Marantz 5000 1970s Cassette Deck - Belts, Light Service & Calibration

[@he110itsme]

I really enjoyed watching that as it reminded me of myself all through the 90's, when I had my own electronic repair business. I still do repairs but I've changed employment since then.

The reason the dolby symbols are at +2 vu is if you calibrate the machine using a dolby level test cassette at 200nWb/m (ansi)the meters should read on the dolby mark, not 0vu. 0vu is 160nWb/m.(din) on these old machines. The meters should only be calibrated in record mode injecting a signal into the machine at 1khz and monitor the output at the test points to correspond to the manual. If the meters are off at the correct level then you adjust the meters then. This is explained in the manual. If you calibrate at dolby level +2 then you multiply the level in the manual at 0vu by 1.3625 to give the level at dolby. ie if the manual suggests 480mv out at 0vu you multiply 480x1.3625 to give you 654mv at the dolby level. Machines that don't have the dolby mark on the meters (Nakamichi) are dolby level at 0vu 200nWb/m. If tapes made on a nak are played in the Marantz they should be hitting the dolby mark.

I love the smell of capacitors in the morning too. Unless they have started leaking, of course.

[@pwrestoration]

Electric celery! It smells like a newly opened packet of postits. Or even a new spindle of blank CDs

Thanks for reworking the audio on the video. - Very informantive thanks

[@pwrestoration]

Ha no, thanks for letting me know - it all seemed good this end. Turned out I had a copyright claim which seemed to have messed up the audio. Hoping I can get a way to demo repairs and yet use uncooyeighted music. Time will tell, it's one thing after another 😅

[@ju6452]

❤Got one 5000, too. Lovely, good sounding machine😊.

[@les4lb]

Thank you very much, I have the same issue with a 5030!

[@AudioElectronicsChicago]

Beautiful deck

[@BKing460]

Fantastic video!!!! Thank you very much!! :) I managed to completely repair the Marantz deck!

[@AlistairAnderson-q1w]

Great really enjoyed watching, I bought this marantz 5000 tape deck back in the mid 70s from new still have it and it works, I've spent a dit of time changing belts and cleaning the record switch mechanism over that time, only problem is I think it's running a bit slow but I don't have any of those scopes, so do you recommend adjustment by ear.

[@pwrestoration]

Yep ear is as close as you'll get it without a calibration tape. You can use an app called spectroid if you buy a speed calibration tape, theyre usually about £10.

[@hermanmunster3358]

That is a gorgeous looking deck, and the music near the end sounds great. Not trying to tell you how to suck eggs, but when calibrating the VU output, wouldn't it be easier to record a 3000hz test tone at 0 dB, then you would have a nice steady tone to work with when adjusting the pots?

[@pwrestoration]

You're absolutely right, I think on the day I only had the one deck handy though so was a bit stuck 😄

[@stuartsiddall3515]

Great video! Have you a link to the belts please as the link has expired. Cheers.

[@pwrestoration]

Hi sorry I don't

[@mitchflanagan8901]

Great video. I’ve got one of these on the way. Can I ask what pinch roller you used ? having trouble hunting one down

[@pwrestoration]

I ended up measuring the old one and ordering a generic replacement. I can't remember what size it was but they're listed by outside diameter / width / axle diameter. For example 13x11x2mm. Good luck! They're available on fixyouraudio.com

[@jamesshackelford3702]

She's gorgeous 😍

[@Stephen.C.]

If you were setting azimuth, for 0db vu meter position, with the test tape, and they didnt match, how do you know its the meters that need adjusting and not the output pot. on the board for that channel? Enjoy your videos by the way.👍

[@pwrestoration]

I can't remember the specifics for this one but generally I get them to match by azimuth and then adjust the playback pots by oscilloscope later. Usually in a service manual azimuth is the first thing to check

[@theaylesburycyclist8756]

Thanks for making these videos, I really enjoy them. Can I ask what spectrum analyser app you're using, please?

[@pwrestoration]

Sure can it's called Spectroid Android play.google.com/store/apps/details?id=org.intoorbit.spectrum It doesn't appear to be on the Apple store.

[@joewoodford9428]

Could you tell me the belt lengths, I have a Marantz CD-314 which uses the same main deck and looking to get hold of belts to replace main drive, ff/rewind and tape counter.

[@pwrestoration]

Not sure on lengths but you can get the kits off eBay www.ebay.co.uk/itm/334506785244?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=_7R0RU3ES0G&sssrc=2349624&ssuid=qI2jvYkCTXO&var=&widget_ver=artemis&media=COPY

Don't understand your mumbling but your music is loud.

[@pwrestoration]

Cool story Darren thanks!

[@zs1dfr]

I really enjoy your videos. But for someone who is not used to your accent, you really need not to mumble into your beard. You need a better microphone. Sorry for picking nits, but I watched and didn't listen because I couldn't understand what you were saying half the time...

[@pwrestoration]

I totally agree I just wish I could grow a beard! I've been working on it. It's difficult when it's my accent, but hopefully if you have a look at a more recent video, I've got better. But I'll always take constructive criticism! 😀

[@zs1dfr]

@@pwrestoration Thank you for answering. Yes, you have got it better. The extreme difference between your voice audio and the "musical" interludes exaggerated your inaudibility. Thank you for being receptive. I am a radio ham, so appreciate good voice audio, and strive for it myself. Have a happy weekend and thanks again

[@pwrestoration]

@@zs1dfr @zs1dfr well you're 5/9+ this end, all the best 73 - M7PNB 😊

[@zs1dfr]

@@pwrestoration And you are too, M7 Please No Beard! Happy weekend to you. Your electronic skills know no bounds, and are enjoyable to learn from.

[@marcusharmon8389]

I was waiting the whole time to hear it and wasted my time !!!!

[@pwrestoration]

Yeah I've taken that tip on as my channel has progressed. I've now got a tape of royalty free music I like to use, it's part of my channel journey!

[@pwrestoration]

All part of my channels journey, a few people have said that. Now I have some KZbin royalty free music I use to demo. Every day's a school day!

[@sergiototote]

Hola!!! Tengo un modesto pero lindo cassette deck marantz… sd800, perfectamente conservado, nunca se le ha hecho nada de servicio , y todavía funciona perfectamente… claro que necesita mantenimiento y retocar su cubierta de madera… pero está perfiecto… quise venderlo paro me di cuenta que está muy barato a la venta y mejor me quedé con el… pero si me gustaría que alguien con conocimientos y herramientas como en tu caso le diera el servicio que necesita para su preservación … Felicidades y saludos a todos…🎚️😀
