You need to bias your amp with every power tube change.
Back in the day, the repairman simply pulled the bad tube and stuck a new tube in its place. No biasing.
Feathers have not been ruffled...gotta step it up a notch...
Tube swaps will not 'transform' your amp.
You go with that! Notice the use of the word transform…Interesting feather ruffeling topic. I have enough real world experience to know that there are tubes I like, and others I pulled after a day or two and reside in boxes. I have 6L6's 6V6s, EL 84s, 12AX7s, AT7s by the dozens.
I have read that leaving the standby switch engaged and turning off the power switch may help drain the caps, does anyone know if this is true?
He he, I’m looking forward to the day in six months, or a year and six months, etc, when someone on the internet stumbles across some posts in this thread without understanding the OP context and furiously takes a poster to task.
I find most gear discussion very much like wine discussion. The major varietals are distinct; Telecaster-Les Paul, or Princeton-JCM800.
But then we get to which side of the road the grapevine is on, French or American oak barrels, hints of this, notes of that, cork stopper vs screw on cap, yadda yadda yadda. Everyone tastes, hears, and feels something a little different. But most often it’s what they are told to taste, hear, feel.
Is your avatar a Crumb comic?Tubes should be hard to pull out if your fingers are soaked in chicken or motorcycle grease. If they come out easily the sockets need tightening. Clean the grease off the tubes afterwards unless you like your studio to smell like Church's or Hank's Happy Honda House.
Other parts warm up besides the tubes. Resistors drift, some caps too, heck the whole frigging thing including the speaker gets warm including the player and hopefully whoever's listening. Neighbors might get hot under the collar.
OK, but I use a modeler and I want that smell in the studio. What to do?Clean the grease off the tubes afterwards unless you like your studio to smell like Church's or Hank's Happy Honda House.
Having worked at G-K for a few years back in the early 90's, I got to know Bob a bit. I see him at Home Depot every few years. Of course I heard this story. There's a recent interview with him by Mitch Gallagher on the Sweetwater web site. I don't know how to link directly to it. The story of that amp is pretty incredible. I find Bob refreshingly straightforward and humble given the impact of his designs on the bass world.Carlos Santana's amp (made by Bob Gallien) at Woodstock
Graphs! I need graphs!I wonder if ‘myth ridiculousness’ can be plotted and if so, is the growth exponential?
Awww. You need more!Some of the last of my old junk.
I'm missing a few 6L6s and a matched pair of EL34's. Hey... I slipped in the shower!went to the proctologist
Albert King too... I saw him live at Tipitina's way back in the day and couldn't believe the sound he was getting out of those Acoustic stacks... with horns! like an old church pa system))"You just don't get dynamic response and warm tone out of a solidstate amp!"
B.B. King: "Hold my beer!"
"Only tube amps provide a harmonic distortion sound!"
"I get my distortion mainly out of pedals!"
"Tube amps with mastervolume don't provide smooth overdrive, you need poweramp-saturation for the right overdrive!"
"If there is a single transistor in the signalchain, it's not a real tubeamp - you'll hear the difference!"
They sound good right away.Top of the season to all of ya's! Let's take on all the misapprehensions out there. Keep it simple, or explain away!
First up, tubes do not need a warm-up period to sound 'better'. They don't 'breathe' more once warm, nor can they create 'space'.
How long do they need? A minute? Until they work?
A tube amp that needs twenty minutes to warm up also needs service.
