Can you mod a 5010 the same way or is it not worth your while
Excellent , why wouldn't You make it better. I love modding
I am surprised more pros like you and Alex don't do this more often. The power and capability of modern FREE circuit design tools (schematic, components, PCB board design, validation) makes that part straightforward for those with core design expertise. But now every firm making PCBs accepts Gerber formatted PCB design files and can produce boards for $5 to $10 a piece. With that kind of pricing and 1 week turnaround, it is economical to prototype your own design thru a few iterations, then after nailing down the design you can order a few extras for spares. And you can save the CAD design and Gerber export and use that to get a board made 20 years from now.
A few comments/questions on a technical nature: 1. How loud of a signal is necessary in order to drive the first gain stage into audible non-linear territory? 2. When you changed the cathode resistor on the first gain stage but left the bypass capacitor the same you increased bottom end amplification (down to 87Hz vs 285Hz, based on crude calculations). 3. When you added the 22uF fat cap you increased gain to a stage that you kept biased as hot. IME, this runs counter to any goal of reducing fuzziness. What do I hear? I hear the increased low end in the voicing and a fuller sound overall and find it to be an improvement. I don’t hear any issue with fuzziness in either clip though you didn’t do any heavy riffing on the bass strings at the 12th fret with the neck pickup to tease out any potential problems. This was also helped by the fact that you weren’t using the normal channel which has the 330uF cathode bypass and 22nF coupling capacitor; not to mention that it doesn’t have the bright and treble peaking caps to help mask a fuzzy bottom end. Personally, I’d go with 1.2k at the cathode of V2A (still bypassed with 22uF) and lower the V2B cathode resistor to 47k; but that depends on whether clipping at the cathode follower is an issue and whether any noticeable compression that may result is desirable. I definitely endorse lowering the bypass frequency at the first gain stage of the high treble channel unless blending is your thing, in which case I think Marshall’s configuration of the normal channel also deserves some scrutiny. I love your videos and all the wonderful things you do for the DIY community. You are a great source of inspiration!
Alex knowlege is a sleeper until now and used to get the 2 of you confused before I got to know you both on the Internet and both of you have done amazing things and a big fan of both of you ,guys keep it up man converese with your knowlege and hope to see more great things from both of you cheers guys !!!!!1
Simply brilliant. I'm impressed as hell.
What an awesome idea! Did I miss a link to the bill of materials? I see that the boards are $150. Wonder how much the components add up to...
Love what you do to these Origin amps! How possible and how much would it be to do this to my Origin 20 head if I mailed it to you from the US? I'm not an amp DIYer...😅
Oh man and i just got an origin..... hmm
Can you please do this with the DSL1?
would need more info about the board dimensions but sure
I had a DSL 40C that I had laying around that I was going to sell. My other amps are a Bogner Ecstasy 101B, a Fender 6G3 Deluxe I built and a ‘65 Deluxe Reverb that I gutted and handwired. I think I’m going to keep the DSL with the rest of the stable. Sounds much better with these mods! Thanks for sharing!
Finally! Nice work fellas. The board is labeled 20\50. I assume this will fit either amp then? Ordering!
direct drop in for both 20W and 50W
Cool set up Jason! I bet your amp building is going very well every one knows about yours and thats great to see! I know that you worked very hard for that cool stuff. Take care brother.
This is absolutely genius - origin prices will increase on the second hand market 😅
Alex is an incredibly talented man, I own one of his amps ànd I love it!
I already used one of your drop in boards, the jj junior board 😁Well, guess I have to get another Origin.
The mad man finally did it
Nice work Jase (and Alex!)... sorted. How's that Gretsch!!!
This is amazing. Great work! Please sell this drop in JCM800 PCB with a bag of all of the parts and pots needed to populate the board! I'd pay extra for that and buy immediately.
I think that would be an attractive offering. I'd grab one of those as well.
Ingenious. Sounds wonderful.
Amazing idea. This is exactly how an electric guitar is supposed to sound. I would change nothing to that sound.
I liked the playing just as much as the amp!
I'm betting next week you're going to do a "DIY mod board" for the Line 6 Helix? After all, Digital is superior to analog in every manner. Just being me. AND fwiw; this is a brilliant idea. I am hoping you do several videos on "populating" the board. ---Ben
Excellent work and fantastic idea. I will again suggest a "highly detailed" how to solder video. A video showing ALL the proper gear, how to avoid overheating joints and how to avoid cold joints. A video showing that you CANNOT use a solder pencil, you must use a proper regulated solder station with an excellent thermostat. What type of solder to use and what to avoid. How to use a vacuum solder removal tool and how to use wick to remove solder. Just my suggestion. Every amp builder thinks that "everyone has an ability to solder" and "soldering is not that hard." I think it is time for pedal companies and DIY amp companies to be honest and admit that soldering is a distinct skill set. Please do a detailed video. Thanks-----Ben
are they going to make an Origin 50 version? or could it be modded to drop in?
works with both 20W and 50W versions
Jason, you’re the best. Thanks for all the info you’ve put out on these Origins. Doing the Rock God’s work for the Marshall enthusiasts!
Thanks!
We need more of these PCBs! Great job you guys!
great idea! the price is a bit steep for me though, especially compared to the other evolve diy project boards.
Great work Alex. Someone has a new Gretch!!
Sounds ok doesn’t it!
@@HeadfirstAmpsI was having NAD until I realised that it was my amp 😂 Awesome playing though as always! that loop is super transparent though right...? 😂
G'day, what speakers are you playing through? Sounds really good 👍
G12M Greenback
Alex is amazing - he's worked magic on my M.I amp, and my band-mates JSX and both sound incredible! Highly recommend his work ... and a hell of a nice bloke, too :)
The only thing missing is a decal with the number '8' that you can put in front of the number 20 so the logo that reads Origin 20 reads Origin 820, 😇
Nothing like a little but of the Cult to start my day!
That's epic, Auzzy ingenuity!
Alex is an actual freak at what he does
EXCELLENT CRYSTAL CLEAR VIDEO! 👍
I actually did a transformer switch due to the DAGNALLS CATCHING FIRE>>>>>SO back then I got Classic Tone and they are wonderful, but sound wise...NO REAL DIFFERENCE
MERCURY ARE WILDLY OVERPRICED!!!!
Jason, do you have an EU partner for the pcb boards? I would like to have a board, but don't want to ship all the way from Australia.
Look up Manta Electronics, Italy
@@HeadfirstAmps Ty so much!
It’s normally only a few weeks to ship from here to EU
@@HeadfirstAmps it's the customs mate, incredibly frustrating and slow from outside the EU. I would not have any problem even with longer times
Great work. So many guys out there want to mod these amps for more gain and they end up sounding pants after the mod. They are so good stock, why change a good thing. I think even the best high gain mods with these are always a compromise, and you lose something. Keep up the good work.
Dream amp
The breakup on that amp when you demoed it was spot on just like you want the amp to respond
lol build quality notwithstanding, the MAVs sounded better. More "Marshall" I would honestly get a Hammond or Heyboer for a Marshall iron. Mercury seems like great folks and all, but price/performance-wise I won't be looking at their offerings for Marshalls. Maybe 5150s and the like.
MARSHALL stopped using Dagnall in the early 2000's because they were making transformers that caught fire!!!
Great playing
Oh damn that tele sounds shit hot
50+ years on, and Jim Marshalls creations are being kept alive due to the respect and care given to them by passionate ppl like Jason Tong ...I salute you brother.
A year late, but the chances of someone modding with almost identical Carbon Comps is probably rare, looks factory. Sweet! Love your vids man.
