Hey guys, I wrote this thread up on my phone when I was replying to another & the work of Eric Barbour | METASONIX came to mind.
I will state the overarching goal here & then copy/paste whatever rambling idea/ wants & wishes I had at the time below:
Goal: to use the extra non-connected to Cathode electrodes of the EF86 to be able to Modulate the signal of the ef86 in ANY way I can benefit from. The design at hand is the Mic Pre section of a Tube Channel Strip. The design is REDD's 47 desk Line Amplifier. I want to be able to alter the signal in any way to squeeze out any differing tones or harmonics so when I run a vocal through the channel strips Mic Pre section (the REDD.47) I can change the tonal characteristics of the present vocal at hand. Whether this is as simple as LCR filtering or as weird & never-seen-before as _________.
*if I can flip a rotary switch and find a tonal-palette I like better than I had available from the raw ef86 REDD design... This thread & all our ideas will be a Success:")
*fyi: I fell in love w/ Shadow Hills' idea of having the option of multiple Output Transformers to fit to taste😉
Here is the ramble of ideas that one might call or find useful that ran through my head to inspire this post:
I'm using it in my Mic Pre section of my Tube Channel Strip + I want to be able to Modulate + Control the ef86 in ANY way possible to affect the sound I will have available + at my disposal... I'm trying to get everything I can from this signal... Anything + Everything... If I can squeeze even one once of tonal-change from being able to use the extra electrodes of the Screen+Supressor... As ways to alter the signal.. please lay it on me guys + gals.. the ef86 will be used as in the REDD47 design + modulated/ altered by means of the extra electrodes of the pentode. *the extra electrodes of the ef86 are NOT connected to Cathode -- so they are perfect for modulating/ altering the signal as spoken by the Great Eric Barbour... A man I idolize by taking the "odd+unused" & manipulating & altering them & their signal for added effect..
Barbour is a man that has taken random odd-ball tubes & used them to build differing designs from guitar amps ("The *******-******") and has put out a VERY successful line of synthesizer modules under the name METASONIX. His work is what inspired me to think outside of thee box when it comes to the odd + unusual😉
All n' all, we have all the time in the world + I want to pick each & every one of your brains😉
Attached is a picture that I found humorously represents how the Mic Pre in this Channel Strip should FEEL. lol. It's funny I know.. and hopefully some Comic Relief to all who stuck w/ me & made it this far in the post/thread. To you great soldiers -- I amend u😉

An externally hosted image should be here but it was not working when we last tested it.
Ok, so I'm reading AudioKarma post: "Pentodes vs. Regulated Screen--Chicken or the Egg?" to get ideas on how I would implement change in the ef86 to alter the signal and some Simple ideas keep coming up which are screaming at me telling me to try before building of even attempting to think-up new ways to do old things😉. The objective here is to alter the Signal passing through the ef86 to have multiple options of the signal to choose from. Below are the simplest of ideas:
Wiring the ef86 up as a Triode, Tetrode, & Pentode -- & being able to switch through the differing outputs.
Modulating either the Screen or Suppressor w/ Feedback, Side-Chain, or even the option of taking the signal from a different section of the Channel Strip & injecting it back into the front-end via the Screen or Suppressor either as Feedback or as an effect.
*This Mic Pre module will be housed w/ a Compressor/Limiter based on the LA2 +/or the Vari-mu designs & finally followed by a Inductor-based passive-eq based off the old Pultec design.
. : *the goal is to have a 4U racked unit (the channel strip) that will have many of its componry parameters varied &/or Modulated for tonal-change or effect (fx).
. ; **the Goal of the channel strip is to create a design where any useful parameters/components can be altered to acheieve a different sounds than what would currently be available.
. ;***the unit will be my go-to prototype to be able to try out different options & yield exciting new results all-while being assembled in one 4U unit. ie. A channel strip w/ options.
PS. I don't see boundaries when I think up these "ideas" -- I only see opportunities to achieve a sound never heard before ...& hopefully useful to a Vocal-take. This Idea came to me when I realized the Mic Pre I built for my high school pal's studio was being used to track Hip-hop during the day to Pay the Bills -- then used at night on the owner's own Rock-band. ie. The more flavours we can get out of this design - the more options there will be to sculpt the Recorded Vocal.
....Got-it Guys?
*I know my posts + threads seem impossible, inefficient & just downright silly... But hey.. if there is a way to alter the Recorded Signal + Sound in ANY -- I want that option available + wired-up as a switch on the Front-Panel so the Engineer running the Recording Session can quickly have access to as many different tonal-options we can think-up + then fit on the front panel. ie. The resulting design would have a plethora of (signal-chain) options in how it both would take-in the audio, process it thus giving the user endless-control over the signal + most importantly, an enjoyably-fun hands-on-hardware experience that could result in hour's of experimenting to find new sounds :")

You can make this infinitely variable with a triode-pentode blend control:
You can increase harmonic content by leaving the cathode resistor unbypassed and connecting the suppressor to ground, not cathode. Add a pot to allow a variable amount of cathode bypassing and you have a variable harmonic distortion control.

As this clearly isn't about sound reproduction maybe it would be better in Instruments & Amps forum?
Moved to I&A..
DF96, kevinkr... Where did I post this in!? I thought I had posted this under "Vacuum tubes.." ..am I not correct?
Merlin how should I implement this into the REDD47 Mic Pre -- any of the various builds that can be found Googling: "REDD 47 Mic Preamp Build" -- there is a great one by "alexc" on Group DIY. He actually has a Fairchild 660 build I'm DYING to run the REDD47 into... I thought this Pentode-2-Triode mod would be cool 😎
Here: JBB's build is Turret which is more my style (p2p+turret). He kept it more original w/ NO regulation, AC-heaters, I don't even think there is a Real PAD or 48v Phantom.. http://groupdiy.com/index.php?topic=53650.0
While "alexc" had many add-ons + upgrades. Alex is more an engineer. JBB's build is more like something I'd do... Since I'm great at building -- & not very knowledgeable about the Math/ Physics behind engineering a design as AlexC did/does. Hope this helps some
