Thanks for this video, i will have my Marantz 2226 this week and it needs a cleanup and new lights, and maybe it's good to mention that you're using two types of Deoxit, the D5 (red) for the switches, and the F5 (green) for the potmeters... 🍻
Replacing the vellum (which yellows with age) between the bulbs and faceplate will restore the signature blue color dial, when regular soft white bulbs are used. Not difficult to replace. That's what I did to my 2220. The tuning meter has vellum that can be replaced also, but a bit more difficult to do.
For sure -- I generally do warm white LEDs with new vellum these days for folks looking for the original look. Most of my buyers are going for the cool blue recently though and for that I tend to leave the yellowed vellum as it tones down the cyan just a bit. I've been working a while on a solution to the hot-spots the LEDs cause, but haven't come up with anything yet that really works and is also durable for transport. I have a 2230 that I hand-carved variable-thickness foam light filters and it looks absolutely perfect, but I'm sure the foam pieces would get knocked around in shipping, so it's not a viable solution at scale.
the "his" is due to defectives transistors. most likely in the ten times preamp . search the net of Troublesome transistors you will find a list along with the recommended replacements. motor boating sound is a bad electrolytic cap. time to replace all of them.
Depends on how clean you want it and how much risk you're willing to take. Some folks have had success with a low pressure hose. If you want to reduce risk, compressed air will get you halfway there, but never as clean as using water.
I've played around with various options and not seen a lot of difference. I usually do a quick wash at default temperature without soap unless the unit is full of nicotine buildup. For the really nasty ones, I go for longer cycles and/or soap. It's all about risk. Hotter, longer, soapier all increase the risk of water getting inside of components and destroying them.
@@cilynx thanks for your quick response. I have a Onkyo TX-2500 receiver which i bought on eBay and when it came, it was filthy and smell awful. I managed to get grime out of it but i still can’t get rid of the smell, and it gets worse when the unit is powered on.
Agree that the greening is caused by yellowing vellum, but what bulb you but behind it definitely makes a difference.

Awesome video. Really great detail on the Marantz. These look so much more organized than many of the other receivers out there.

Is there an alternative to the dishwasher ?

Would that blue be your choice if the receiver had a blackface?
I've yet to have one of the black faces on the bench to see in real life, but speculating, I think the royal blue might look really good with it.
How do you wash the unit in the dishwasher, did you use soap and hot water and for how long?.

The green/brown light has nothing to do with your bulbs. Replace the paper and nice blue returns.

@@cilynx To get rid of bright spots turn your LEDs backwards.
Did you remove the dial needle, lights and fuse before putting it in the dishwasher?.
