Vintage Yamaha R-300 issues

I am currently using my Dad?s old Yamaha R-300 stereo receiver (I thought he had a CR-240 but I just noticed thats not what this is lol) at work to drive my headphones using my iPhone. Firstly, GOOD LORD this thing sounds good on just headphones! I know its VERY good at driving speakers I haven?t EVER got this much bass response in these headphones even without jacking up the bass on the AVR (but I tweak it anyway ). Considering how crappy my headphones are, I cant wait till I get some better ones.
I have a couple issues with it I am thinking I know the answers but wanted to poll the forum. My iPhone is currently connected via a 3.5mm to RCA adaptor (cheap Monoprice one). The Yamaha uses a bigger jack than just 3.5 (forget what size). I am currently using an adapter from another set cheap set of work headphones to make it work.
It works ok, but when the balance knob is on 0 there is a TON of static in the left channel and I get no sound out of that channel on the headphones. A slight twist to one side or the other gives me full volume with no issues.
My initial thought is to just go buy some de-oxit and spray it into the balance knob, and all the other knobs as well as the inputs on the back of the unit. Assuming the static is still there at that point, anyone have any suggestions?

Also need to find the bulb for the tuner section as its out. I still get green when it locks in on a station, but I believe there was a light for the number section so you can see what the range your in is. See pic below:
As this is my dad's old AVR and I have lots of memory's with this I would like to go ahead and replace it to keep it exactly as it looked when it rolled off the factory line.
I believe in the picture on the link below is is what its supposed to look like:

Doesn't sound like anything is wrong there that De-Oxit won't fix. With the lid off of course.

with power off you can try to remove knobs from front and spray some deoxit and work back and forth 5 or 20 times and after giving it time to evaporate you can power up and recheck. Most like though you will need to remove the case cover and look for where the knob shafts go into the receiver and spray from the back side as well.2-ch System: Parasound P/LD 2000 pre, Parasound HCA-1000 amp, Parasound T/DQ Tuner, Phase Technology PC-100 Tower speakers, Technics SL-1600 Turntable, Denon 2910 SACD/CD player, Peachtree DAC iT and X1asynchorus USB converter, HSU VTF-3 subwoofer. -
Dan- also check out AK forums for more detailed threads reguarding fixing the lighting issue. I've found some good info there on my CR640 and lamp replacement is a common issue with lots of good topics providing sources for bulbs and how to do it yourself.2-ch System: Parasound P/LD 2000 pre, Parasound HCA-1000 amp, Parasound T/DQ Tuner, Phase Technology PC-100 Tower speakers, Technics SL-1600 Turntable, Denon 2910 SACD/CD player, Peachtree DAC iT and X1asynchorus USB converter, HSU VTF-3 subwoofer.

Deoxit should do it.
And also, get one of these: It sounds better.

Gracias! Will give this a try this weekend. I have to say I am really enjoying this small office rig (not techincally small though lol). As it was my Dad's its got LOADS of sentimental value to it so I am glad I will hopefully be able to keep it going strong.
P.S. he is more ANAL than I am about storing stuff lol. This thing was inside 3 different garbage bags tied shut to keep it from getting dust or water on it :biggrin: This thing looks looks almost new (couple dings but whatever). I will give it a good cleaning Sunday.Dan- also check out AK forums for more detailed threads reguarding fixing the lighting issue.

Yeah, been over there looking at bit myself, found some possible helpful info.
I am debating buying a LOD to RCA cable for my iPhone to hook this all up. I am torn however as I also have a portable headphone amp thats hopefully showing up soon and I dont really want to get 2 LOD cables (they dont take the same one :sad).
I think I might just listen to both for a bit and after hearing which is better stock get a better cable for that setup to start with..."....not everything that can be counted counts, and not everything that counts can be counted."

Joe already one step ahead of ya
Looking at either one of these (for the yamaha):

Or one of these (for the headphone amp):

Congrats, nice little Yammie there, just after the CR series so still pretty good quality. As mentioned, DeoxIt is your friend. Which reminds me, I have an HK 430 and a Technics SA-5570 that need a little attention there!
The Technics also has to be cleaned out because it looks like the underside of one's bed after a year of dust bunnies have collected under there, or in this case, IN there.
Have fun!

