The ORIGINAL Eric Clapton Blues Amp - 1964 Marshall JTM45 BLUESBREAKER (Repair, Analysis & Demo)

In this video, we'll look at a real historical HONEY of a guitar amplifier. This is NOT a reissue! This is an ORIGINAL 1964 Marshall JTM45 Super Tremolo Amplifier Model 1962, known affectionately as the "Bluesbreaker" after the John Mayall album "Blues Breakers", on which a young Eric Clapton played. It's always nice for me to see amps like this because so few of them exist, and also because so few of them exist in my part of the world.
The owner of this amp is also the owner of the Fender Champ I recently serviced. We sent the original speaker in that amp off for a recone at The Speaker Workshop due to a rubbing voice coil. While picking that amp up, he decided to bring along his Bluesbreaker, which has been sitting for over a year untouched, due to a badly punctured Celestion G12 T731 speaker, which apparently came originally in a Selmer amp? We are not sure. In this case, he wanted to avoid a recone if possible, so I'll show you how to fix a speaker puncture using a hot glue gun and we'll open up the amp and examine the guts. Then we'll plug it in and jam with some Glen Miller custom korina Gibson Futura and Flying V guitars.
This is the WORST speaker puncture I've ever attempted to fix using this hot glue method. If you DO need a recone on a vintage speaker, I highly recommend The Speaker Workshop in Fort Wayne, Indiana: bit.ly/RECONE

Some of the best greenback speakers I have ever owned had glued tears like this and they sounded amazing. I wouldnt recone it because the voice coil would be changed and the new cones and voice coil wouldn't sound as good in my opinion. Nothing wrong with a glued cone. Nothing at all.

I'm a Marshall guy in the UK but do lots of others . I also design and build combos that Marshall should have made back then , convert Valvestates to tube , that would include Trainwrecks and Dirty Little Monsters of course but also add my own touches when building an EL34 out amp by chucking in an EF86 as a second preamp tube . Just restored a Hi Watt Custom 100 fitting new caps inside the old cans and swapping out a couple of other components . I'm now converting a Vox 67 Traveller Solid State to an AC4 type combo using as many original parts as possible . The cabinet is the same as the AC10 etc. The construction of the Marshall and Vox cabinets are similar in that the front baffle is one piece bolted in all around. A saw cut takes the grill cloth and tolex with a length of trim wedged in to finish so not that easy . It can be invisibly repaired from the front using a darning technique by using butterfly plasters to hold it in position . Probably the hardest job to do on this as the more time taken the better the results . The Mullard mustards are normally all good but I have the spare 0.22 uf ones swapped out with Spragues in your example . I use plain toilet tissue and Titebond water based glue to repair cones and inner tube rubber solution to repair surrounds . This simulates the original manufacture of the cones . Having repaired much worse, the proof is tapping the cone all round and checking the pitch with an app . As far a strength is concerned there is no doubt that the single ply toilet tissue and re paper macheing the original paper and integrating it works good and my preferred method . When repairing the rubberised surround use the but end of artist's paint brushes the match the suspension valleys . The hardest areas areas are behind the basket frame .

Nice guitars and chording by Dan !! I have #7032 ~ very similar down to the missing handles , broken rubber piece on the cloth power tube retainer and repaired speaker ! My speakers are the original Silverdale Rd gold label Celestions. On my amp the tremelo only works on the #2 channel. I use mine @ 110v through a controlled voltage variable auto transformer. Lucky to have the voltage selector 110v on top of the power transformer. Congratulations Dan on moving forward with the restoration !! Since your grill tear is in front of the speaker the grill can be sewn with a curved needle and thread without having to remove the baffle. I had it done on some white grill pa cabs with some grey and white thread to match the color with very good results.

I always use 2-ply toilet paper where you peel it back to have thinner pieces of one ply. I thin out some white glue then dip a small paint brush into the glue and paint the toilet paper onto the cone. Works like a charm! Just add a touch of spray paint to make it match up the color of the cone.

[@seansweeney3532]

@Ringo Starr if you have a favorable tear that works great. since wood glue will really grab pulp paper... but If you've got a situation where you actually have to put a little bit of tension on the repair and experiment with the as you're doing it the hot glue is probably the best way to go

[@jordangibson695]

Where this model really shines is the great mid hump you get from those KT66 power tubes. The cleans aren't that bright, especially with humbuckers, but it overdrives great. KT tubes require a lot of filament supply current compared to more modern power tubes, so it's not easy retrofitting them into amp where the power transformer wasn't designed to handle them. I've tried and have usually had to resort to pedals to get that sound.

