I was told that i can post this here Anyway the story is, I accidentally dug this thing out of our family storage. No idea it ever existed, my dad told me it was a gift from a friend aeons ago. My question is, is this thing any good? or is it anything special? would like to learn more about it! Thanks!

If it works well, it is clearly a keeper. Maybe even if it doesn't and can be reasonably brought back to life. See:

Oh ya forgot to mention. It works like a charm. Just hooked it up to a pair of late 80s Aiwa Speakers.

Welcome to the vintage club. Glad to have you aboard!

Beautiful vintage amp. Congratulations and enjoy.

For the Phono stage alone its probably worth more than it would cost to tune it up. Vintage Marantz stuff tends to be well regarded and reasonable to sell.

Snagged myself a winter project, its in Urmm original condition but does works and I'm thinking of a rewire.
With the signal wires coming with bare wire ends and someone cut the ground wire off, the power wire looks its age.
I want to keep the plinth vintage with wood sides and leather trim, so a clean and refinish on the wood.
The cart is a Shure M44e I'll leave that till the other works done.

Very nice @northendjazz. Enjoy!

oh ya about that. i have a question, i wasnt able to test the phono stage properly because i have no idea how to hook up the phono stage ground from the marantz. my turntable is a at-lp60 that does not have a ground lead.

^ The more critical question is: does your budget TT have a built in phono stage--and if so, can you turn it off? The phono input is designed to be used only for TT's without that feature. If you have and are using an internal phono pre-amp, then you need to connect your TT to the Aux input instead.

With regard of your original concern, some TT's, especially budget models, do not have a ground wire. In such cases there is nothing to connect to the grounding screw on the amp or receiver.

yes it does have a built in phono stage and yes it can be bypassed with a switch. hmm i guess there's no way to test out the phono stage of the marantz as of now unless i upgrade my turntable. what can i expect if i change to a better phono amp? eg if i ever get a chance to run the marantz, better sound quality? is it possible to get like a 3 prong uk plug grounding cable and connect it to the phono amp. will that work?

 

[KG Jag]

Make sure you bypass the internal phono pre-amp (usually by selecting "line" or "off"). Next plug it into the phono input of your amp (rca terminated). Start your test with volume at or near zero. Your TT is internally grounded--for better or worse.

A properly working Marantz internal phono pre-amp is very good. Your current TT and cartridge--not so much. You need a good quality TT and cartridge to get an idea of how good the Marantz phono pre-amp is.

 

[Van Isle]

No, if you bypass the built-in phono stage in the turntable, then the output has to be connected to the phono-in of the Marantz.

Remember, that a phono pre-amp does two things:

1. takes the very low-level output from the cartridge and boosts it to essentially the same level as one has for the AUX/CD/Tape inputs (i.e. to 'Line Level').
2. takes the signal as recorded on the record and applies a equalization curve to that signal. The signal on the record has low frequencies reduced and the high frequencies boosted, (see here: https://en.wikipedia.org/wiki/RIAA_equalization).

So if you plug the by-passed turntable output into a line-level input, your record will sound like faint, bass-shy 'Alvin and the Chipmunks'. Plug the non-bypassed output from the turntable into the phono input and you over-drive the pre-amp in the Marantz, potentially doing damage.

i guess its time to get a decent vintage tt from the used market. even though i just got the audio technica like a week ago before finding the marantz a few days later rofl
