A good friend of mine was mixing monitors when the headphone amp in the Soundcraft he was using fried. Smoke poured out of the console, he wasn't sure what fried at the time. He quickly shut it down, and I had to come up with a couple of monitor mixes from FOH...

I once had the rectifier of an early 1960s amp self immolate during the recording of a guitar solo. The first 20 seconds or so, distortion increases, it gasps for air, the sound starts to get intermittent, and finally it just falls apart. A more or less perfectly timed operatic death. In a perfect world, it would have held out 15 seconds longer to outlast the fade. Please tell me this made the record. How could it not! It did. |

The Rectifier.
All's well.
That ends well.
Currently anyway.

Wow, an IBP is the last thing I would've worried about in the studio. That's wild. So glad everything is ok bgrotto ! |

Waves has been faithfully emulating this hardware behavior in their plug-in licensing model for many years. Almost indistinguishable from the real thing!

Something I’ve done for years with vintage amps that haven’t been used for a while is slowly bringing them up to power with the use of a variac to keep the old caps happy.

Something I’ve done for years with vintage amps that haven’t been used for a while is slowly bringing them up to power with the use of a variac to keep the old caps happy. Excellent idea. I do the same. I'll sometimes also use a lightbulb current limiter, which will indicate any short circuits present. I recently serviced a '76 Fender Super Reverb, which included a complete electrolytic recap. Working past when I should, I inadvertently tacked the positive lug of the very last cap to the wrong eyelet. Waited until the next day to fire it up. As I powered the amp up, a still, small voice told me to move my head back. Not two seconds later that cap blew...exploded...right where my face would have been. I saved that cap. It's on my workbench where I can always see it. A sobering reminder, that. Third man repair companion? |

Two questions:
Can caps vent while the device is turned off? The IBP was turned off, if I understood correctly?
Can this happen regardless of the age of the caps? the IBP looks pretty new.

Not likely, so probably depends on what "off" really means in the IBP circuit. It may have a "soft switch" which means as long as the power supply is powered on, so is the IBP unit - sort of. There are various terms for that (flea power, standby power, etc). A lot of devices do that, but that ultimately means the power supply -and filter caps - are "working" 100% of the time as well and caps have a life measured in power-on-hours. In the future, you may want to have a power strip (rack or floor) to turn it on/off? |

Yeah…..modern televisions and other appliances occasionally are of the “standby” mode rather than fully disconnected. You sometimes encounter stories of TV’s that were “off” that burned a house down.

A little labs IBP sits (er, sat) on the bolster of my console. I’m sitting there emailing this am, and suddenly I hear a loud hissing sound. Look down, and the ibp is SHOOTING smoke out of all its enclosure openings. I’ve never seen anything like ths…the smoke was like pressurized, firing out of the thing like someone lit a firecracker inside it. it was not in use, it’s plugged into a power conditioner (all the other gear on that conditioner is fine), just totally randomly caught fire. Wtf. so glad it happened when I was sitting there. I shudder to think what would have happened if it stayed plugged in unattended. ☠️ Damnit. Now I blame you for my amp and left monitor taking a shit. |
