I love how he just runs his hand over the knobs and puts everything at 10.

[@pavetheway]

He surfs.

[@theonewease]

That's how Randy Bachman (BTO) did it with his Sunn Model T's every gig.

[@Allguitarinfo]

Dude dimed. Every knob....love it..

[@anthonyiodice]

My god where has this channel been all my life

[@FloridaManMatty]

And why haven’t they updated with new amp builds lately?!?!

[@unhinged17]

That's what I used to do all day long! I did start off slow, but by the time I finished working there I was up to 2 full amp chassis per day. And I LOVED it!!!

[@runrabbitrun4342]

really What year?

[@muaythai4lifelife]

These vids make me want to start soldering and building amps :) even if I can only make bad soldering :)

[@TubeDepotTV]

what may start off as bad soldering will quickly become extraordinary soldering with a few hours of practice. Soldering isn't difficult once you learn the correct methods and have good tools.

[@crnogor]

Don't be scared , practise on an old , broken radios , TV , etc ! It's more easy cos is not board soldering for what I hawe still no guts ! I will recomend Y to use Silver based soldering wire , (for better and cleaner contact , with less corosion ) plus if Y can find , to be filled with cleaning cemical , inside , or if can't , use a quality paste to put on contacts , soldering iron ,etc , before Y start with contacting parts ( melting down soldering wire ) ! Ask a pro for recomandation , wich power of a soldering pen is gona suite Y ! Enjoy in future projects !

[@muaythai4lifelife]

thanx so much :D

[@MickLBrad]

Nice video. It takes me back to the days of my youth in the 1950s when I scratch built a lot of my Ham Radio equipment. Thanks for sharing.

[@sav7152]

Disregard last post about finding the right kit. This it it! Awesome!

[@ericarway]

Your wiring and assembly is beautiful!

[@fafkes]

Great to see you're back guys!

[@Burbah]

You're doing an amazing work ! Thank you very much for the tutorials !

[@josuecintron7230]

Tube Depot, I love your videos, everytime I see one of your videos I imidiately get the urge to build one of your kits (specially this one ) but unfortunately my financial condition don't allow me to do so. I love your channel. You Guys Rock, Sincerely; Josh

[@bmcash3411]

Great video and very informative. I love the roll of the knobs at the end.

[@rockerdartdude7913]

Very nice job guys. Im actually building an 18 watt self-biased amplifier at the moment and this is great to watch!

[@panospylar]

I have been watching this video for the last six months and i cannot wait to gather some money to buy the kit and make the amp myself!

[@PRSguy94]

@TubeDepotTV I'd be "road testing" those every moment of spare time I had! And building them, and testing them, and modifying, and enjoying the amazing tones that only a true vintage style amplifier can provide.

[@maryannmoran-smyth3453]

This is my kind of father and son project… Keep on rockin

[@halbertking2683]

Love the nuanced control adjustment . Dime It.

[@Chromatype]

Rob Hull! You are the MAN!

[@GUITARZ5150]

i just finished building this amp 2 weeks ago and let me tell ya this head will blow your mind. And oh my god is it LOUD. I run mine without the rectifer tube and leave the 50 watt switch on the 50 Watt position. My signal chain is an MXR Carbon copy into an MXR gt-od, into a Boss turbo distortion, MXR 6 band eq, and then into a homemade volume attenuator to switch between rhythm volume and lead volume. Jumper the inputs, and tinker until you get the tone you want. You will not be disapointed!

[@fattirevsbud]

best video I've seen in forever!

[@FullMetalHippiecom]

Great video and great sounding amp! I imagine that the voicing of the amp on the board is another project altogether.

[@matt23nyc]

You guys make it look so easy. Great work! I plan to get this kit at some point. My biggest fear is screwing something up though.

[@CRLAMB]

Fantastic sound.

[@RunawayThumbtack]

This was a lot of fun to watch. I'd really like to try building a head sometime soon.

[@lousekoya1803]

Great demo !!.........Thank you guys!

[@billyb440]

Now that was very interesting, i loved the rock paper scissors at the end, LOL

[@sebastianvergara8175]

This video is so satisfying!

[@awesometylerable]

I wish more than anything that you guys offered a video (and kit) on installing an optional FX loop. That would be so amazing.

[@Zylstra555]

What fun! Thanks for sharing.

[@akkudakkupl]

Thanks. This is some quality knowledge!

[@jimraimondi410]

that amp sounds incredible

[@greggraham8532]

Hey Rob, try using nut drivers instead of pliers or an adjustable wrench to tighten the nuts on the front panel switches and pots. Nut drivers fit the nuts securely, won't slip, and have a smooth surface so they won't scratch. Otherwise, very instructive video! Thanks, Greg.

[@jernejkurincic9050]

In my experience just tightening the driver by hand (without a ratchet) is also just the right amount of tight ...

[@MyAAAAAZZZZ]

Well done, great compliments ...

[@colefisch931]

fastest amp to dial in on the planet! I love the hand swipe to max her out! lol

[@DogDaze66]

Great Video , Thanks , Most tech guys act like they are secret scientists or some shit , Luckily Guys like you show the love and know how to help others.