^Yup, planning on messing with this on Sunday while my wife is at work. Until then I will just keep on enjoying it at my desk :biggrin:"....not everything that can be counted counts, and not everything that counts can be counted."

Ender, glad to hear your ordering a different hook up. Your ears will thank you.
I have done the old 3.5 to RCA route and the Ipod to RCA is just a thousand times better.
When you use the Deoxit, make sure you are in a well vented room or garage. That stuff can get you so HIGH.
And really give it time to dry. It is pretty instant but be careful. -

Yup, really wish that PEPSTER made LOD cables so I could keep it in the family but he isnt there..... yet .
For just casual listening at work (with one headphone ear off anyway) it sounds pretty darned good.
After I spray it with de-oxit I will be leaving it to dry overnight so I should be good."....not everything that can be counted counts, and not everything that counts can be counted." William Bruce Cameron, Informal Sociology: A Casual Introduction to Sociological Thinking (1963) -

Most like though you will need to remove the case cover and look for where the knob shafts go into the receiver and spray from the back side as well.
Leave the front knobs where they are, spraying anything from the front end is a waste of product. Remove the lid. Look straight down on the Balance knob and find where the shaft comes through the other side. Enclosing the shaft is probably a round type metal housing with a round opening on top, and maybe the sides too. Spray the De-Oxit in those openings and then work the controls back and forth a few times or a hundred. I spray them again after I'm finished working them, but that's just me. Flush all the junk I just worked off away maybe. Do that for every knob and switch on the front panel. Especially Tape Mon switches, Speaker On/Off switches. -

Do I do the same for the connections on the rear or no?"....not everything that can be counted counts, and not everything that counts can be counted." William Bruce Cameron, Informal Sociology: A Casual Introduction to Sociological Thinking (1963) -
You can spray some on the outside of the female RCA inputs on the back but I wouldn't go ape-**** back there. It's those things under the hood that give the trouble.
The trouble spots/contacts may be exposed and not in a round type metal housing. If that is the case, you can easily see what the results are when you spin those knobs and look straight down. You can actually see the electrical contacts that you are mechanically moving back and forth and you can spray that stuff onto them much more easily. -

Cool. I might just use compressed air back there just so its all cleaned up"....not everything that can be counted counts, and not everything that counts can be counted." William Bruce Cameron, Informal Sociology: A Casual Introduction to Sociological Thinking (1963) -
George is way more knowledgable on this than me Dan. I learned later on to be effective to remove cover and do as he stated. I still do the front for my own peace of mind and probably am wasting the deoxit. On the back air, can remove some, but I spray deoxit on a toothbrush and scrub the rca a little to remove any grime that has accumulated.2-ch System: Parasound P/LD 2000 pre, Parasound HCA-1000 amp, Parasound T/DQ Tuner, Phase Technology PC-100 Tower speakers, Technics SL-1600 Turntable, Denon 2910 SACD/CD player, Peachtree DAC iT and X1asynchorus USB converter, HSU VTF-3 subwoofer.

Hmmm... He could be going for that effect, I can picture ES now in his increadables costume, in a closet, deoxiting all of his components come Sunday!! :cheesygrin: -

Here's a tip I picked up from someone concerning cleaning the RCA ins and outs on the back. After you clean the outside rims with deoxit, take a Q-tip, rip most of the cotton off it and spray it with deox, then use the end to gently clean the inside of the RCA out--it just about fits, probably a little loosely so you can twirl it and run it around the cylindrical interior working it in and out of the opening--I'm really not trying to be "graphic" here but it's kind of hard to escape it. lol. This "really" helped the connections on my Onkyo P-304!

Haven't gotten around to cleaning the unit, but found if I use the Mono mode on it I dont get any static with my headphones. Works for now, but still plan on some deoxit maybe this upcoming weekend...."....not everything that can be counted counts, and not everything that counts can be counted."