[@jjcollins]

Wow, absolutely awesome video! And great job on repairing that speaker! That amp sounds GLORIOUS! As soon as you guys started playing, I'm thinking "jump the channels"! Of course you eventually did, and it was HEAVENLY! : ) Clean and dirty, it sounds amazing. Awesome work as usual Brad.

Okay maybe on a lesser amp to experiment but just a thought.

[@TheGuitologist]

The stuff I showed is probably very similar.

[@shawnglass108]

Clapton bought his in late 1965. late November or early December. The specs on these amps were in a state of consistent change. That’s why there’s no way to know what the exact specs of his amp were. He bought his right as they were switching to ceramic speakers. Most people believe his speaker were alnico but I’m not so sure those 15 watt alnicos could’ve held up to him playing it fully cranked night after night. Although it’s a 30 watt amp it puts out closer to 50 when cranked and that’s how Clapton says he kept it to get his sound. Any opinions on this? I’m certainly no expert. I have a Marshall 1962HW. It’s my favorite amp that I’ve ever played. I use it with an attenuator though.

[@Rikk_Klaww777]

Not a big fan of Marshall amps...but after hearing this i really love this amps sound. So warm and open...that cranked crunch sound is not fuzzy at all.! Just crunch perfect..very very nice if mic'd up..💖👌👍🤘🤘🤘🤘

[@PaulaXism]

Brad.. just a FYI .. the 1960's Mullard ECC83 made in GB with yellow lettering denoted higher quality. Through the early 70's the yellow ones were made in Holland by Philips at Eindhoven. The UK made ones reverted to white paint and the HQ ones had an added yellow spot. That lovely yellow GB tube was made in Blackburn Lancashire. I have a full set of 3 in my 1967 Laney Session 50 and they really cook.

[@sillysambo1000]

Philips owned mullard since 1927..they opened the plant in Blackburn and other places in UK..tubes made in Holland or UK were all the same company...mullard ceased to exist in 1927 except in name..swallowed up by Philips

[@LightningDogg]

Wow that amp sounds great! Anybody who's ever used a hot glue gun knows what a PITA it is to control the flow. Once you push on the trigger it starts, but it continues after you let off the trigger. Then you have to deal with the "strings" that hang when you pull the tip away. This is a job well done. Edit: Forgot to mention those 2 guitars. DAMMIT MAN!!! Absolutely beautiful.

I use tissue paper and Damar Varnish brushed on with soft artist brush for cone repairs like that. The varnish is very watery and dries quickly . The tissue is a single ply split from Toilet paper, Very thin but reinforces the repair. The strips only need to overlap the tear by about 6mm.

I was going to write this off as a crappy amp until I heard the flying V plugged in. It seems the guitar pickups really make a difference with this amp. To bad we didn't get a Zio appearance to see how that sounds through this amp.

Do you know the name of the studio it came from? I am from Rochester, and was the marketing manager for ART for many years. I may be able to help trace some of the origins of the amp.

I wish i had this kind of talent. I wish i had that kind of amp too....damn thats sweet....both of em

[@gumbomudderx7503]

Man, that thing bridged sounds amazing!! You friend there definitely has some cool toys!

[@monmixer]

Cool, thanks, the sub was with that one. I'm not only a guitarist I'm a sound engineer and I have my own little club and street fair sound and light rig. Thankfully I have never blown a speaker but if I do I will try this. Had a bass port fall of of a QSC sub. Gorilla glue fixed that stringer than it ever was.

Who's the owner? I love how jazzy he sounds!

[@williambock1821]

Thoroughly enjoyable. The dulcet tones of well made instruments. Still want that lunch box amp! Cool flower cabs, too. Never got to play an actual old Marshall so I converted an Ao35 into an 18watt lite with a new OT. I was pleasantly surprised with the clean tones! Im stoked about the overdrive ,of course.But with a good speaker, the cleans can be just as inspiring as the blackfaces I’ve tried. It’s a great amp.

Very cool!!! I’m completely clueless about the tech side of amps, but I love this channel, always something interesting 👍!

[@performanceedge8758]

Love this channel. If you had to only have one amp to play blues; what amp would it be?

[@digitel303]

great video love the tone of that Marshall

[@robertthrelfall2650]

Would the added weight of the glue on just one part of the speaker cause the coil to rub? If so, it may be a good idea on a large repair to add a similar amount of glue 180 degrees from the repair, kinda like balancing a tire? Dunno, just a thought. You would think there would be some kind if doped paper fiber type product or maybe a structural paper tape for these types of repair.
