JVC - tougher than the rest
If you read amplifier reviews in hi-fi magazines you will find lots of irrelevant guff about 'musicality' and 'inky black silences'. None of this really matters, the key parameter is 'does it still work after you've put it in a bath of water?'.
This 70s JVC does (see picture, all but a little bit of the back is under the waterline), it ponged of wee and this was the only was to make it usable in a domestic setting again. A good soak, a few hours by the heater and it was as good as gold again, just minus the smell. Made in Japan: Sign of Quality. Last edited by Studio263; 14th Oct 2019 at 11:31 am. |

Re: JVC - tougher than the rest
I hope you dried out that 13A mains plug too!

Re: JVC - tougher than the rest
I sometimes add a little detergent, and maybe rinse with de-ionised water or propan-2-ol if it's something fussy. The water here is rather hard so it does stain a little.
I expect the sound will just wash over you now Or maybe it will sound a little to clean ? dc |

Re: JVC - tougher than the rest
That looks like it has suffered the "common domestic cat" problem.

Re: JVC - tougher than the rest
In the early 80s I bought a Philips 1700 that someone had spilt coffee into. One PCB was covered in the dried brown goo and a resistor had burnt out, quite possibly as a result of the coffee. I tried all manner of solvents with luck, then I soaked the board in warm/hot water. Hey presto the coffee dissolved, leaving a perfectly clean board that I simply dried off overnight. I replaced the burnt out resistor and the set worked fine!

Re: JVC - tougher than the rest
I hope that's de-ionised audiophile water you used...

Re: JVC - tougher than the rest
Its actually drawn from the lake of tears of all of those who bought Leak, Quad, A&R, Cyrus, Cambridge etc, and then realised that they break down a lot more than the Japanese stuff does with no real world performance advantage.

Re: JVC - tougher than the rest
Amplifier successfully de-ponged, but the bath now smells a bit...?

Re: JVC - tougher than the rest
I've washed countless PCB's over the years, many of them main TV chassis.
Here is an RC getting the treatment with washup liquid and a soft brush. It comes up absolutely as good as new. (I would make sure the mains tranny is fully dry and that could take many many hours) |

Re: JVC - tougher than the rest
I don't see any Radox [or scented candles] ..... sooooo don't expect any 'relaxing mood music' out of that particular rig!

Re: JVC - tougher than the rest
Hope you put your little chap in for his bath at the same time. Don't like to think of all that water going to waste.
Wait a minute... just looked out of the window at all the 6" deep puddles |

Re: JVC - tougher than the rest
I've heard of someone on here once using a pressure washer on vintage TV chassis before, and they worked fine afterwards! I have personally chucked a complete CD player into an ultrasonic cleaner before, laser included, and it came out working just fine after drying it out for a few days.

Re: JVC - tougher than the rest
Reminds me of the old days when PC keyboards were rather more-expensive, and dunking in the sink was the standard treatment when someone spilled coke/beer/coffee/tea/hot-chocolate/milk into one.
(In later years when you could get an new keyboard for a tenner we just issued a new keyboard rather than spending time trying to clean-up those which got gunged). |

Re: JVC - tougher than the rest
No need here, like a lot of Japanese equipment this unit is full tropicalised, including resin impregnation for the mains transformer. It is designed to be reliable, even in humid climates.

Re: JVC - tougher than the rest
Actually it was the water that he'd had his bath in first. He's quite used to there being parts of TV sets and audio gear in the queue after him, but never a complete unit. He did ask about that...
