Do you receive decks to repair? How much would you charge for the repair you did for this RX-505?

Great to see that it is getting some love. Can you recommend a grease for all those plastic parts in the mechanism that will not dry up and leave a sticky goo? Plain white lithium grease or’’?
@hifirulezzz

Silicon non drying like Super Lube or Libra-film from Amazon

To me sticky lubricant screams one thing: WD40. I have next to no doubt Nakamichi didn't use a lubricant that dries up into a sticky goo. At this point I have 2 sets of oil and 2 sets of grease. Medium sawing machine mineral oil, thin silicone oil, Molykote EM-30L for plastic gears, lithium grease for metal. I have other lubricants and greases that I barely ever use. I've since started considering PTFE lubricant and graphite for parts that are sensitive to wet lubricants.

Hi, I own one in great shape, but it is original so probably in need of new belt, idler, grease. Do you do job like that ? Thanks

Hi, would you recomend to change traditional capasitors in playback amplifier (green 4.7nF in feadback path ) to polypropylene or polystyrene type? Will it improve THD, or all this is just audiophile endless dreems. I already swapped them to polystyrene but it will be nice to hear your mind Thanks

The schematic shows 10nF caps for C119/219. Not sure which caps you have in mind. I did not replace or measure those caps. The best THD is on my 680zx - 0.48%.

Please let me know if I can change the transport mechanism strap by simply removing the rear base or do I necessarily have to completely remove the transport mechanism? As shown at minute 15:10 it seems that is not necessary.

I am doing everything properly. Also, idler should be replaced as well and there is no way to do it not disassembling transport.

please help! my rx505 was working fine and I removed the top cover to lubricate the transport mechanism, sprayed some WD-40, activated rew and it worked fine but after that nothing works, the cassette does not move

Looks like you lubricated idler, make sure all rubber parts are dry.

@hifirulezzz OK thank you. I was just told to replay the record/play relay by couple of members on tape heads as its just a good maintenance idea due to the age of my RX-202. It's working great to my ears. I'm a beginner.

Wow! Thank you for the videos and the effort but I wouldn't let you come close to my gear. What a treatment you gave to the mechanism! Why didn't you take a big wrench and beat the crap of it till it surender the pinch rollers? And the head assembly - hanging on the head cables while you are wanking the mechanism all day around! Sorry for the word but sometimes when I see someone dealing with such a piece of equipment like a car mechanic it realy triggers me. Do you realize that there is no more production and those decks are growing rare? You should really let go the second dose of coffe and put the white gloves.

Well, I do what I know best. For example, I would never allow to heat those arms as their shafts are sitting in plastic. And many people recommend heating those arms. I am against it. And there is no easy way to pull out arms without using large grippy tools. So, I wish you luck with white gloves. I have fixed way more decks than many others. And these decks are working well till today. I have spare parts if needed - the privilege of buying decks for parts. You rather trust your mechanic or look for the one who you trust. There is no other way. Or better do it yourself.

Especially when it comes to such special models. I believe we would agree this one is unique in many ways. Thank you for making the video and please keep on. Cheers 🙂

You only did things by halves! I would have changed the two pressure rollers at the same time. They were worn out and will cause problems sooner or later.

I did everything needed for that deck. Used old Nakamichi rollers much better than new self-made ones. Don't tell me. I tried dozens of rollers and hundreds of decks.
