Default build it your way then... I don't care.

aaron,
I'm not suggesting you skimp, or build a "cheap" amplifier, or compromise in any way. That would be absurd. I'm merely suggesting you use the right tool for the job. There is no prize for building the most expensive amp, and money does not gaurantee good sound - although you seem to be equating the two.

I was just trying to help offer a viable alternative. And I think $550 for a SET power supply is a lot of money. Sorry if pointing that out annoyed you.

Finally, I would just add that I have PSUD installed on my computer - and it does not perfectly model reality.

I could hear the difference when I placed 5 CD jewel boxes on my player as opposed to nothing on top of the player, no kidding. I'm not sure if this smilie is not reserved for moderators use only

Have you tried placing random items from around the house on top of your cd player to see if you can get it to sound better? A friend of mine has a cat that likes to sit on top of his cd player... I wonder how that effects the sound.

Here are some descriptions of my experimenting with a player. When I checked it now, it's indeed 3 boxes and not 5. Joel must have been talking about me.
were do i find some nice spikes?

Was that you Peter??? Haha, sorry for making an example out of you - it just struck me as amusing.

I have learned to place my dog on top of mine. The 100Hz region seems more warm and "wooly" now.

Well, this whole tube amp DIY thing for me started out with the Baby Ongaku, and it was Gordon Rankin who sent me the initial power supply schematic with two chokes, and I trust his ears :-)

The total is costing far too much, but I think it's worth it..

Power supply $550 (Tango MX-175, LC-10-200, LC-15-150)
Interstages $264 (Tango NC-14)
Capacitors $180 (all Solen)
Resistors $50 (Audio Note)
Tubes $200 (6900 pr, Sovtek 2A3, Mullard 5AR4)
Output Trannys $600 (Tribute amorphous)

around $2k for the project. :-( .. But alot of the cost is getting some of those components from Japan, for instance, the power supply is only really US $380.

Getting real african ebony wood pieces for the chassis and copper plate.. but that's not for a while.

No complaints with the Tango NC-14?

Here are the simulation of my PSU (bottom) versus Joels (top). I do believe mine is worth the extra money.

Please keep in mind the following qoute from Joel: "Finally, I would just add that I have PSUD installed on my computer - and it does not perfectly model reality." .. Obviously this is true, but the differences are large enough that even a significant margin of error on the part of the simulation can be overlooked.

Finally, Joel, I wasn't annoyed, no worries :-)

Yes, the millivolt of ripple reduction is worth $400....

I stand by what I said - your power supply is overpriced, and overdesigned for this project.

Best of luck. I'm sure you'll be happy with your amp.
