as 36y member of the audio engineering society & somebody who never drops comments… your videos are spectacular. Spectacular. The next time i have a problem child? I’ll be contacting you. Job well done & very edu-taining. 🔮
I've had to deal with some pretty 'derp' roadies in my 35+ years of live work, but I've never run across any who would do that. That being said, there's always got to be THAT one somewhere in the universe who means well and tries his hardest to get the job done. And that is where the blame lies fully on Bogner letting that amp go out the factory door with that fuse marking. A few more cents in ink, or a lack of it and a more concise printing for destination country power, would save a whole lot of B.S. all around. Shame on you, Bogner. Thanks for bringing this to everyone's attention, P.A.
Both are at fault. 30A is probably a lot more than the power cable can take and more than most building wires can carry. If a thing actually has a 30A mains fuse, it would be wired like an industrial oven or an EV fast charger or something. Having a mains fuse that's TEN TIMES bigger than any other piece of electronics a even a roadie sees should ring some bells.
I love Reinhold Bogner...but god damn that's crazy. I'd also fire that Guitar/Amp Tech if I were that touring musician. You need someone with a bit of brains to make sure your amps don't die or murder anyone.
First immediate reaction: That's insane! Perhaps later there was change that I haven't seen yet, but it seems to me putting black marker over the 2 isn't permanent enough. The marker could wear off again. Is there a reason why painting over the 2 with some brush on Testors green or black enamel model paint or colored nail polish wouldn't be better? Just saying/asking.
// That the road crew didn't realize that 32A couldn't make sense is comically sad. I about consider myself to be a moron with regard to all things electrical and electronics but even I know 32A makes no sense. I mean I know the breaker for the central air at my house is 30 amps! My home level 2 EV charger is 40 amps on a dedicated 50A breaker and circuit. Yikes.
As a Bogner Goldfinger owner and having looked inside the amp I can say that it is high quality but not made to be easy to repair with multiple tiers of PCBs due to the amp's switching complexity. Getting into the front panel pots would require a lot of disassembly. Best sounding amp I have ever owned tho! This Shiva looks a lot easier to work on at least but that fuse thing is definitely rubbish. It would not cost them any more to print "120V 3A, 230V 2A" on it. That said, some of it is on the roadcrew who could have just downloaded the manual on their phone and double checked by the time they figured out they could not find a 32A fuse.
I could almost understand if a roadie thought it was a 3.2 amp fuse, with a dot between the numbers having faded away, because a 3.2 amp fuse does exist and would be both more reasonable for amplifier protection, and easier to find, than a 32 amp fuse. Anyway, aren't roadies or on- the-road guitar/amp techs supposed to carry fuses with them?
Well technically a 32 amp fuse would be a "Slow Blow" if at all. Good thing the magic smoke didn't escape from the transformer or other expensive bits.
OMG My own Bogner Shiva is shaking in it's boots.. "Don't let me near that road crew!!!!" and indeed, after looking at the back of mine.. it's got the blacked-out 2, as plain as day. What kind of crap idea was that Bogner?
Convenience outlet circuits (the kind we plug amps into) are only rated for the largest outlet rating, so 15 or 20 Amps in the USA? How does 32 Amps remotely make any sense? It's a guitar amp, not an arc welder!
WOW! That is fucking crazy. Thank the heavens the amp wasnt damaged worse. But I think he needs a new "Roadie/Guitar tech" hehe. I had to send this video to my dad just so he could see this. :-)
I had a Mesa once where the roadie stepped over the speaker cable and it got unplugged while the amp was fully cranked. The plate voltage got so high that it arked into the heater connection and evaporated the clamps in the socket and the pins of the tube completely. New Socket and new tube in and it luckily ran fine but this could have ended badly. Thats why i like to install overvoltage protection across the output transformer as it costs next to nothing. But this markings on the Bogner are exceptionally stupid!
Did they plug into a higher voltage supply? How do you do that when the plug ends are different ? Just wondering. If it was plugged into 120 VAC then something else was wrong....but how do you plug into a 240 V circuit? Special dummy adapters? Or dummy special adaptors?
Likely just grabbed a different lead with the same IEC C13 plug on the amp end, and the appropriate (...or highly inappropriate, in this case!) plug at the other end. Hell, they probably have a big pile of 'em, and plenty of other equipment that works on both voltages; so just did what seemed to make sense and plugged it right in.
@@tamberp You're right that could easily happen in the modern world. I was picturing a power cord connection like a Fender amp from the 70's would have.
Road crews should have copies of the manuals. Or get their fuses from an amp tech. Where I live, there are a lot of music festivals and road crew folks come into my shop and buy fuses. I always ask and make sure they get the right ones. I buy from amp suppliers, so I wouldn't have anything that high.
ha ha,,, 230V AC (Europe) times 30 amps is around 7000W,,, ha ha ,,, somebody flunked basic electricity one on one.. that is 117 60W lightbulbs on at once.
I would be having a serious "Come to Jesus meeting." with my road crew. (A) Most USA 120 Volt outlets are only rated for 15 or 20 Amps, (6-13 Amps for European 230 Volt 50Hz). It's not an arc welder, a compressor, a 40 gallon water heater, a clothes dryer or an electric oven, so??! (B) How many guitar amps have actually had more than a 5 amp fuse? Even the mighty Ampeg SVT only used a 10 Amp fuse. The Sound City Tour 120 or HiWatt DR203s are about the only guitar amps I can think of that used 5 Amp fuses. Most 100 Watt amps used 4 Watt fuses. (C) Please, read the total power draw on the back of the amp! Divide the Watts by the Volts. Does a 32 Amp fuse remotely make any sense at all? NO!
I like to use one of these inside the amp and load it with a slightly larger fuse. I kinda idiot proofs poor fuse choices. www.ebay.com/itm/122775005268?
It is in fact the same 16a or 20 amps in Europe. Consumer electrical circuits for sockets are 2.5mm2 copper wire and it is rated for 20A, but overcurrent protection of 16A - just like most of the sockets. If You were to use (for any wicked reason) the same construction of US socket for 230v you would rate it for the same current, only check the maximum voltage - which is the strength of the isolation. It is the same heat produced in socket with 16A120v like 16A230v.
I understand this is 100 PERCENT the fault of Bogner, but........what kind of "road crew" for a touring musician would ever think a guitar amp would have a 32 AMP FUSE. Come On..... for F-Sake..!!!
