Potential Other Group Buys related to EUVLs F5X

[CeeVee]

it's the initial quote i got from them Patrick.

I know it's a good price, and for you only 15€ delivery !

 

[EUVL]

It is worth mentioning that you need 2 transformers for a stereo amplifier (2 channels).
So that would be for me €122+€15 delivery.

Also try to confirm if they can bifilar wind the 2 secondaries. If not, contact me by email.
I had developed another solution with Toroidy a few years back to overcome that.

Send Thomas my best regards.

PRP group buy ACTIVATED

The group buy for PRP resistors has been started and you will find the thread here. Please post any questions you might have there.
Cheers,
Nic

Tentative participant list for PRP resistors for EUVL F5X build:

Europe
NicMac 2 sets
Mravinsky 2 sets
APK 2 sets
Chalkandtalk 1 set
heinz1 2 sets
JBdV 2 sets
Ramallo 1 set
Studley 1 set
samoloko 1 set
CeeVee 2 sets

Asia
pmchoong 2 sets
Nikon1975 2 sets
qusp 1 set
wktk_smile 1 set
leejh 1 set
johnwmclean 1 set

USA
alazira 1 set
pchw 2 set
horio 2 set
Westley 2 sets
CanAm Man 1 set

Notes: This is a tentative list of members interested in a GB for PRP resistors for a EUVL F5X build (1 set = 1 complete F5X build (dual mono amps + PS)). The GB is run by NicMac, but was suggested by EUVL and kindly made possible by Fitzfish (see post #23). I will post more exact information on composition of a "set" (number and values), pricing and means of distribution/delivery when I have this information.

Will do Patrick,

I'll check, now with your 2 we are asking for 20 trafos ? is this right Gerhard ?.

Carlos

I have started a GB sheet please confirm your interest there ;

EUVL F5X "Toroidy" Tranformers Europe GB

Carlos

Yes, Carlos, that's correct; with Patrick's participation in this GB we are approaching twenty.

 

[EUVL]

I have changed the secondary voltage to 2x 16Vac.




Patrick

 

[EUVL]

I was asked by PM why I changed the secondary voltage to 16V.

In some countries, the mains supply can vary by some 10% from the 230V nominal.
Going 16V gets us the margin back in case it goes -10%.

In any case we can easily adjust the regulator output voltage, so there is nothing to worry whether 15V or 16V.

Carlos,

may I ask if I can put my name on the group buy sheet for the Toroidy transformers or is this group buy closed? I'm interested in 2 transformers.

I also use transformers from Toroidy (400VA) in my current F5X build and I'm really happy with the quality.

Regards, Uwe

 

[CeeVee]

Hu Uwe,

I'll put you down for 2.

I should have final data on this next week.

 

[smyslow]

Thanks a lot, CeeVee!

 

[Studley]

I am confirmed for 2 Toroidy(s)

Closing PRP resistor group buy

Dear all,
today I will be closing the group buy for PRP resistors for the EUVL F5X build.
The group buy thread is here.
Cheers,
Nic

 

[NicMac]

Among the components I still have to source for the EUVL F5X build, the power supply caps seems to be the most important remaining item.
Does anybody know the footprint, number, size and rating we should be looking for?
I think I read somewhere that the regulation chain is C-R-C-reg-C so I guess we will be looking for 6 caps in total. 25 or 35V rated?
Just some info needed for going shopping!
Cheers,
Nic

 

[heinz1]

Caps are standard 10mm pitch snap-in, max. 30mm diameter x 50mm height, 8 in total; according to:

http://www.diyaudio.com/forums/pass-labs/183362-f5x-euvl-approach-13.html#post2539692

There were some other discussions about PSU caps; I'll look further.

 

[Horio]

Hey Nic,

Here is a thread from a long time ago, regarding capacitors for the power supply.

PS Caps - Old Thread

You'll definitely want to check with Patrick or someone from the prototyping team, about the cap values. They may have changed since then.

 

[heinz1]

Thanks, Horio, that were the posts I had in mind.

BTW, @CeeVee:

Are there any news from Toroidy?