[@electronicshelpcare]

excelente, very nice work

[@nerguss]

My little children after this video began to play the game - "Who will play first? (Clap-clap-clap!!!)" =) Thank's for all videos))

[@radman1102]

Cool, I'd be very interested in that amp!!

[@PRSguy94]

@TableWolfMusic I was talking about effects pedals. And I too, have a deep desire for a TubeDepot amplifier kit!

[@makeshiftJake]

Very slick amp, exactly what i am looking for. To bad i don't have the space or tools to accomplish building one. Very good video.

[@IensenMusic]

I´m waiting exactly for that!!! Please please do it!!

[@TimScottGuitar]

Oh man this is awesome!!! I want one!!! :)

[@JohanSegeborn]

Thanks, great video!

[@senescienza7465]

Good job!

[@roxstareightysix]

Inspiring, I wish i had the tools.

[@bielfotografia7824]

I was wondering which ones could I use... Thanks so much!!!

[@arjunkaul]

Great work guys (y)

[@JohnTheRipper2]

jesus, this amp sounds like a beast!

[@jjlwis]

holy crap that's awesome!

[@josegabrielgarcia8483]

this is awesome

[@jordanprysmiki5361]

Yo this is sick!

[@JRP3music]

I got a used Mesa Boogie Nomad 100. The tubes are from Tube Depot! Sounds great.

[@PRSguy94]

@TubeDepotTV Very true. If I was building the amp I would try and be as true as possible to the original tube compliment. KT66 tubes just have such a unique tone. Many people don't know this but the KT66 was a big part of Jimi Hendrix's sound. More bass than an EL34, more mids than a 6L6. Ton's of headroom, a good example being the Monterey Pop festival songs.

[@arjunkaul]

Thank YOU! You guys just built and totally nailed Marshall's greatest amp (a Fender copy nonetheless) Keep goin (y)

[@jpalberthoward9]

Oh hell yes! Great googalamoogala! This is the one that sounds like God shouting from the mountaintop! Many of us in the over 50 camp think of these as the "Allman Brother" Marshalls, violin-like sustain for days, killer for slide (brother Duane), goes with a Les Paul like beer goes with pizza! Who the hell needs pedals? Only 1 down side, grumpy grouches will be screaming "TURN IT DOWN" constantly.Not recommended for apartment dwellers or small beer joint gigs. A truly awe inspiring amp!

[@muaythai4lifelife]

Thanx so much ;)

[@TruthSurge]

Great vid! Very interesting. yeah, the ole western shootout scene. hahaha can you tell me the cost of the kit? Just curious.

[@POsomething]

Thank you!

[@holdenfarmer]

I love the MojoTone Amp Kits,they have the best of every thing you'll need in your dream Amp!The 1959 100 watt Plexi British Amp "TUBE" is the very best you can ever use!My 14 year old son and my and my self have been working on our second tube amp now,and the results are unreal.To even consideration to purchase such an Marshall Tube Amp would be in excess of 5 to 10 thousand dollars!I know there are critics out there that saying,OH NO!A fact though.

[@renemikkers6404]

I always pre-solder the input sockets at the outside of the amp. After completion, remove the whole assembly and re-install in the inside

[@grahampinkerton2091]

I built These things back in the sixties, since then i´ve moved on a bit. Semiconductors will do the Job very well too

[@ronnieparfait]

Sounds exactly like my 80’s Peavey Bandit.

[@yazd06]

Would it possible to have a demo of the amp. I know that there's one on KZbin but there's so much effects on it. I'd love to hear it - as the audio sample at the end of your video sound just great - and the difference when you play with the different parameters you added to the JTM45+. Anyway, thanks a lot for all your videos and for sharing your amp knowledge.

[@bielfotografia7824]

Thanks!!!

[@ElectrikYang]

Oh sweet! thanks!

[@brt927]

I love the way this sounds cranked. Pure awesomeness. I have never built an amp before but have a little experience with working with electronics. Which build would you suggest for a beginner? Thanks!

[@bluesdog88]

Great work guys, thank you!! Lets see the hot rodded plexi ;)

[@Richard_P_James]

Such neat wiring and attention to detail - truly excellent! So, when are you going to build a Marshall Major copy...?

[@deebee8935]

Nice build..14:52..man you are speedy!

[@opus1956]

Sweet!

[@zoomer51]

best amp ever !

[@dyakel101]

@ChrisVGuitarist Thanks! I love that guitar!

[@bobwang2837]

the last part is most fun lol

[@mauro12mdp]

Hi guys ! Your work looks formidably neat ! On the other hand, I'm building a '59 Fender Bassman model 5F6 and was thinking about doing some modifications (I'm aware that a JTM45 and Fender bassman are quite identical in some aspects): 1- Changing to a solid state rectifier 2- Inserting an effects loop 1- If I do this, should I change some capacitors values in the rectifying section for bigger ones ?? (I mean with more capacity) 2- I've heard that this might be a waste of time in a fender bassman because the difference in tone wouldn't be that noticable... And as a valve state amp, matching the impedances would be quite troublesome and I would have to design some buffer to lower the impedances and back. Anyway, I'm an amateur on this, what would you recommend ? Thanks for your time!

