Marantz Service Manuals

I receive a lot of emails asking if I have copies of certain Marantz Service Manuals.  I do have many different manuals and I don't mind sharing with the visitors of this site.  Emailing copies does take a lot of time, so I decided to start a page where the manuals can be downloaded by anyone who needs one.

I will add more each day until all of them are available. I have already add the manuals for the marantz 1200 and 1200B.  I chose these because they were the first manuals I got.

I have also opened a Guest Book page where visitors can leave comments for myself and others to see.  I will practice freedom of expression for all views and ideas that are posted in the guest book.  I also will remove any comments that are inappropriate, hateful or profane.  

If the guest book becomes a problem, I will remove it.

Visitors can also use the RSS Subscription Feed to receive automatic notifications when new items and updates are posted.

Marantz 170DC Finds a New Home

I had a new arrival last week, a Marantz 170DC Power Amplifier. I am always on the look out for another amplifier, especially if it's a model I don't already own. The 170DC and a 300DC have been on my want list for a while. The 170DC's seem to come up for sale more often that the rarer 300DC.

The 170DC's were manufactured between 1977 and 1980 with a production of somewhere between 2 and 3 thousand units. This unit came from the original owner and has been in use up to just a few months ago. Its overall condition is easily a 9.8 out of 10. The face plate is clean without any marks or damage.

The amplifier itself is all original and has not had any work done to it. I haven’t had much time to listen to it yet, but what I have heard so far sounds great. The 170DC has twin meters on it face and this unit had several burnt out meter lamps. I though this would be a good time to try out some new fuse style LED's that I found on line recently. You can read about these in my work bench section.

So far I have paired the 170DC with a Marantz 7T preamp and my Pioneer HPM100 speakers. The 170DC has plenty of power at 86 wpc. I'm not sure that the 7T is the best choice for a preamp, I'm going to try a Marantz 3200 preamp this weekend. It is closer to the 170DC design wise than the 7T.

I will have to find one of the recommended preamp models, 3250, 3250B or 3650. Of the three models I think the the 3650 would be a very cool choice to pair with the 170DC.

I have several weekend projects planed in the workshop so I'll be sett up the 170DC there and racking up some hours with it. I hope my neighbors like Van Halen as much as I do.

New challenges for 2012

Some times my world becomes too busy for words, like everyone it's difficult to find a balance between family, work and hobbies. I have been very absent from my audio hobby and this web site since June last year. My business has been crazy busy which is a good thing but doesn't allow much time for hobbies or adventures.

I think I have found a balance between all of the demands in my world and I look forward to more audio adventures. I have been able to acquire many interesting pieces of equipment over that past six months and a new year brings with it a new budget for bench equipment.

I will featuring some of the new test equipment I have purchased to replace well used and well loved old equipment. These will include a new transistor test, a new audio oscillator and new desolder tool. The Hakko 808 has become my most favorite bench tool ever.

Some of the new audio equipment will include the repair of my Marantz 510 amplifier, rebuild of a Marantz 3300 preamplifier and a through look at a Marantz 170DC that arrived just before the holidays.

I am looking forward to all of these projects and more in the coming year. I would also like to hear from more of the visitors of this site. Your questions and ideas are very welcome and I look forward to hearing from all of you.





Niles Flee Market Find

Usually when you hear someone talking about their most recent flee market find, it's some really great piece of audio gear that they just couldn't pass up. My weekend flee market find was this great vinyl shop I didn't know existed.

Last weekend was the Niles flee market. Every year on the last Sunday of August the Niles district of Fremont, California puts on their famous street flee market. Niles was once its own town and is often referred to as the Hollywood of the Bay Area. It was once the home to the Essanay Silent Film Studios which featured silent movie greats like Bronco Billy and for a short time Charlie Chaplin.

Niles is now the home to the Essanay Silent Film Theater and Museum. Each Saturday evening they show classic silent movies, often with live piano accompaniment just like in the old days.

For the flee market the whole downtown is full of vendors and individuals with all sorts of collectibles and odds and ends for sale. The really cool part of the Niles flee market is that it's a community event with the residents selling their treasures on their front lawns.

We showed up early to get a jump on any good deals and began hunting for who knows what. As we turned down one of the side streets I spied a vinyl shop. I visit Niles about 3 times a year, wandering through all of the antique shops looking for unique treasures and I had never seen this shop before.

The shop is named “needle to the groove” and is owned and operated by Dan Bernal aka DJ B.


Dan had an outside space set up for the flee market and the shop was open too. I looked around for a while and there was a really great selection of albums and 45's all divided up by music style. The walls are covered with graffiti murals and Steely Dans Aja was playing on a set of Sansui speakers.

I asked Dan if the shop was new, and to my surprise he said it has been there since 2006 and he has just opened a second store in the Centerville district of Fremont.

I was able to spend some time talking to Dan and it's easy to see that he has a real passion for what he is doing. He told me about how the murals were painted by some well know 'taggers' who are now in their 40's and have a following and reputation for their art. One of the murals was painted by an artist that has also painted a mural in the headquarters of eBay.

Dan talked about how he spends a lot of time traveling around the Bay Area looking at and buying vinyl for the shop. He told me about recent trip across the bay to look at a collection that the seller inherited from a family member. There was over a thousand albums but only a few hundred made it back the shop. Dan is particular about the quality of the vinyl he buys, it has to be in very good condition to make it into the shop. Wore and scratched albums are passed by.

The shop features a wide selection of musical tastes including Rock, Jazz, Funk, Soul and Hip Hop. Many of the shops customers are younger and just getting into vinyl along with cassettes and 8-tracks. Dan said that recently a pair of teenagers spent over an hour looking through his cassettes and leaving with quite a few.

Needle to the groove is the kind of shop that encourages you to stay for a while. Hanging around and getting into the place isn't looked upon as loitering, it's actually is encouraged. Dan offers a cleaning service to it's customers, $1.00 per album done while you shop. He also has a machine which can flatten out warped albums.

While any trip to a flee market can be full or surprises, discovering Needle to the groove was a fantastic surprise. I went away feeling that Dans mission to bring vinyl to his community was a worthy and successful mission.

Sometimes everything happens all at once

Just a short entry to let everyone who's sent me emails know that I'll be back to posting new item shortly.

A month ago I decided to move my shop to a new location after 21 years in the original spot.

This of course is a lot of work and everything takes longer then you could imagine.

Business is busy and there's so much to do. In the long run the new shop will move the business forward for the twenty years.

I'll be back soon with lots of new happenings from over the summer.
