Just to be clear, this video is NOT promoting power washing as a method for cleaning your gear. It was my first time doing it and I took the risk because this is KZbin, and it happened to work out well in this instance. I had fun making this video and I hope you got some enjoyment from watching it!

[@patricknicolucci5073]

if its dried thoroughly it should be ok . Get it dry !

[@polarbear3427]

Why not? As long as the resistors don't fly around and the thing stays upright and not bangs on the floor; )

[@ThinkingBetter]

I just power washed my greenhouse plastic windows and realized the pressure was high enough to punch holes through it…but your pressure is more diffused so it is unlikely to cause actual damage. Electronics just need to be completely dry before power is applied and it’s ok.

[@Aswaguespack]

I am a ham radio operator and I remember back in the late 1970s one of our elderly local ham operators took his old Heathkit Receiver down to the car wash for cleaning then he put it in his oven on the lowest heat for a lengthy period of time (of course he removed all the tubes, knobs, and plastic for obvious reasons of course) and it worked fine after a thorough drying and spraying potentiometers with contact cleaner. It’s not something I would have done but with his experience he took precautions and it worked well for him.

[@fixerman3404]

I manufactured printed circuit assemblies for many years and they all went through an automated high pressure hot water wash to clean off the flux present in the solder. They were also conveyed through a heated air dryer section to make sure all the water evaporated. The key is to make sure they are fully dry which you accomplished nicely with your oven. I’m happy to see you didn’t fill it up with rice!

[@dixter1652]

not sure what equipment you had to wash the boards... we had a washer but it was filled with industrial alcohol... the top rim of the bath was a cooler so the alcohol wont evaporate... then of course it comes out into the air dryer.... the key if you use water is to use di water as its pure and has not metalic particles...

[@ozzyfranf]

Very bold move! I will now subscribe! Not to long I was at an auction & bought a 2015 receiver with the wood option. a 6300 turntable, the 5120 cassette deck & the Imperial 7 speakers and everything had the original owners "Handbook of Instructions" for the great price of $55.00. I couldn't believe it ! The door on the cassette is broke but everything works, the whole system probably could use a good cleaning, but I'm extremely happy to own it. I'm 61 yrs. so I remember when stereos like this we're popular.

[@Meridian83West]

Watching your video reminds me of an unforgettable Marantz print ad I saw in the 70's where the company got a letter from the owner of a 2230 whose apartment building caught on fire (a total loss, I think), and as he watched them clearing the debris a crane picked up what he thought was his 2230 receiver. He asked the crane operator to drop the load and it plunged to the ground. He retrieved the waterlogged receiver with its partially melted dial and destroyed power cord, let it dry out over several days, and replaced the power cord. He pugged it in, and the blue dial lit up. Its tuner worked, he checked all the inputs including the phono input and they all worked! Marantz checked his receiver and it still met factory specifications!! That's a testament to the craftsmanship the put into those 70's receivers!

[@michaelbauer6126]

Wow! I would have never thought to put a vintage receiver through a power wash at the car wash! But it looks like it survived. And not only would I like to see you rebuild and replace what is necessary and bring it back to spec, I’d be willing to take it off your hands when finished.

[@Giblet535]

That works sometimes. I did this with a 1942 Zenith radio before completely rebuilding it, but I used Purple Power and a brush. It works great now, at least as good as new. Replace every electrolytic in that receiver, check all the transistors, and it will outlast you. Electrolytics last 15 years according to their manufacturers. They turn into resistor/capacitor hybrids after that. Capacitors block DC. Bad capacitors don't. Replace them all.

[@DJBRENTAY]

Wrong

[@paulhovenga4138]

It's a cap coupled output amplifier. It will have DC riding until a load is present.

[@thisisyourcaptainspeaking2259]

I'd expect the output is dc coupled and previous stages are ac coupled. However, I would also anticipate dc on the outputs should cause the protect circuit to disconnect the speaker terminals.

[@debbieverret4033]

Not something I would attempt. You are one brave man.

[@k.givens788]

To date I brought a 2230 and a 2226B back from a similar state. I didn’t power wash mine. After having seen your video I would have. In any case, their restoration is quite fulfilling. Enjoy and have fun. Love your videos.

[@mdzacharias]

Normally with a cap coupled output, the DC at the speaker terminals disappears with a load connected. This is why the "bloop" sound when they first power up.

