What a Difference '70s vs 80's Marantz!

So last night I continued my re-capping of my 2230 (~1973 production), and now I'm getting into the heart of the AM and FM sections, so it will be apart for a while - lots of caps in there, plus boards need to be partially disconnected for access. Since I didn't want to work in total silence, I reconnected my Marantz MR1150 receiver (bought it new back in the very early 80's - my first "decent" receiver). What a difference! FM reception is very poor compared to the 2230, and the sound of the MR1150 is lousy in comparison - tubby bass, fuzzy edges around everything, lack of top end clarity. If the 2230 is a 10, the MR1150 is about a 3. The 2230 was miles ahead before the recapping, now it is just on another planet.

Amazing how fast things came apart for Marantz. The MR1150 weighs much less (indicating less iron), has a much thinner, integrated-style faceplate, no gyro-tuning wheel, crummy spring-clip connectors, NO BLUE LIGHTS, Darlington transistor pack instead of discrete output transistors, etc. You can sort of see it behind the 2230 in the attached picture.

I do not like 80's Marantz at all, and even their new stuff doesn't do it for me. Pre 80's Marantz for me. I wish they'd come out with a new line of HiFi gear styled after their greatest line up (22xx) or (4xxx).

Hows the re-cap going?
 
The re-cap is progressing nicely

So far the filter and output caps, regulated PS board, amp boards, muting circuit board, FM detector board and AM board are done. Next up is the FM multiplex decoder board, then the Tone Control board, then the phono board. Lots of electrolytics in this thing (I believe I counted 70).

I have done listening tests after each board is completed; at one point I had it with one amp board done and the other stock (that's how it is in the attached picture above). It was very easy to tell the difference between the channels when I played a strong FM station in mono - the recapped side had tighter bass, clearer midrange and a lot more air at the top.

All the cap values are identical to stock with the exception of the big filter cap (went from 4700uF to 10000uF) and the output caps (went from 2200uF to 4700uF, with 1uF Solen bypasses). I also replaced the mylar caps on the amp board with metallized polypropylene.

Wish I had the time to do the whole job at once, but little things like work and life keep pulling me away. :D
 
Are you compiling a complete recap electrolytics list as you go to spare other 2230 owners a little work?

Good job, BTW! :thmbsp:
 
I see a lot of the later Marantz gear in the wholesale market here, and I know a few of the earler "cheaper" ones, especially the TOTL ones like the SD-9000 (I think that is the right prefix???) do have their buyers, but every time I pick one up and look inside it, I put it back down... you are right: there is no comparison with the earlier 22XX (and other silver-era) series.

I discussed this with one small retail dealer here, when I saw one or two of them in his shop. He told me some people just wanted something "retro" and decent, and didn't want to pay the premium for better sound. They were buying a decoration as much as hi-fi, so they were happy with these. That explanation, at least, made sense to me. Perhaps someone would want one out of nostalgia, or because they can't find anything better.

In fact, these things are not always 'bad'. In fact, they do sound much better than many of their contemporary boomboxes and a lot of the lower-middle gear sold since then. But compared to the better, earlier pieces and any real audiophile gear, they fall way short of the mark.

It's really sad to think that this happened to the once-proud name of Marantz, a name that once competed head-on in the marketplace with the likes of McIntosh.
 
It all depends on what you find from the 1980s

I do not like 80's Marantz at all, and even their new stuff doesn't do it for me. Pre 80's Marantz for me. I wish they'd come out with a new line of HiFi gear styled after their greatest line up (22xx) or (4xxx).

Hows the re-cap going?

While I do love the look and sound of my earlier Marantz gear, the 80s saw some great stuff come out. If you are talking about the crap other companies made with the marantz name slapped on, then you aren't giving them a chance. Yes the 70s marantz stuff was great. But purists also say the superscope 22xx series could not match the saul era 60s gear. Opinions vary, but i'd like to give some history on the finer things marantz did in the 1980s. In my opinion I would say the late 80s/early 90s saw some terrible badge jobs from marantz.

