Finally. Got it back, in one piece and working. New laser and some other bits. Burning in. It sounds rather good.There's nothing left of the original machine now except the case, the board, the laser mech. I'm in the process of cosmetic changes: nice walnut cheeks and a lexan top, with some lead flashing glued to the bottom to increase mass, beacuse it's gotten much heavier on the back due to three transformers.

Sounds like you jacked up the radiator cap and drove a new car under it.   :lol:

Now it's time to put on on the shelf, take a deep breath and sit back and enjoy it.  :thumb:

Nope,no tubes. Just strange and wonderful (and woefully price) other kinds. It will need another 100 hours to give its best, by which time I should have the cosmetics sorted and I can finally post some photos.
Most of the parts and all of the work comes from here http://www.fidelityaudio.co.uk/marantz.shtml
and The DOS board, which replaces the op amps and other things, comes from http://www.raylectronics.nl/index_en.html (http://www.raylectronics.nl/pictures/sa8400/SA8400_Outputstage_1.jpg)

You know Shep we have all had a good time joking with you about the amount frequent flyer mile your equipment has been racking up, but all kidding aside, anyone can just go out and buy a good piece of equipment. There has to be a certain amount of satisfaction in having a direct hand in getting your gear to a higher performance plane. In a way it is kind of like taking a backpacking trip where getting there is half the fun. I hope all of the break-in goes quickly and you can get down to some serious musical enjoyment with the new old gear. You've certainly earned it.  :thumb:

I am kind of disappointed that she/he/it didn't get an honorary British passport. I love DIY madness, although it should be called SEDI (somebody else did it). Today the wooden cheeks will get routed so that they sit flush. Then sanded, and polyeurathene (?) d. Now if only the dolts over there would answer me about a Lexan sheet...

If it sounds as good as you hope when all the dust settles maybe you can get it nominated for an MBE.  :D

I got out my trusty Namiki (circa 1985) AC direction finder and got the polarity right. And yes, Dorothy, it does make a significant difference...in the sound. Now I have to open the amp and try reversing the direction of that pesky "audiophile" fuse. Well on the way to having the cheeks done.  :duh

 I'm with ya on the polarity direction finder. It made a huge difference when auditioning the Beacon preamp. The flament power supply when properly orientated made a substanial difference.
    Wood cheeks ? I prefer my cheeks a little softer.

  Actually Shep, nothing. Meaning overall does it sound better ?  Just that simple, leave the audiophile brain outside and bring in the music lovers. Have fun.

  OK then , resolution and detail. More ? Less ? Tonality ? Last but not least imaging and size of soundstage. that will keep you busy for a while.  8)