[@gino3286]

Hi i do not understand how with a cap coupled out we get DC The cap should not block DC ? can it be leaking ?

[@mdzacharias]

@@gino3286 You have to understand what happens as a cap charges up. Think of an arrow going in a counter clockwise direction from chassis ground up to the negative side of the coupling cap. This is the charge that accumulates when a positive voltage is applied to the positive side of the cap. It dissipates when a load is connected.

[@gino3286]

@@mdzacharias hi thank you for the very kind and valuable reply So the coupling cap has one terminal at half the supply voltage and the other to ground voltage continuously?

[@mdzacharias]

@@gino3286 Once the cap charges up through the speaker load, the voltage disappears. I don't think of it as "ground" voltage. That is where the speaker connection is made.

It's not cap coupled.

The pressure washing was hard enough to handle but I about cried when it tip over and smacked on the concrete

That was a lot cheaper than half a case of contact cleaner. Drying it in the oven was priceless.

[@vicv9503]

When CFC's were banned, The electronics industry moved to H2O as cleaner. i was just worried about the power transformer as the coils could still be wet inside. Heck i even wash my PC's motherboards with H2O and dish soap lol. the key is what you did, dry it. weather you use anhydrous alcohol to displace H2O, Infared(oven), or good old Sun. just make sure to dry it.

[@CotyRiddle]

I would not be to concerned about the TX as it is encased in metal and was not submerged. Sure water got in it but them things are heavily insulated and water should not get into it deep enough to really be of concern unless the insulation was bad to begin with. Still heating the thing up and thoroughly drying it is always the best thing to do.

[@TheLaw1]

I just stumbled onto your channel and it's an everyday mood for me. Liked the vid!

[@AL-tq9bz]

I still have my 1976 Marantz 2220b that I got for high school graduation. It has been in my parents house for years unused.. it originally came with the vinyl wood print covered metal cover.. I added the particle board walnut veneer case-- I left the vinyl cover metal cover on and just removed the feet and slid it inside--power cord first.. it still looks the same. I did clean it well a few years ago but it wasn't all that dusty being double vented--two case protection.. the 2220b only has one amplifer unit on the right side sharing both channels. I now just used it for the FM radio every now and then on Saturdays when I'm doing house work. It's a piece of fine furniture basically with the oiled Walnut case.. no scratches after all these years of basically sitting unused. I had used deoxit on the switches back when I dusted/vacuumed it out.. using a soft slim interior paint brush while using the vacuum.. I've replaced all the bulbs with the original fuse type, but that's really it. I don't use it enough for the bulbs to get all that hot. I'm planning to order some blue LED fuse type replacements, but for now it's not really necessary since I use my vintage Yamaha equipment if I play loud music. I remember a magazine article back when I first got the Marantz of a unit that had survived a house fire where the fire department had put out the fire and the Marantz receiver had survived falling through the ground floor during the fire suppression.. a little wet, some of the wood vinyl burnt off and power cord cut off from falling through the second story of the mentioned burned house fire.. I remember thinking how cool and robust this brand was to suvive all of that and fired right up after they replaced the power cord.. this in part was why I wanted one in the first place.. so I got mine as a result of the Stereo Review article.

[@jebeq2007]

A lot of people have no idea that you can wash your electronics. I have done this with my vintage analog synthesizers and it always worked great. Only thing I would say is spray some Simple Green and let it set for 5 min then power wash it to dissolve the difficult dirt. This method worked great.

Those aren't "upgrades". That is called "molestation", and reduces the value of the gear.

Thanks! I'm surprised as well about the pressure. On the oven temp, it was simply the lowest the oven went.

All of the components would be probably be able to survive boiling water, so anything under 210F would likely be fine. But going with the lowest possible temp is certainly the safest choice!

[@foobarmaximus3506]

That was as low as it would go. You didn't watch the video?

[@williamnaman3570]

I just want to say what I would do to clean this in a low risk way. If this is discrete component electronics, test the unit, discharge the caps, turn the unit upside down and use a multi straw vacuum head to clean out the heavy dust and dislodge it so it falls out. Use tuner cleaner on all the pots. Spray all the vacuumed spots with 90% alcohol and let soak but not dry. Then rinse with more 90% isopropyl being careful not to get it on the pots or plastic components of the face. If soaked, some plastic components will fracture from alcohol. Let dry in the sun.

