@@UncleDoug I had a good ol belly laugh on that statement. and reminded my of my youth. While attending HS in ElPaso (go Rockets), I was curious(and 17) and drove my dad's van to one of the red-light districts in Juarez with my stepbrother. We parked and were immediately approached by a guy selling "real" diamond rings. He followed us down the road while dropping the price with every other step. He "proved" the authenticity of this incredible gem by scratching the windshields of several cars. "look - real diamond man - scratch - gouge". We passed on the deal of the century and decided we better leave or risk the windshield of the van to be used as his new favorite demonstration vehicle. I later learned that it was customary to pay local kids to watch the car. Later still, I was told they wouldn't actually prevent anything from happening to it, but you did get an exuberant account of what happened with full descriptions of the bad guys that could describe 99% of the native male population. They, of course, would still expect to be paid the final 1/2 have of the negotiated "watch" fee.

Example; Vox Sovereign 4X12 with 2 Vox Blues and 2 JBL D120F speakers. I had no idea how good an amp can sound until I tried this combination. This is just the tip of the iceberg. Try other cabs and speakers! Stunningly beautiful. Thank you Doug!

It's a tone beast! I couldn't have done it without your videos! You may know this, but the Blonde Bassman was Paul McCartney's primary bass amp for most of the original Beatles recordings, and on the later albums, they would fight over who could use it. After the Beatles broke up, George Harrison used it for years. I'm amazed that someone found one at a yard sale!

@@UncleDoug I understand, in my opinion there is nothing sweeter than the pure tone of a well amplified instrument. I do enjoy the sound of a guitar. But the amplifier has the power and the ability to add another dimension. Not just roar and rumble, but a real singing feedback that can be manipulated by the player. That is what distinguishes one amp from another. A Fender has a signature tone, that is different from and Ampeg or a Gibson or a Valco. If you wish to get pure clean tone, then the solid state amps are the way to go. With vacuum tubes there is a transfer of electrons across a distance that can not be duplicated in any other way than in a bottle. And that is why we love them.

Some great races. Also some wild crashes. The cops would bust it up every so often. Your interest in hot rods and tube amps is interesting. And my point about pushing the tube amps is similar to hotrods. You do not build a street rod to cruise along at 55mph. And if you have a guitar and an amp, you crank it up and see what it can do. Turn the amp up to ten and control it with the guitar.

I, can't tell you how grateful I am that I found the guitar community on KZbin. It led to me buying my first guitar, first amp, and first tube amp. It's about 90% of a Marshall circuit from what I understand. A Laney Cub 12R with a spring reverb. I knew I was supposed to be a musician from a fairly early age. I just never went for it because I was strung out on drugs from 15 to 30 years old. It took me another 7 or 8 years to realize the things I liked. Hobbies, etc... And since I actually had money in my pocket instead of drugs up my nose, I could buy guitars and amps and pedals and tools and things to build pedals and amps and guitars lol. So glad I got clean. I wouldn't be playing today if I hadn't. I just wish I had started early in life. I'm sure I'd be an, incredible player now. Oh well. I'm having fun again and that's all I care about. After the death of my daughter and only child in 2014, there was no more joy. Playing guitar is the first time I've experienced genuine joy since the death of my child. I'll never quit playing. I'll never sell my gear. Never. I feel like my life depends on it. Same goes for my dogs. They're a huge part of why I'm still here and haven't checked out. So I won't ever be without a dog for the rest of my life. They are that important to my well-being. Just like my guitars.

Deoxit > other stuff. I learned this directly. Had a scratchy pot and didn't want to spend a ton on Deoxit so I bought some electronics cleaner from the auto parts store. Nope. No change. Still had a scratchy pot. Over a year later, I finally decided to buy a can of Deoxit. Sprayed the pot, worked it a few times and it was completely quiet. No more scratchy. That's all I needed to see to understand why Deoxit is better and costs more than the $3 can at the Auto Parts Store. Being an automotive tech & mechanic like you, Uncle Doug, I should've known that there was a reason Deoxit is 5x the price and why everyone praises it. It's a tool that works. In the automotive field, when you have a tool that makes the job that much easier, you buy it and don't worry about the cost. I should've known. I'll know next time. Kind of like the StewMac Z-file fret crowning file. I paid $92 for it but it's going to allow me to do $2100 worth of work to my 7 guitars. Being able to level & crown the frets myself is going to save me sooooo much money. Thankfully most of my guitars were leveled and crowned at the factory so there's only a couple of frets on each one that need dressing. Enough that I could do them 1 by 1 instead of a full level and dress and save some height on my frets by not filing them all down when only 2 need work.

