Hello Stuart. I can't ever remember seeing the can completely empty like that one. Still it's in keeping with the time of the year; fireworks night. Great video. take care Stuart.
Leo Fender would absolutely not give a shit. His original amps were made with poor quality off the shelf components that were barely fit for purpose at best and people have deluded themselves into thinking that shit like sag is awesome, actually, because THAT'S HOW LEO WANTED IT. OOH, NOISY FILTER CAPS ARE THE BEST! Don't you just love how LIGHT and AIRY those microphonic pickups are?!?? No, that's what Leo could get away with at a minimum to keep the prices of his gear reasonable, which was his only clear goal. That's fine. But let's not pretend like the dude was some bastion of quality. He was the Henry Ford of guitars and amps, not Steve Rollsroyce.
Great video! I had to fix ALL the pots on a fender fm212... Snapped off shafts.. what a nightmare pulling the pots, then reusing the "snap in" clampy deals that ground the pots and mount them to the flimsy pcb. Ended up flipping the snaps and putting generic pots in and just solding the snaps and cases of pots together. Worked well but was very very trying of my patience of a hobby/Amateur amp repair guy(this was my own amp, im not a hack taking people's money). Wish they could put more effort on these modern amps to make them last more than 15 years.
always love watching your videos it's like a nice jam being of a similar age I don't get many valve amp to Work on So I watch your videos the young seem to go for transistor amps😊 I work like you for the love of music and not the money
Looks like a double-sided board? Maybe. Which is a total suprise for fender cheapo boards. If not, I have seen people use the old cap's leads to j hook a new install. It's hard to tell on my phone, though. But that's my best guess
@@soapboxearth2 I suspect he did the latter. Nothing really wrong with that as long as you bend the leads to get a good mechanical connection before soldering. Beats the extra labor charges for the customer. Being a double sided board, if it's got plated through holes, it should be replaceable from the top as long as you can get the leads out without damaging the board. If they are bent over before soldering, that makes it more difficult and increased the possibility of damaging the board.
Ha ha! The Blown Capacitor Blues! Thanks again for another unique trip through a Fender reissue with poor design. I didn't know capacitors would do that. I guess it comes from age? Awesome job, Stuart.
@@MrStevehunter33 You mean like the garbage they were using back in the 50's? Whatever blew this cap would have taken out half the fuckin' amp if this were a tweed Bassman.
At 7:20, you selected the incorrect tube type: should have selected 6V6GTA, not 6V6. The original 6V6 was a *metal* tube with lower ratings than the "modern" 6V6GTA, and the 6V6G was a glass coke-bottle shape but with the same dissipation and max ratings as the metal 6V6. GTA, however, indicates Glass, Tubular, and uprated specs.
@goodun2974 of course. 2 watts dissipation difference. I just meant most people call all the 6v6 variants 6v6 without feeling the need to go into detail. I doubt Stuart is confused about it. He is just generalizing
I had a long discussion with some of my antique radio friends about shotgunning electrolytics in a 70+ year old device. Some of them say "don't fix it if it's not broke" but I say the caps are dead and there's a 50/50 chance they'll either giver poor performance or blow apart. Not worth the risk in my opinion, just replace them. And replace any IC capacitor on a modern device, they're less reliable than a Fan Shun Chinese made cap.
Yes there are two views and neither is obvioudsly correct. There's a cost involved in shptgunning all caps and for an amp that's played once a month in a bedroom, yiu could take the view that it's not worth doing.
@@stuartukguitarampguy5830 I will admit that it's a case by case basis, but the electrolytics should be replaced regardless if for nothing more that safety reasons. As for the rest, if I find 2 or more that are really bad, then it's a sure bet the rest of them aren't any better. Especially the ones that I call "crayons"- they are made of hard wax and have a thin paper wrap similar to a crayon. I've never seen a good one of those. I think they came originally with a 1 year guarantee. That being said, I've have found components in some German devices that tested strong at 60+ years old.
It never gets old listening to professionals whine about having to do their job. "They didn't build this so I could take it apart!" Yeah, no shit. They designed it to be built. This is why you're paid by the hour. You DO get paid by the hour and not by the job, right?

Yes I'm not sure I've seen one completely blown out like that!
Leo Fender would be turning in his grave if he saw the way they make amps today 😉😉
Sure would . Shameful. And people buy them up like hot cakes

Sounds like a mission. I hate those snap-in pots. Very hard to unsolder.
@stuartukguitarampguy5830 gotta love planned obsolescence!
Thank you Stuart, from Kansas, USA! Always look forward to your outstanding troubleshooting and resolutions.
Cheers!
Hey Stuart...Nice fix, explosive event..! Designed not for easy repair..! Great Job..Ed..uk..😊
Thanks Ed. It was firework night, after all!
Hi Steve,always interesting see you troubleshooting ,and i hope see the next video in short time.....
Cheers
Roby
Thanks Roby.

Yes I'm lucky hat I don't need the money these days so I can do it for other reasons.
I think the bad design is made on purpose. An human trait is to make life difficult for others... cheers matey good video as always.
I truly enjoy your program and I’m learning so much. Do you have a thanks button. $ ?
Always enjoy your videos, wish you had showed us how you replaced that cap from the top.

@@soapboxearth2 Hopefully he will see this and reply!

Awesome job, Stuart.
Not sure why it blew!
@@stuartukguitarampguy5830 could be that Fender using cheap shitty capacitors in their amps has something to do with it?
@@MrStevehunter33 You know what? I think you're on to something...
@@MrStevehunter33 You mean like the garbage they were using back in the 50's? Whatever blew this cap would have taken out half the fuckin' amp if this were a tweed Bassman.
Hope it was a faulty cap rather than an error in the circuit.
Yes I think it kust have been. I did this a year ago and it's been fine since.
My first thought was a cathode cap when I saw that, but I've never seen one blow before. Not very much voltage on them.
Yes not sure why it went!
@@stuartukguitarampguy5830properly dried out and then it became explosive. 😜

I'm sure he knows that. People refer to all 6v6 variants as 6v6.
@soapboxearth2 The specifications of the bias calculator are going to be different for a 6V6 versus a 6V6GTA.
@goodun2974 of course. 2 watts dissipation difference. I just meant most people call all the 6v6 variants 6v6 without feeling the need to go into detail. I doubt Stuart is confused about it. He is just generalizing

I come here just to hear Stuart butcher Ted Weber's name lol ruclips.net/user/results?search_query=ted+webber
Hey come on, I think I'm getting it right these days! Should be ashamed of myself because I was actually born in Germany!
