N.Y.A.L. Moscode 600 Amp

[StereoNut]

Wow. That is one sweet looking amp. It definitely looks like it was worth the 4 month wait. Also I've done what topround said for break-in. I've bought a Coby or Memorex CDP from Target etc and destroyed it letting it play non-stop to break-in equipment for weeks.

Thanks!  I think I have an old $20 DVD player laying around the house that I can use... or how about hooking up an FM tuner?  Will that work?

The Memorex DVD/CD player I beat up on was this $30 thing from Radioshack. I swear after all was said and done I think now whenever I play stuff I hear the mechanism click and it has trouble closing.

With regard to the FM Tuner my preference was to use that for IC burn-in or preamp burn-in. It may work for amplifier break-in but I'm not technically sound enough to know. Part of the reason I used the CDP/DVD player for burn-in is that I have all sorts of burn-in discs from Isotek, Rives and some others. I would rotate that stuff in with all sorts of other music to give the amp and speakers a workout.

Rich helped me find some complex music selections. If I can find the e-mail or PM I will send you what I have. It helped when I was breaking in some Morrow cables as well as my Jolida amp.

  Just remember that the dielectrics need time to settle. So no 24/7 of continuous play. 24 hours on 5 hours or so off. 200 hours and your ready for prime time.
   Enjoy the trip. The Dodd will take 200 hours as well according to other owners.

to save your sanity, you want to run some dummy loads since you're not trying to break in the speakers, just the electronics.

These are your friend in that instance:

Pretty sexy, old friend! You don't happen to have a schematic of the beast, do you? Being new to the hybrid tube/transistor topology, I am curious as to how the tubes are deployed vs. the transistors. Are the Q's used in the output stages or just in the power supply section? And are the monster caps used on the output or also in the PS?

Inquiring minds want to know...

Thanks,

I don't have a schematic.  Maybe others who read this might?  As far as the tech stuff goes, I'm not gonna be much of a help. 

Tubes on the front end and Moscodes (some kind of Mosfet/Cascode combo created by George Kaye, I think?) on the back end.

Hello fellow "Nervosians"... anybody have any answers for my buddy Don on his questions?

Yup; you are correct. Need to register to view them.  Something else to occupy a sub-zero weekend... 

Thanks for the guidance. Maybe I can figure it out when I see some pix!

The big electros right rear are storage for the 90V ss output stage rails. Another smaller pair, black, center of PCB, is storage for the 500V B+ for the tube regulators which are the three center tubes. 390V reg to 4 signal tubes at front.

I don't know what you mean by Q's.

   Good to have you here DonZ. A great place to be.

OK.  I realize that there's two separate threads going on here that I initiated regarding my system: The Dodd Pre-amp one and this one on my Moscode 600 Amp.

For simplicity right now, I'll post here.  I exchanged e-mails with Gary Dodd asking him about break in.  He told me that if I run my tuner through the pre (even with the pre-amp on "mute") it will get in the break-in hours I need and not have to bother anybody else if they're watching TV in that same (family) room.

Of course, running the Moscode along with everything else will "kill two birds with one stone" and I won't have to run my CDP to death in the process!

Needless to say, getting in some listening hours with my CDP is even better.

That's how I look at it. New gear is never so bad that I can't enjoy music, so I just play it knowing that over time it will get even better, then I don't think about it anymore. I don't count hours waiting for the cake to be done. I do let line level gear run overnight though, cranked up high into lowest ohm load I have at the time.

  What ?? No special gold plated Quantum  break in clock ? Good point Rich.
    What is really cool when one experiences a change while listening.

 To Moscode or not to Moscode is the question ?

Do NOT run thed syetm for consectutive days! Play it each day for a few hours at a time, twice daily.

I hope when it is all hooked  up correctly( don't forget to plug it in) that it sounds glorious.

If it doesn't...don't fret it probably needs a bunch of burn in

get a cheap cd player and run it in repeat mode for a few days, don't worry about the tubes...they need to be burned in as well.
turn it off for a few hours every day
Do it for a week! Sounds crazy but it will sound a lot better
