sinewave, while the other "pulls" the bottom form, to complete a full wave cycle top and bottom. Two pairs of tubes make a quad, so you can remove two - in Marshalls you can use either the outer 2 or inner 2 pairs.
I run my 1980 JMP with 2 6CA7's at home but if I was to practice I would throw in my quad of EL34's.
Personally I can't wait to try the NEW GROOVE TUBES' 6CA7 when I can afford to - Eyes you could plug in 6CA7's as they're pin-for-pin compatible with EL34's. My recommendation.
If you can't afford a quad, try a pair like the way I mentioned and you might really really like 'em.Comment