SR9000G
While it was introduced in 1979, this is the style Marantz took in the early 80s. Metal knobs, metal faceplate, and a massive heatsink. Its rated at 130wpc rms. Some have tested 150rms. The quartz tuner locks onto stations like any of my 22xx and 44xx gear. The pre-sets are a thing of beauty as well. The sound is a bit softer than my re-capped 4400, but then again, most of the caps on this receiver need to be replaced. The looks are subjective, but i like it, its different, and the fake wood case polished up beautifully. I can tell its not real cherry, but at first glance, people are quite impressed. I have an issue with a dirty pot, but after fixing the burnt out left channel from a shorted speaker wire (previous owner)...i wont complain, its the most powerful 91 dollar Marantz in my collection.

The CD-73 pictured at the bottom of the stack weighs a good 20 pounds. It features the first generation cd transport from philips. At the time, it used a 14 bit processor that was considered inferior to the standard 16 bit processing. The dudes at marantz developed sound shaping circuitry that made this player sound as good as the much more expensive ultra high end philips lhh-1000. Mine is used every day for hours without fussing. It plays burned cds, scratched cds, and sounds great considering how archaic the dsp technology was back in 83. The accuracy of this transport is what makes the player do more with less. If you look at most of the CD players marantz put out under the philips era, you will see some very highly respected items.

The Marantz 6370Q was introduced in 1978, again...the champagne faces we see on todays Marantz gear can thank this design language. While its not audiophile by some peoples standards, its direct drive, quartz lock, and auto return. I like the way it sounds, and its a great match to all the other 80s marantz gear i have. I like this unit better than my 6300

The dynascan era was the last horrah for marantz before they went to their current era of fine machinery. Below is the PM-94. Delivering a quarter of its rated power in pure class A before it automatically switched to class A/B. The toroidal transformer is HUGE, the filter caps are huge, and the chassis is copper plated. It has beautifully finished oak sides, and draws a healthy ~6 amps. Mine sounds fine, but lacks some bass that I think a re-cap can fix. I run a fan on it since class A gets too hot and cracks the cold solder joints. The smaller "quarterA" family amps did not have this problem.

...I can add more once I get home....but ill just keep buying 80s marantz stuff as long as you guys still see it as crap. less competition :D
 
Kind of ruins the myth that 80's and up is garbage doesn't it? I love my 1980 SR8000, however it was the restoration by CATRAFTER that really made it shine!
 
That 9000G isn't bad at all, maybe there is still hope for me and 80's gear. That PM-94 is pretty slick looking as well.

But that 140 keeps making seductive faces at me :music:

Different strokes for different folks I guess.
 
One concern about the 80's and up gear is some of the IC's and the like that were used are unavailable now and there are no substitutes. If one of these components goes bad, unless you can find a donor, you are out of luck. I know I have said No to some tempting 80's gear for this reason.
 
So last night I continued my re-capping of my 2230 (~1973 production), and now I'm getting into the heart of the AM and FM sections, so it will be apart for a while - lots of caps in there, plus boards need to be partially disconnected for access.

The MR series is not a 80's production, they were made an designed in the late 70's.
The code for the receivers in the 80's an later was SR
The MR 215 , 230 are in fact a copy of the 1515 and the 1530, they were the Botl for the Marantz gear at that time.
The crapiest products were made between 83 and 90, remember the "Legacy" serie, made in China or Korea.
In that period they have also produced wonderfull machine
Esotec Serie
The PM84 - 94
The famous CD-73

Today's Marantz amplifiers and receivers are very well made and sound excellent, especially in the Home Theater arena which they are designed for. Certainly not the 'Martini' sound, but Front Row matinée sound.
 
Thanks for all the great pictures Secondslc. Does that 140 ever get lit up for some use?

The 140 has a blown channel. Ironically, more of the "good ole" marantz gear I have has problems than the "crappy" 80s stuff I have from them. I can't say I blame Marantz, I buy them broken, repair/restore them, and learn in the process.

I do use one of my 240 blackfaces. But I really want to use my 140 to see those meters bounce.
