Dodd Battery VGP Tube Pre-amp and N.Y.A.L. Moscode 600 Hybrid Amp

[tmazz]

feel is most likely the Moscode 600's seemingly limitless "horsepower".

Bill while the Moscode's output is not limitless it does have significant horsepower. Since mine is pushing 600 wpc into the T4 ohm Thiel CS-3.5s in the mini-mancave I have always liked to respond to questions about its output by telling people that it was a 1.6 horsepower amp.

Is that with STP or without!?! 

You pay me now, or you pay me later......

Or in the case of this amp, you send it now and you wait 'til later.

Campy,
Your system sounded fantastic today. Night & Day different than your old Naim system... for the better, by far (at least to my ears!)

Dynamics, detail, musicality, etc... 

Stick a fork in your ass, you're DONE!  Actually just get some sound absorbing egg crate to eliminate that annoying Moscode convection fan noise... 

Congrats,
Pete

Congratulations Bill!

Thanks, Pete!  I'm glad you and Rob got a chance to hear it today.  Yes, there's a big difference from what I had and where my system is now.  I was happy with my Naim system and all of the incremental changes along the way that I made for 25+ years.  It (my old system) served me well and it certainly wasn't a "slouch" sonically, but compared to what I'm currently listening to, there really is no comparison... and  (like you said) all for the better!

I will hunt down some of that "egg crate" sound absorber stuff and place that behind the Moscode.  You can't hear the fan with the music playing, but it would be nice to quiet it down anyway.

Thanks for coming over.

P.S. to Rob - Thanks for adding to the "eats" and bringing dessert!

P.P.S. to Pete - The reason my system sounds so good is because (except for the Dodd battery powered Pre-amp) it has T.W.L. Power cords throughout!

Congratulations Bill! 

Thanks, Rich.  Next time you're up this far North, you have to stop by for a listen and some home cookin'!

 Bill how many tubaroonies in the Moscode [5] ? What types ? I agrre with Carlman and Joe. Prudent to wait, lets see how long you can put off the nervosa.

Hi Charles

Sorry for such a delay in answering this.  I just couldn't find the right scrap of paper with the notes I wrote down from one of my many conversations with George Kaye until now.

The N.Y.A.L. Moscode 600 has 7 tubes in it as follows:

 • The two outer-most tubes are 6GU7's as Diff. Voltage Amp tubes, I think? (George says that using 6FQ7's here can sound a bit harsh.)  6H30's can be another upgrade choice, but they're much more $$$ expensive.

 • The 2nd. tubes in from each side (counting from the outside/in) are also 6GU7's as Cascode followers.  There's a matched quad of them in my amp. (George said that using 6FQ7's in this position is acceptable, unlike the outer most tubes described above.)

 • The next tubes in line are the BIGGER 6LU8's, which are High Voltage regulator tubes.

 • Lastly, the one middle tube is a 6DJ8 as a volt Regulator.

I hope this helps answer the question for you.  Oh, BTW - I have not even thought of rolling any tubes yet!!!

I've found that tube rolling on my Moscode is rather subtle, whereas tube rolling my Dodd pre can create major changes. We don't have quite the same Moscode, but the Dodd's are very similar in sound.  I'd be very interested to see if your impressions  parallel mine.
