It's time for an update and some announcements on these legendary receivers. Need tools? Here's a video showing what I use (with links!): • Must-Have Tools For Wo...
I have head to wash out many a unit when using an air compressor just can't remove all the grime. (hey they have had 30+ years to build up dirt) Just always remember to use a compressor to blow out all the visible water while turning it over and over. Then use a hair dryer to help get rid of the water you can't see. Like under capacitors and tuning cans and keep going for as long as you can. Then let sit for at least a day or 2 before applying power. I also have a big box and UV lamp that produces ozone to first get rid of bad smells that many units sadly pick up from smokers etc.. I contemplated installing Bluetooth to older units, but the nice thing about these is that they are timeless. Once you install tech that gets upgraded every few years, you sort of put them into the same realm as AV receivers.
The best part of these vintage receivers and why we buy them is their FM Stereo tuners. Streaming is great, but there’s nothing like good local radio, properly reproduced through an analog tuner tuned with a graceful flywheel, and zeroed in with big meters. When you show us your work, please include the FM section (and if the tuning capacitor survived after power washing 😆). Cheers!
@@chublez Here in Detroit we still have WJR AM 760, a powerful clear channel station. In my younger days when we only could afford AM radio in the car - and those old Delco’s with a full throated 6”x9” speaker were awesome - I could drive all over the country and, at least after dark, hear such music programs as Night Flight, a 12 midnight to 5 am live adult music show hosted by Jay Roberts, Exploring Music, 12:45-2:00 pm CLASSICAL music hosted by Karl Hass, and Tiger baseball announced by the inimitable Baseball Hall of Fame member Ernie Harwell, all in glorious wide bandwidth AM, and, for a while, AM stereo. Now it is (well, was..) Rush Limbaugh and Dr. Laura 🥺. I used to love AM broadcast. I still have my McIntosh MR66 vacuum tube tuner that has an all-out AM section with 4 bandwidth settings including all out 15k extension. Merry Christmas!
Thinking that water and soup will destroy any electronics is just scared 😺 thinking. I wash everything I get. I will not work on dirty electronics. I been doing this for decades.
people don't seem to realize the PCBs are washed during production anyway - washing them later isn't a big deal. You just need to watch out for components that can hold water, or that originally had a protective cover on them initially when they were washed in production, like beepers and paper speakers.
For years I have been regularly repairing Quad and Martin-Logan electrostatic loudspeakers. Invariably, the panels all take a shower with me. Don’t tell the owners 😮!
Some decades ago Fender recommended removing all the boards from their professional mixers and soaking them in a Simple Green solution for several hours or overnight, rinsing them with distilled water and drying them for a couple of days before reinstalling. It worked!
For those into the finer points of home computers, they can get just as dirty inside, and there is a UA-cam channel by Cary Holzman, showing him power washing several computers, during the repair process.
Actually the correct way to wash that is one I use Dawn dish soap with just the hair little bit of bleach not just a spoonful disassemble anything that would be damaged buy moisture. I usually just power wash with a garden hose.
I don't install bluetooth boards internally any more. They can become out dated. For example, my bluetooth, with the 4.2, standard did not show up on my friend's new phone. Some companies don't bother to make their products backward compatible anymore (it did work with another board with the 5.0 standard). Looking forward to your future videos, thank you.
These will be fun restoration videos and educational as well as financial for you maybe. Will be looking forward to seeing the series and results. See ya soon.
I wonder if there is some sort of GPIO on the up2stream mini you can use to auto power on the marantz when content is playing. 5V relay across the power switch. That would be sick.
Good to see your follow up with the Marantz sr2030. Please tell me that the screws on the beautiful new face plate will be replaced with the proper bolts. Screws are criminal on any Marantz face plate. ;-)
I have an SX 750 sitting around that has a background hum. I haven't plugged it in for over 5 years, and my wife has asked what I'm going to do with it. I'm looking forward to watching you restoring yours, so I can judge whether or not I want to tackle the job, or trade/sell it. I found your channel when I clicked on a Jag LS swap video, and I stuck around for the HiFi gear.
@@b.powell3480 I replaced it with a late 80s Kenwood integrated amp, and my wife and kid like it better. It's simpler to operate. I'd like to get a nicer pair of studio monitors, so I'm still on the fence about the Pioneer.
I'm looking forward to hearing your thoughts on the power/speaker select switch on the SX-750. I own an SX-450 and an SX-434, and am wondering how much i need to be worried about their failing, and if there is anything that I could be doing for preventative maintenance.
People on Audiokarma have added a triac to switch the power on and off. this takes the heavy arc off the switch. Others have 3d printed the flat plastic disk that breaks and rebuilt the switch. If its stiff to operate the grease may have dried out and that in turn can break that plastic part. IMO
No problem with power washing but DON'T SOAK THE TRANSFORMER, can't stress this enough - there are paper insulators inside and the trafo might be ruined after some time.
One tip for everyone!, after power washing, use compressed air to dry everything off, and wipe off all damp surfaces to prevent corrosion!!
Blow dryer, set at medium. :-)

Pffft. AM better. Then again commercials suck.

I'm glad you're finally going to restore these vintage gems!
This is how I got introduced to your channel!
Going to follow. Thanks for putting your efforts out there.
❤
Fantastic job !!!

Nice to see your 2 rescues survived the punishment and you have some cool projects for the future
Power washing electronics is as old as the hills. The trick is to allow lots and lots of time for things to completely dry out. Ya dun good.
stick it in the hot press for a few weeks,,,

Ha, those are 2 that I use regularly
Love your channel

I love our little walks through the park.

Circuit boards are washed during manufacture. Powerwashing is fine as long as water is blown/dried off.
Amazing, how much the "chair" potatoes know, huh ! Looking forward to two adventures, thanks for update.
I look forward to the restorations.

I also submerge my dirty amp guts in my ultrasonic cleaner. They come out clean as a whistle. 😊
power washing freaked me the heck out

You should repair your receiver!, much better than the new ones!, you may only need to recap your unit ! Good luck 😊

I have a dozen old Pioneers from the 70s I found at thrift shops and thinking about sending them all to some yutuber and getting one back fixed lol.
@@genericsomethingGet a pair of Micca RB42s. Fabulous price and sound Ooh La La!
Very cool. Now I want to have a shower with my stack of various HK's!
If a Marantz 2270 can survive a house fire a little water can't hurt.
I've been washing & baking boards ever since seeing your video
Lmao again remembering you power washing those at the car wash.😄
Whatt was it that you installed to stream automatically to the Marantz receiver?

I don't like it at all. I would say if it's working, just go easy on it since as far as I know there's no easy solution to fixing them.

Blast it!
I would give you my two front teeth to restore my 2240!
Vindication! Old receivers encrusted with the soil of ancient Babylon? YOU get a power wash, and YOU get a power wash, and...
Dynamo HUM!
I soak my receivers in the tub to help loosen dirt.
A audio repair Tech should never use the phrase "There she blows". Just saying.
Power washing audio equipment is really not necessary, no matter how dirty the thing is.
I would Never do it.
