Sony vFET Amplifier Part 2

Yeah, ok...
I was just guessing, because the majority of the
r-cores, that you find are from china

Anyway i need find good source to buy psu transformers ??
This from Antek are classic in diy projects for many folks
nice quality and price ( mecha noise or not noise i don't know ? )
but i understand it's interesting to try r-core if much better parameters
not only on specyfication data papers marketing reason to ask higher price ???
Mono block amplifier are less sensitive on magnetic field
but i don't like mechanical xformer buzzzz :scratch: 😀
 
I have used Toroidy from Poland with no buzz problems ever.

They have Audio grade transformers with isolation shield between windings and will produce custom transformers at very reasonable prices.

Thoroughly recommended.
 
Soundhappy: I have used about 20 Antek xformers and none of them have ever buzzed or hummed. BTW,
when are you going to post another audio comic strip? I hope you did not run out.

Fantastic to receive response from Diyer with good experience about Antek's.
Comic strip pictures ? Yes with pleasure that 😀
Thx and best regards

soundhappy,

toroidy seems to be the best recommendation for transformers in europe here in the forums. And the price is quite good as well!

I ordered a 600VA for a hotrodded F4 build, should be arriving soon and will give feedback!

Thanks MASantos yes i stay in tune for xformer news from you 🙂

My 400VA antek AS4218 transformer is dead silent.
I probably wouldn't risk getting an AN series one though some people have reported that they are noisy.
Stick with AS.

Cool 2PicoDumbs that mean we have few choices at resonable price and
appriopriate quality : Antek, Toroidy.PL and R-core from Selectronic.
R-cores are more pricey that others hope WalterW share us more informations
about how they work in his amplifiers :happy1:

ps. Probably 500 VA they are plenty ?
Let's say 400 VA is ok too so Toroidy.PL audio grade xformer price is 54 €

That magnetic shield band on the AS series is quite interesting and toroidy doesn't have that option. I remember seeing somewhere in the forum a member showing such a band to wrap around an existing transformer, but never found it again.

After Toroidy.PL parameters they have some too 🙂
Let's try all brands transformers :rofl:

Nobody used Talema here? It should be available in europe, i have always used this brand especially for ecapsulated model. Never have any any issue for mechanical or magnetical yet.

Hi Gadut

Encapsulated have strong quality construction i did not know this Talema brand i look more close on this one too.
Thanks for discovering 🙂

That's the screen between primary and secondary, not the outside magnetic band screening.

Anyhow, toroidy has quite a reputation and should perform very well!
Hi MASantos
I see steel can in ultimate hi-fi xformer version but it's cost more
again i stay in tune for news about your Toroidy xformers experience.
Thanks and have a nice day 🙂