[@luisantoniomarrega1120]

Amigos, esse amplificador ficou beleza. Fantástico! Rio RJ

[@DANTHETUBEMAN]

full scrape,,, i like it loud,,, you had the master volume down right :)

[@MaxmadmaxRockatansky]

Great video. Hi, which name yellow tool clears the edge of the hole?

[@phayzyre1052]

Let me know when you release a kit to build a 1962 Bluesbreaker amp.

[@PoorTom]

You guys should do a video showing the tones

[@endahatmala9089]

i like it

[@TruthSurge]

@TubeDepotTV Thanks.

[@bmwm3cs]

Great Video! I wish you did a more technical one though...

[@engulfaudioable]

Very nice and informative. Where are these kits available?

[@bielfotografia7824]

Dudes!! Great job!! Just a question... What's the power rating of the pots?

[@WarrenJamesAcoustic]

I wish you would build me a fender tonemaster, I owned one and my amp tech said that looking inside it was a work of art.... or a twin reverb without a printed circuit board, the old fashioned way, unlike the modern clones.

[@TheMeJustMe75]

I would love to learn how to build my own 2 channel, twin reverb combo amp with effects loop.

[@FloridaManMatty]

A Twin Reverb with a master volume, foot switchable channel boost, and buffered effects loop is on my bucket list for DIY builds. There are some incredible tweaks and channel mods floating around online from some amazing amp builders. One day...😁

[@captainoblivious1]

This channel is awesome why am I 6 years late?

[@sameasnow]

I'm interested in the kits is this a condensed version of the video companion to the assembly instructions or the full assembly video? thanks

[@richiewichie]

wow!! awesome! What is the feedback switch for???

[@sergiocruz199]

parabens muito bom o projeto..pode informar o esquema dele?? abraços...

[@CircusHerse]

A 20 watt version would be Cool! I would like to see a half power mod for this one!

[@MPCapricorn]

Hi, I don't know if you have answered this already, but is there a full assembly video of the amp? Would be very interesting! Anyway very nice work and sound of course!!

[@DjRickeyRicardo]

Damn is love to build one

[@JackNorrisPCR]

@TubeDepotTV Very cool!

[@ElectrikYang]

Awesome Video,I would so buy the kits if i aint broke, haha. I was thinking,would it possible to make some videos on how to mod the kits you sell,using the components you provide.

[@MrQuevad]

great, great, greeeat!!!

[@PRSguy94]

@TubeDepotTV I think it's a little bogus that the american distributors were putting 6550 tubes into the amps just because there was a "high failure rate". But I quote Ritchie Fleigler "These things were not used to play surf music!"

[@snpv7679]

Hello, you are a master of the amps ... first of all this is a translation since I do not know English I am Spanish sorry..I have a question I want to mount a 6n2p and a pcl86 to make a 6w on a vintage radio chassis but I have a doubt about the mass ... gnd .... and the chassis..I do not know whether to make the chassis driver with gnd ... and if that is how I do it ... I connect all the points of mass to a single point ... it can be done in several ... or only the potentiometers and jacks go.

[@TubeDepotTV]

I think about a hot-rodded plexi kit all the time ...

[@lordraptor11]

***** i would like to see you come out with a vintage style super lead ( hendrix style) with the 4 input jacks on the front. although this amp looks nice and im sure sounds nice that master volume instead of a 4th jack kinda blows it for me :(

[@lordraptor11]

***** actually think of a hendricks style superlead with the 4 input jacks but instead of just a head make it a combo ;)

[@Trials-and-Tribulations]

+TubeDepot Great price for the your kit without breaking the bank, example I found a half for 1600 100watt, price of this kit I would have extra left over for a decent cabinet plus buy few pedals. Would you be coming out with a 100 watt kit that can switch between kt66, el34 and 6l6 tubes, resonance knob, master volume and a jose mod.

[@lordraptor11]

+DALE97DSM i disagree. for the price you could get a used genuine marshall. nothign against TD but if you can buy a genuine marshall combo amp for 600 to 700 ( and that is new) why spend almost a grand on the TD one? if you can get a used marshall head for 600 to 800 why get the td head kit? i always wanted one of the kits but the lack of funds and price compared to a genuine marshall just doesnt justify it.

[@supercrackhead100]

+lordraptor11 while it is true that marshall has some excellent tube amps and amp heads in that price range, but if you want a marshall reissue of a jtm45 head it'll run you about $2000 @ guitar center and if you want a jtm 45 combo the closest thing currently offered is the blues breaker reissue (which isn't exactly the same, 2 x 12 speakers, 30 watts instead of 45, and with a tremolo ). compared to these amps you do save building a kit from tubedepot. But you have a point that alot of people figure that a DSL40C would be close enough for less money. personally I'm building the jtm45 combo.

[@kaldesjarlais375]

uhhh wow dude, lotta work there

[@nerddujugement8334]

looks really cool. has anyone tried these? how's the price vs sourcing parts yourself? i have already assembled a mic pre (solid state with pcb) does that seem like enough experience?
