Furthermore, I will not be using the VO as I am synchronously clocking.
I changed the whole lot in one single operation.

I will be using the leftovers from the BII in one of my B24, just for the fun of it.

May I look at a photo of this trident, if vendors do not object?

Talking New power

After reading good things about the new tridents and avcc regs I had to order them. Installed them with no trouble. Wow! Best upgrade in a long time. Very dynamic. "Close your eyes and you're there" kind of sound. I2s and now this! Wow! Thanks guys.p:

Do the tridents present an absolute constant current to the preregulator (Placid) and if so, would a well built series regulator work just as well ?

The interrogative is not necessarily related to the predicate. At least it's only one of many facts to consider.

I would suggest reading up on the differences between the two regulator types.

There are a number of factors at play.

Trident does present a close to constant current to the pre-reg.

You could definitely use a series regulator there - the *just as well* part really will probably end up being largely subjective.

I designed Trident specifically for the task at hand. So I like to think it is well suited.

Please I'm from Sweden and English is not my first langage I'm doing the best I can here but I really didn't get that one

Yes I seem to get that from others as well and I'm doing my best to keep up even if my area
of expertice lies in speakers and driver development instead of electronics.
Since we are on a forum and the main idea at such a place is to intereract, asking questions
and so on I'm thankfull for all answers I can get about things I haven't had the time to read
up on yet so please bear with me I'm building tube power amplifiers speakers and a house
as well so time is a luxury.

I have some clues to the differences betwen them and I also have some ideas on how to use
them. Replacing the tridents with series regulators really wasn't one of them.
The one being better suited elsewhere would be the "Placid" putting that one closest to the
"Wave IO" and a 5v feeding (mainly) a dsp chip instead of using them as preregulators for
the "Tridents". I have two "Placids" and two BuffaloIII's and as described two additional 5v loads to feed.

I have also bougth five tps7a7400 series regulators (the evaluation boards) and the plan is to use
them as preregulators for the "Tridents" and "Placids":
I have measured the current drawn from The Placid and it's as constant as anyone could ask for
so feeding that one with a series regulator wouldn't be a problem as I see it. I didn't have a figure
for the "Tridents", that's why I'm asking.
Maybe I'm way of here but as I have learned over the last month or so shunts have a big advantage
over series regulators regarding variations in current drawn.

I'm hoping that my thought's about "just as well" is more clear now.

Some would say that I could skip the preregulator all together for the "Placid" but thing is
I'm going for a separate case for most of the PSU (there will B+, filament psu, transformers
for all and so on in that case and I don't want to send ac over more length than absolutly
necessary) just keeping the smaler parts close to dac's and so on. I'm thinking that keeping the
placid close to the load is a good thing as well

Best regards. Bengt Dahlberg

Check the year.

We have been shipping them for about a year.

thanks, so that would mean that the shipment from 7 May 2012 included the v3 Tridents?
