Marantz 1180DC vs Sansui AU9900

Call this a labor of Love. My efforts were not designed to add value in the eyes of anyone. My wish was to build the best product I could within my means. I revert back to an earlier statement. Sort of. Listening is believing. Peace
 
Look, at the end of the day, do exactly what you like to it, as long as the device remains safe. But, if you ever sell it, you are responsible for poor workmanship or changes to the device that compromise safety.

This is an absolute mess. Who is responsible for it? If 'Jimmy' did it, he needs to shut up shop immediately. If you did it, for god's sake, re-do the joints and insulate them.

I also note the original 40 year old DC coupling switch caps were not replaced...
 
My man. You seem to be quite the expert on many things. I really wasn’t aware that my amplifier was such a disaster. I will go tomorrow to see the technician that has performed small miracles with other gear that other “loudmouth experts” could not fix, and tell him to close his doors. When he asks me why, I’ll tell him that some guy on the other side of the world said he was incompetent. Then I will take it to the salvage yard and have it destroyed, since it isn’t safe to keep in the house. While I’m at it, I’ll contact all the high end, exotic audiophile speaker manufacturers and tell them to recall all their hi end speakers for “redesign”, cause they don’t have protection devices on them. That seems to be going on in another one of your sermons.
Seriously, this is supposed to be fun and informative. Why not let people enjoy their moment, share their experience, and let others join a friendly discussion. I look at the Marantz, listen to it, study the pictures, and am having a hard time believing that it is That Bad. That would be an oxymoron. Your comments, aside from being borderline slanderous, are just not credible. Have a couple drinks and unwind. I really didn’t mean to offend you this much with my “absolute mess”. Peace
 
... But when Jimmy showed me the skinny little ground wires inside the amp, and we took a closer look at the lamp cord bringing in the juice from the outlet, I knew we needed to remedy the problem.
If you think the wires inside the amp are skinny, you ought to see the size of the wires inside the power transistors:

Of course, they're fine for the purpose, just like the original wiring in the amp. Current-carrying capability of a wire is inversely proportional to length and proportional to diameter, which means a short thin wire can carry as much current as a longer thick wire.

Well I think all of what you did is pretty cool, now I want to hear and see it please upload a YouTube video for us all to appreciate...
Play the Sansui then switch over to the Marantz with the same piece of music you choose.
Check out the thread that I just participated in a couple of posts of mine back where I uploaded several YouTube videos of my equipment, that would be a good spot for you to upload or just start a new thread it's up to you
 
@Jeff Jacob

Are the Nichicon main caps Gold Tune or Super Throughs? They don't look like either. What's the green ring on the bottom?
Do they fit the holder or is there an added spacer? I would have upped the uf and/or voltage to get ones that fit.

I agree that the rear mounted heat sink is useless and unattractive.

The binding posts and RCAs look great.

Glad you are enjoying it.

It isn't, but the culture here tends to favour restoration and preservation over resto-modding.

Not everyone though. My '64 Corvette used here for the filming of "Wheeler Dealers."

Sorry for the late reply. Here are some pics of the main caps. I just had some revisions made to the amp and got a chance to snap these pics. I had the volume control taken apart, cleaned, lubed and repositioned. It has a much nicer feel to it now and no more scratching.
 
I like to see people's mods, and I second the upload of videos of both machines in an A B comparison . (I have a Sansui 9900). I like threads about units where the owner appears to be in a "how good can I make this" mode. Imagination and somes-good mores better creeps in, but it's all part of the fun of a resto-mod.

Always entertaining how expensive power cables give a twist to a conversation.

My biased suggestion would be to play Dark Star from the Live/Dead album on both.
