Marantz manufacture dates

There's a sticky thread in the Pioneer forum about how to date a Pioneer's year and month of manufacture from the serial number. Is there any way to do this for a Marantz, or does the manufacture date appear on the unit somewhere?

I'm probably not the first to ask this...searched this forum and couldn't quite find an answer to this.

Thanks,
Pete.

Your one-stop source for Marantz data.

Tom, thanks...I actually use classic-audio.com alot, but I'm looking for more specific dates. That site gives the overall years produced for a unit, like '71-'76, but I want, if possible, the month and year of the specific units I have. From the serial number on my vintage Pioneer, I can tell it was made in May of '75, for instance. Just wondering if there's a similar procedure for Marantz's.
 
With Marantz (and possibly others) you also have the variation of the market that the unit was built for. A prefix, and possibly other info on the rear nameplate will tell you - "C" for Canada, "U" United States, etc. The Canadian and export models also have fuses in circuits the US models do not, due to regulations in those countries.

I have a Canadian 2250b. Curiously, the rear nameplate is held on with screws rather than rivets. Underneath that plate, it says "Marantz 2275"

There was much in common between those two models, but that was a bit of a surprise! :scratch2:
 
date stamps on chassis

You can find the date (month + year) on the chassis of the unit.
You'll have to remove the top cover, and search for a stamp on the chassis.

After 30 or 40 years, those stamps are not so readable.

Take a look at this post, second pix (front left corner of the unit)

Tony and all, thanks for the tip. I looked at the pic you mentioned, and there the year appears on the meter housing. On my 2245 the year appears on the chassis, on the rail just above the tuning wheel.
It says "1974 92". Not sure what the interpretation of the "92" part is...

On my 2226B, the date is also on the top of the front rail, but over to the left. It reads "19780422". The "0422" part is more clearly a date format, but I'm still not sure about that. Any theories about the number parts that come after the years?


Thanks,
Pete.

Hi Pete,
"0422" is the month and the day so your 2226B was built in April the 22nd 1978
And your 2245 on September the 2nd 1974.

Excellent info Marantzbe. Sometimes the date of manufacture is stamped in ink on the inner top edge of the faceplate. You have to take the cover off to see it.

Yes you're right sometimes you can find the stamp on the face plate:thmbsp:

Thanks. Yes, I suspected the "0422" was April 22, but the "92" seemed less clear as Sept. 2. If it's known that they typically put the month/day as well as the year, then that seals it. Anyway, I'm glad they dated these units; I get alot of pleasure from knowing when these vintage units were made.
 
you can't determine the production date from the serial number on any vintage Marantz product. I know close to nothing about Marantz products after 1980 so i can't comment on those....

On Vintage Marantz units there's usually a stamp ( as mentioned) on the upper chassis edge (right) or elsewhere on the chassis -

The production date is usually stamped there - but not always in the same format - you have to use your sense of reality to determine eg. 1978 2 21...? hmm.....

the worst og at least most difficult part is when the Marantz company (Standard radio - Japan) used a totally different format - relating to the "Showa Era" - from the the year that the Japanese Emperor Hirohito reign period. (1926 - 1989) - they could stamp 50 12 21 on the chassis. Hmm..... The Showa era started 1926 at the year "1" - og the 50'th year thereafter is 1975. So the Marantz unit starting production date number with "50" is manufactured i 1975. a Unit from 1974 has "49" as initial digits. The digits after that is still month and date. got it?? This is not only for Marantz Japan electronic products but also for Japanese goods as a whole.

That is for the tubed units and very early SS-units aswell (especially the 7 and maybe the 7T - 15 - 16/B - 18 - 19 ) ehh?

Ok. I’ll check that out. I know there is another thread on the Marantz 2215 speaker. JBLs seem to be best. Any other suggestions including brand and wattage? I don’t want to over/under power either receiver or speakers.
 
Well, I decided a cream of the crop receiver needed the cream of the crop speakers. So I hooked up the Sonus Faber Concertinos to the Marantz 2215. Sounds “Cream of the Crop!” I didn’t know if I was doing the concertinos justice by just supplying 15 watts per channel, but it sounds amazing.

I see a website here. However, the models that Marantz made after the acquisition of Philips are not listed.

Ik have two models of PM310.

Regarding that classic-audio.com site, it says that the 2325 production ended in 1976, yet I've got one with a date code of 76-12-27. I suppose hifiengine has a better idea of when they were produced, saying they ended production in '77. Would this make my Marantz one of the last 2325s produced?

Sure sounds like it. What is the serial number? According this database of estimated production numbers at the link below, there were 109,262 2325's made (estimated). That is second only to the 2230 in total production. That seems really high to me. That unit certainly doesn't seem as common as the 2245 and 2270.

I'll give it a look when I get home, I'm on Christmas vacation at the moment.
 
Finally got around to looking, the serial number is U190116. From the link, the unit was made for the USA and is likely the 90,116th unit produced (since I don't think they made 190k 2325s...).
