Has anyone seen those new, low noise, low inrush and Fully Encapsulated toroids from the Plitron.
I am a litle concerned about the price but othervise they looks so
good. Comparing them with the standard ones from the same company at the way diferent price, I am confused. Do they really
deserve that price?
(particulary when we are talking about 2 Aleph 4 - monoblocks).
Any input appreciated.

Aside from the shielding and noise testing, I believe that one
can do the same thing by wiring the two 115V primaries of
a torroid in series for 115V operation. Of course, you have
to have secondaries that are "double" the desired voltages as
they'll be putting out half their spec'ed voltages. On my
"to do " list is to actually try this and see what the regulation
and current output look like in practice.
The series wiring of the primaries will allow the core to run
with less flux density and thus there should also be less
stray magnetics.
I'm perplexed as to why Plitron thinks they can get such a
premium price for these "low noise" transformers

You mean the new LOW NOISE or the Standardones
Any experience with thouse new "LOWNOICE LOWINRUSH and fully Encapsulated" ??
500-600 CAN$ for 1500VAC a pcs.??????

Well if your building a high en aleph amp class a design and that will run top end and you want crisp clean noise free THEN THAT IS CHEAP ..
what yuo payfor is what you get

Thanks Brian.
So if I need for my Aleph 4 2 x 40v , what should I ask Plitron for. 2 x 40??? (as they are a litle "fogie" about off load values)

Thank you Peter. I appreciate your opinion a lot.
(BTW Peter I've got the 4 r-theta heatsinks same as yours, thanks)

I always use Plitrons (as well as Madrigal). I just don't think the price of low noise ones would justify the possible benefit.
How much for heat sinks?

A decision has been made.
I am going to get a normalones (standardones).
1000VAC ; 2 x 40V for each monoblock of Aleph 4.
Thanks a lot .

For heatsinks? Well ( 4 x #65340; 11" long each) 350 CAN$
It's not that bad, hey? I think this shuld be enaf for my Aleph.
Sorry guys , it is a litle bit a way from the topic.

It would be a shame to pay more for transformer than for heat sinks. Also it seems like the price didn't change much in the last 10 years.😉

As you know the size of those heatsinks, what do you think are they sufficient for Aleph 4, two monoblocks ofcorse, standard gain configuration. ???
Have recived PCBoards as well. They look Great. PRO.🙂
Time to start hunting other parts. (Holco, Panasonic etc😀 )

Thanks for the pictures. I have seen that before. I did not know you were talking about that particular one. That looks like 11"x11" per heatsink?
I think the heat sinks should be just right. As for Holcos I recommend http://www.percyaudio.com/ or maybe resurrected Part Connections called now http://www.partsconnexion.com/, although I didn't try them yet. Panasonic is obtainable from Digi-Key. I guess you are going to use their power resistors. They are pretty good.