I want to tell you about a little trick that's almost always used when connecting a potentiometer like a rheostat, i.e., when you use only the wiper and one end of the pot, as you did when installing the bias-adjust pot. The trick is to directly short the unused end of the pot to the wiper with a short piece of wire. If you think about it for a bit, you'll realize that under normal operation, it doesn't change anything. However, in the case where the wiper loses contact, either momentarily or permanently, with the resistive strip, instead of the resistance going to infinity, it goes to the full value of the pot. Sometimes, this difference in behavior can save a circuit from damage, and sometimes it just makes the pot quieter if the pot is a bit dirty. This is just a little, zero-cost bit of sophistication in circuit design.

Uncle Doug, I would like to sincerely thank you for creating this fantastic channel. You are a fountain of knowledge, a generous and gifted teacher and a welcome respite for me during the past year. You see, last may my lovely wife was diagnosed with a rare form of cancer and she is sadly in stage 4 with that cancer. I've had to quit my job as a zookeeper, which I loved, to take care of her and she goes through surgeries and chemo.I'm glad to do it, but it's hard in many ways. I play guitar when I feel inspired, but about the only thing that I have enjoyed lately, has been learning how to repair and build tube amps.You. are responsible for the majority of that enjoyment, interest and the confidence that comes with the knowledge of knowing that I'm learning from the best. Sorry for the long and personal note. Thank you.

@@UncleDoug It's an honor to hear from you. Thank you so much for your words of support and kind wishes.. Our next step in her cancer treatment is to go to San Diego for another surgery and HIPEC chemo treatment. The cancer is so rare that there are no specialists in Northern California. When we return, and when I have some free tlme, I look forward to finishing my first full amp build, a 59 tweed style 4 x 10 Bassman. Then I'd like to go over/restore my old Marshall JMP. Until then, I will have a week or two while we're in the hospital to binge watch the remainder of your fine videos. Best regards and keep up the great work.

Great restore! I never thought about putting the fuse after the power switch. Typical electrical install would be to put the overcurrent device prior to any switches, but OC devices typically have a means of disconnect. The little fuse holder could definitely give someone a jolt if they tried to put a fuse in with it plugged in. The Nash is amazing!

I might have said this somewhere else on this post. But I remember watching the bass player for a group called, The Classics (forerunner to the Classic IV, of "Spooky" fame) get up on his 1961 or '62 Bassman and do the twist, as my brother climbed aboard his 1960 Fender Pro and the lead guitar player jumped up on top of whatever Fender amp he was playing ... These amps were made to rock! My '62 Bandmaster is still sounding like Heaven in a blonde tolex box!

Oh my...talk about a time machine. I had the same amp for several years in the mid 70's but I let it get away. I also had a 1960 Rambler American in the mid-late 60's. It had no horsepower...instead it had flowerpower....a racing stripe made from stick on vinyl flowers. That one went to the junk after I hit a street sign, fire hydrant and a tree...in that order.

I worked as a professional service man for many years, repaired all kind of home electronics. But the soldering iron has been cold for many years. Until I watched your videos and was inspired to plug it in again. To fix some amplifiers for a friend and so on. I even bought an oscilloscope, variac and some other nice to have stuff. And you know, it was fun again. The big difference is that I don't do it to pay the bills this time, but as a hobby. That's how it started many years ago, the circle is complete.

What a find, a lucky (and astute) buyer! Go ahead and tell the price, I am always happy when someone finds a gem at an unlikely place. A friend found a original Fender Tweed Concert amp on the curb! A got a $25.00 1964 Gibson RVT at a yard sale worked fine, original owner. Edit: this is now the end of the video, great job UD. If I ever find another old classic amp like this one, I'll send it to you providing you find it worthy, it's like a never ending scavenger hunt. It would have been nice to have seen the missing Bassman cabinet but there are several companies making perfect reproduction enclosures. What a keeper.

Uncle Doug, thank you for posting this video. I’ve owned a 6g6 with matching 2X12” cabinet for 40 years. I’m the 3rd owner and knew the original owner. I gigged with it for about 7 years in the 80s and it spent a lot of time on “drunken chimpanzee’s” benches. Finally had it restored by a competent tech in 2002 but it’s had little use since then and spent its happy retirement in climate controlled storage. Fired it up recently and noticed a hiss. Doesn’t seem to affect the tone. Anything you or other techs suggest would be appreciated.

They’re 60 years old, and liable to failure down the road, anyway. It seems like such a minimal expense, considering the overall expense of the amp restoration.

I have two in my possession that are original down to the tubes. One of them is the 17 off the line but I don't have the cabinet. The other one is a June baby and its a complete set. The cabinets came with a single 12 oxford speaker mounted on a projection ring. (Tone Ring) You talk about sound quality, Leo was on to something special there, to bad they got away from it.
