sorry to thread jack.

I'd heard that as well. Of course, I never had the courage to get inside the raptor. Always worried that I'd bugger up the finish on that beauty.

Someone got a definitive answer on this? I'd also be curious about what the straight story is.

As for owning cans for 'moods'...my sentiments exactly. Wonder what mood an L3000 or PS-1 would suit?

Arnt all the caps in the PPX3 mounted upside down???
post #94 of 104
i take it back, i think at least some are upside down, as at least my PPX3 has the RCA jacks on the left side, which would place many of the caps upside down. unless the orientation of the new amps is different, of course.

Edit: Edipis... those were good links regardless, I have never seen images of the new PCB version.

I guess the electrolytics are:

i guess that, in the end, all we can say is that if mounting caps upside down is a bad practice, more than one maker is guilty of it. i'm not going to sweat it, personally.

Hi grandenigma1...
I have worked for over 15 years with all kind of pc brds that were build & designed for the military & civil aviations. Many of these electronics were housed in an aluminum chassis that had a mother brd in the bottom & more than 10-20 pc brds plug into it & secured. These brds were put standing up vertical, which means all the caps & components were in horizontal line.
Ones that big aluminum chassis was given to the manufacturers of the civil or military aviations, it was was mounted in some upside down in other side way.
Which means that most of the time the components were up side down.
& by the way to those who have in mind to get into further argument regarding the Raptor or any Ray samuels amps, I would say that I have stated many times that I use military components, parts, from resistors, pc brds, wires, solder & follow the military way of putting things together as to show their value for easy inspection in case of malfunction, BUT I do not claim that any of my amps will pass the military stress test at all. How many amps have you seen with their components up-side down, if you can't remember, let me refresh your memory, one of the greatest designers who deserves the upmost respect here & in the high end world, Pete Millet, one of his best amps that I have ever heard, Wheatfield h-2, the components on the brd are upside down, does that mean anything, not at all, that amp is been in the field as long as we have heard of headphone amplifications & yet still sounds as great as the day it was made.
I hope I made my self clear.

Ray, thanks for clearing that up. No offense was intended, I simply wanted to clear up what I had been told and why I said I assume it is not an issue.

So there really is no ideal way to orientate caps?

I work on machines that are between $150,000 and $750,000. They have circuit PWBs that are double and triple layer. A lot of them are mounted sideways and upside down, and operate in extremely hot or cold environments.
Some of the caps are upwards of 4,000uF, and although boards fail, and since they are made by unions, I am not allowed to troubleshoot down to a component level. Boards not working...replace board. However, some of my machines are 8 years old, and have never had PWB failures.
So, I'm not sure if caps that are mounted upside down, would present a problem. A lot of times, when you carry a PCDP or a SR-71 or even an altoids tin amp, they sit in your car or backpack upside down.
What about the caps in Nasa spacecraft, or submarines...they sit in all different directions.

If it's an electrolytic cap, you want the positive and negative sides to be connected properly (reversing these is bad). However, that is electrical orientation, not physical. A capacitor really doesn't care what position it's in. It's a sealed unit, and will not "leak". The only capacitor I have ever seen fail personally was mounted in the normal "rightside-up" orientation on a board. The orientation had nothing to do with the failure.

I'm just catching up on this thread, and other than the usual battles, it's been a nice read. Very informative.

To answer the question, I love Ray and hate Mikhail. No wait, I love Mikhail and hate Ray. No wait, what was the question again?

Oh ya, it was about their amps, wasn't it!?!?! Both are outstanding. I've owned two amps from Ray and two from Mikhail. Excellent build quality and sound quality, lovely cosmetics, world class customer service. You can't go wrong with either company. More than anything, they're both really great whom I'm happy to call friends.

Get out to a meet ASAP and let your ears decide. There are now more than 100 replies to this thread alone, and countless others that you can read about the products these companies offer if you dig around the archives here at Head-Fi. But none of that will mean as much as what you hear for yourself.

OK, with that fine post from McManus, (to put things into proper perspective), can we put this melee to rest, and call a truce?
I hate it when you guys fight.
