    Your videos quickly became a collection of references for me. There are tons of amp tech videos out there with 75% whining and cursing and 25% showing the solution. I like the pace and detail of your explanations. As a software engineer I understand the benefit of whining and cursing but I tend to flip the percentage when possible :) Anyhow, can't wait for the next episodes. Looking forward to hear your experience and advices on NFB and more on ground schemes. Great work and thank you!

    I really like the 50KL middle pot “mod”. Some of the JMP’s I’ve seen have had a 50k or 100k with a resistor to get it down to ~25k. A 100KL pot is a good value if you’re after an almost “Tweedy” sound.

    I like to leave the bright cap off the lead or bright channel and put a small one to taste on the normal or bass channel, your favorite boost pedal will let you know the size of cap, use said normal channel with pedal and bright cap, jump to lead channel with no bright cap tones from sweet cleans to one wire mod with NO rasp!!

    Lyle you got a thumbs up/like for the half n half ad at the start. I'd have hit it another 2-3 times for the rest of the video if it would do any good. Like what your talking about with low volume on the clean channel, Mick Taylor (YT channel That Pedal Show) did a vlog some months back where he set up the shows 1987x re-issue clean, ran it against the shows house deluxe/Super reverbs (Dans 61 AC30? can't remember the other amps) and it was clearly a matter of taste Vox/Fender/Marshall which sounded best for gorgeous sparking clean tone.

    Nice video! I'm not sure why you chose a PPIMV over a traditional Post-Tonestack Master as PPIMV plays on the NFB, but personal preference.
    As far response back to Pete and what things actually do....I think the best way to do it is a good video, well thought out how play the same loop and changing the settings on the amp and folks here the difference while communicating to people what the changes are and why it sounds the way it does.
    I think the best way to do that is to build up an "All Access" version SIMILAR to what Nik at Ceriatone put together, which includes all the different variations including PPIMV as well as selectable rectification between Tube and Solid State. Only changes I would make is ensuring values, and deciding on cap values across the B+....would it be 50/50/100/50/50....100/50/50/50/50, 50/16/100/33/33, or some other variation?
    I'd like to twist up my own variation of this All Access version, but personally would get rid of the PPIMV, FX Loop is good between Preamp and Phase Inverter and insert a Master after the FX Loop! I'd probably do a 50W version and consider a 20W version with 6V6s. Looks like the NFB is on a 3 way so you can set the value, but not tap, so I'd probably add another switch to select the tap applied also! It would be easy to add the Rhoads MOD also on a switch or Push-Pull just by lifting that 470k resistor and moving over to the 68k/68k split of the Bright Input!! Man, would that be a Swiss Army of amps?!?? lol One could add the Jose MOD also and defeatable voltage clamp and zener clippers!! Oh, and if 0-120 taps and 100-240 taps, you could add a Virtual Variac also!!
    I'll have to think about this and what B+ filtering scheme I would use, but sure would make the video like you purposed easy....just loop something and videos of the different changes and for the different years...67, 68. 69, etc!! Look forward to the video and you have the gears turning!! lol

And then how do impedance selectors work? The old push in make sense but the rotary knob is confusing to know what chooses what.

    I never really understood the logic behind hot biasing?
    I always find there's a sweet spot at 70% PD and there's an equally sweet and less "thick" spot at 55% or so.
    My old AC30CC was biased at insane levels even for a Vox. Fender's all sound great at 55%.
    A great quote I read recently somewhere, "I bias my amps until the tone noticeably thickens up: I nearly always like just before that point."

      Presence IS the ground point of the phase inverter, and the phase inverter and screen nodes are inside the negative feedback loop. So all together to chassis right by the Presence pot. See the video linked in the description.

      Flyback diodes to save output tubes from arcing. Modern EL34s are prone to it. Doesn't affect the sound/feel. Just keeps the magic smoke in.

      @@PsionicAudio Thank you. I immediately watched all three. I have a dream amp: A very custom 'Hiwatt' with top of the line KT66 output tubes. I also like your idea of converting the presence knob to upper mids. Those stratospheric high frequencies are insane. What I want is a very high headroom, hi-fi pedal platform. I also want multiple outputs for daisy-chaining and stereo W/D/W effects. Like, both an effects loop and a line out, and two 16 0hm speaker outs. Sound City and Hylight both do this, but Hiwatt does not. Everyone in the world uses the Marshall high-gain thing, or the fender, or the Vox thing, but I simply love the uniqueness and cleanliness of the Hiwatt sound. I do not like high-gain or that ancillary 'velcro' distortion thing - to me it's just not a holistic aspect of the musical soul of tone and texture. I want cathedral bells in my 3-way 2.1 system. Hiwatt as it is, is just not exactly what I want. It's a great (the best) start, but I want my own original, unique thing. Watching you makes me feel very comfortable and confident that you are the brain surgeon to depend on and turn to in 2022. I'd want nothing but the very best of everything. I was reading about Gold Lion KT66 tubes today, and they 'sounded' (in the written description) perfect. EHX KT66 'sounded' like a close second. "A huge sound with rounded bottom, smooth top, and compressed upper mids. And I see no point in bright caps. Who wants to ice-pick their audience to death? What's the point in competing with cymbals? I want my guitar to sound like Cathedral Bells over the world's finest home stereo system from a Deutsche Gramophone Record. Anyway, I love your videos! I am not a tech. I am a composer/producer who happens to play guitar (for 50 years now). I sit mesmerized by your show. I have seen others' but you are by far the best of them. Keep them coming.

      @@PsionicAudio Interesting. Why wouldn't you use KT66 instead of EL34 to get away from the Marshall sound? It is my understanding that it is the EL34 that gives the Marshall its 'nasally' sound. I got my info here: www.thetubestore.com/kt66-tube-review (Maybe 6L6 or KT88?) I like the Fender sound, except there is a 'tubey' (tubular?) upper-mid that I do not like which is very specific to the Fender sound. I've owned Marshalls, Fenders, Seymour Duncan convertible, Mesa Boogie, I've played through Celestions and EVs. The system I am designing will use a mixture in different cabs. All Alnico Webers of the various flavors built to my specs, as will be the cabinets themselves. Each cabinet built for a specific speaker type. I hope I am not wasting your time with bothersome nonsense, but I have been working on this concept for years, and how to create an extremely unique system that gives me a sound all my own, as I have described to you.
