Marantz 1060 Recap

CohibaJoe · Jan 15, 2014

OK...I know...not another 1060 recap...

Finished up a Sansui AU-517 recap last weekend:
http://www.audiokarma.org/forums/showthread.php?t=566203

Around 70hrs on it... :music:

I am going to HOLD my review of this... :king:

I picked up this 1060 last month to do a comparison in another thread with the Sansui AU-517. I will post my review in the other thread..maybe I gave it away..:scratch2:

Thanks to bktheking(1060) and Pat's(2230 thread) for Parts list...Looking at Threads from bktheking, Pat and Sr.Byrd.

Parts are in and I am going thru this now...bktheking uses more Films as to Pat's use of ELNA Silmic II through out and Preamp Board with AMRG 390ohm, WIMA Films....My 2230 is more in-line of Pat's 2230 recap. So it will be 2230 vs AU-517.

Pat has another Thread "Electrolytic Capacitor Shoot Out-"Final Fantasy" which I am watching. So the PS board on the 1060 will be LAST.

This 1060 has Engraved Front, Champagne Plate, Black Speaker connectors which seems a Early Production unit.

Parts:

Main Caps: (1) EPCOS 10000uf/100v, (2) Nichicon KG 6800uF 63V

I am really looking forward to your rebuild, I know you have gathered much knowledge with the breadth of equipment you tackle. :music:

CohibaJoe · Jan 26, 2014

OK..time for a update on Completed Boards:

Power Amp
Power Supply
Phone Amp

Waiting on the Films for Tone/Pre-Amp and (2) 6800uF 63V Nichicon KG.

I also have ordered MUNDORF EVO Aluminum + Oil Films for the Tone/Pre-Amp and Phone Boards.

This will be Added after everything is in place and have 100hrs on the Caps. I have used these with Mac 4100 & Luxman M-120a and like the Tone out of these.

Just to make this Clear....This was before Recap.

1st: I noticed just a BIT of lower sound on the Right Channel. The Left Channel is Bit more louder/detailed. No Deal breaker...But just because it's there I am looking for 100% Clear Sound.

You can see from the Pic 1 the set of Outputs. One channel has been replaced with Motorola HEP704.

So...I need to order ON Seimi MJ21194G to replace all 4....Other mouser order going in...

2nd: Picture 2....Need to change this as the Left side is bulging. What can I replace this with?

1060 re-cap

Way to go!!!
The most fun I had in the past few years was to re-cap my 1060. I took my time and due to one stupid mistake it didn't work. After getting photos from other AKer's I found my error and fixed it. Glad I didn't blow anything with the error. I had taken "before" photos but of course my error was not seen in my photos.

It sounds great.
The real pleasure is that it sounds better than I remember it sounding with the old caps.
Cleaner and tighter.
And I did it myself.

Is where I got answers to that question. I haven't reread that thread so if the answer is not there let me know and I'll search again.

72-VY2103M63Y5UG63V0 is the Mouser item I used.

I guess you appreciate that I look at your rebuild threads now.

Does this unit have heat sinks attached to the heat sinks? What is up with the aluminum strips over the transistors?

Yes...Trans with MICA Insulator attached to Black Heat Sink then Aluminum Heat Sink holds Trans with (2 screws).

This is a Early Model. S/N: 1063

25hrs and it Never Fails to amaze me....

How the ELNA SILMIC II open up from a Bud to a Flower. :music:

Once 50hrs..Sunday....Will put in the New Main Caps.

Blue Shadow · Feb 1, 2014

Well I just turned on the silmics in the recap I did. Minor caps, nothing serious. Got the amp playing through some cheap test speakers. Guess I'll wait to hook em up to something good.

patfont · Feb 1, 2014

me too: and just when you think it sounds awesome, it gets even better!

All this time on this site...I never said what my test speakers are...B&W 685B

Blue Shadow · Feb 1, 2014

I can't mention my test speakers as the ones in use right now are car rear shelf speakers, I think. We don't do car stuff. But if they blow up, (275 wpc amp in use) it is NO loss.

Early SN had to doulbe heatsinks, they dropped them in the production of later model sn's.

CohibaJoe · Feb 2, 2014

Main Caps are in...

Making my Power Amp adjustments:

1. Connect VTVM across R747 Trim R729 7.5mV
2. Connect VTVM across R748 Trim R748 7.5mV

I am at 8mV on each resistor.

3. For the Speaker terminals Clipping levels. Since I do not have a Scope.
Adjust R723 for approximately 29VDC at J715, adjust R724 for approximately 29V at J716, both with respect to chassis ground.

I am at 29VDC

Need to put around 50hrs.

Next post will be a Sound Check.