I have done the same thing on old gear. My friend brought me a Pioneer SX-950 that was in a fire and fell through the floor and into the basement, when the fire department came and put out the fire the reciever sat under water for several days. I let it dry out and I hard wired a power cord and speakers and it came on and the relay clicked and it worked fine. I had to replace all of the jackes and knobs, I used it for about a year until I sold it to my friend and I think he still has it. After that I power wash alot of equipment and let them dry out in the Florida sun. Call me crazy but it works for me.

[@curtchase3730]

LOL wow, same here! Very similar deal. A friend had some late 80's Sansui equipment went through a fire and dousing by dirty water and was under water in the basement. He gave me the stuff and I "washed" and blew out w/air, let dry for a week and it all came back to life! Like your stuff, due to the heat melting knobs and stuff, we tossed it out anyway. Shame

[@MiguelDeMarchena]

Dust has a lot of salts and metal particles and with enough air humidity it can become as conductive as a wire producing shorts, if your circuitry do not have any part that can result damaged by washing it with water then why not give a try, great job. My suggestion is to replace all the potentiometers and switches that generate noise when turning or pushing and refresh all soldering with fresh thin using neutral pine flux, thank you for the video.

[@ericbentley8519]

Never thought about the power washing process, but working in electronics industry yes we wash water soluable fluxes. We usually use DI/RO water and will meter in an aqueous batch cleaner. Other than you would be shunned by other members of the household, good dishwasher with aqueous batch cleaner in the rinse aid bin works too!

I worked in a shop many years ago that rebuilt mining pumps, 3000 + horsepower and about the size of your Volvo. These things would come out of a mine and they were FILTHY. The control boards inside enclosures looked as dirty as that receiver. All of the electronic PC control boards were carefully removed, washed by hand under a shower head in a sink with a soft brush and degreaser, blown with low pressure compressed air, placed into a dish rack, and then into a small tent with a dehumidifier and a fan blowing on them for 48 hours. No problems whatsoever and the boards looked like new, far easier to test and replace components on for the techs also.

I washed many TV and Radio chassis in the sink or dishwasher but never used a power washer. I used a hair dryer to knock off most of the water and then placed a small table fan next to it for hours, making sure to 100% dry everything before attempting to power it up. I also recommend spraying DeoxIT or WD40 inside potentiometers and other tiny places which might have trapped the water.

[@foobarmaximus3506]

I like to use a heat gun at a safe distance, but yes - same effect. You are correct, and it does work. I think he proved that here. I'd hate to let water get into the main power transformer, but they are usually sealed pretty well - and if dried quickly, they be fine.

New sub here. Between the humour, the cool old Volvo & cool old electronics the channel really ought to take off well. Key to washing electronics is (as already stated loads of times) to make sure it's 100% dry before applying power, and ideally before weeks pass... Main thing that worries me about pressure washing is driving moisture into bigger transformers &/or damaging smaller transformers/coils. Other than that, hosing off is a reasonable way of cleaning grime off & in extreme circumstances (lots of cat piss) I've even thrown them in the dishwasher.

[@EnzoFerenczyo]

That's what we do in the factory, brand-new PC boards of all types are put in a "dishwasher" made with slots for the boards.

[@pauliedweasel]

We actually used to wash really dirty test equipment at Hewlett-Packard. We used a compressed air wand that sprayed water and soap solution on the equipment followed by a fresh water hose down and finally we used compressed air to get most of the moisture off followed by a three to four day stay in our hot air oven with blowers circulating the hot air around the equipment. The only casualties was that sometimes the transformers on the older tube type equipment would give out because of incomplete drying, even after seven or eight days, necessitating replacement of the transformer.

Love this channel. How did you get your knowledge of electronics? School? Thx

Basic theory in high school and college physics, but all applied knowledge through being self taught, reading the forums, and having a good mentor along the way.

I've cooked motherboards in the oven to revive them. Just because someone said it can be done!! It worked.

I had done this kind of washing on colour tv, amplifiers, computers and electric fans with bathroom hose. Just cannot bear to see all the dust on the equipment. Simply leave it to dry out for a week and you are ready to go. No need to go through all the above processes.

Are the bench speakers KLH Seventeens or from a KLH Model 20? Liked the power washing BTW. Always wondered if that would work. Guess it does. Glad to be subscribed.

What a great wife you have allowing you putting that thing in the oven. Take care both of you. Life is good.
