Re: ZM is spoking ...... (spikete spik)
OK - So, whole PSU made for relays not to be conected to any ground. Correct?Zen Mod said:
that means that any end of relay PSU isn't connected to audio gnd ;
in engineering words - relay psu is isolated from audio psu
Re: Re: ZM is spoking ...... (spikete spik)
we'll solve that minor issues tomorrow via skipi or phone ....
anyway - point is that you must have either dedicated winding for that 5V psu , or dedicated small xformer ; when you make ordinary PSU of that ( written in my previous post) , you just not connect it anywhere in system , meaning on audio psu ; they are galvanic isolated or whatever ......... two completely independent circuits .
diode across each relay coil ( wired in anti-phase (orientation) A to + side of coil) is for peak suppression ......... ya remember what induction is 😉 ......... how eeeny weeeny ceiling bulb can be responsible for melting contacts on wall switch .......
when that psu is isolated - it's completely irrelevant which pole you choose sending to selector switch

Simply that :
(Better switch 5V not GRd may be.)

spavleski said:relay, diode - clear http://www.kpsec.freeuk.com/components/relay.htm
first thing , when you decide to be engineer , you must learn ....... is - how to find information ........
well
you pass , this time, in Pass forum ........ where else ......

I hope that you bought few male (heiss) ones , for outputs ............
Yup, females IN, males Out...+ Unbalanced if possible somehow to wire them, too...Zen Mod said:

I told ya how ......... 1 & 2 from XLR to RCA ; when you use RCA , just plug shortie in XLR between 1 & 3
That's valid for both Input and Output connection - Correct?Zen Mod said:

spavleski said:That's valid for both Input and Output connection - Correct?
yup - for both , in and out .
it's always like this:
Pin 1 = Shield ground
Pin 2 = Positive balanced signal
Pin 3 = Negative balanced signal
you'll find tiny number near each pin on each good XLR of this world, so you can't miss ............. well - if you look 😉

imagine there is a razor inside the amp
Si, biensur.
You can trust a British company with a long track record to put the windings on properly.
Laminating core plates was a good find, the transformer companies have at least a solid 1/4 century experience with it, definitely no risc of mechanical transformer noise.
An output of twice 50Vac is a weeny much, but it does garanty that there's plenty juice left under load, only downside is the additional dissipation.
They're not as lavishly pretty as any of the Partridge PS/OP transformers of which i have a couple, way different league, but miles of difference in comparison to the majority of Asian manufacture.
(c'est dommage nous ne pouvons pas parler trop en Francais ici)
Razor reminds of Capitaine Philippe D'Arnot (Ian Holm, Greystoke)
Vous remain a singe.
Thanks for explanations.
Would you say that even for speaker filter application Trafokernspulen (Mundorf) would be better than Torobar coil?
Even shaved, a singe remains a singe?
Sure?
Oh lord I'am Tarzan? ....
Although I suspected that...

Don't know, the torobars weren't there yet last time i fiddled with dynamic loudspeakers.
Once ESL, twice shy.
En passant par hasard, oui, j'adore E.A.Poe Spot on
Wish i were able to translate like that.
Une personne pleine tragique
Yes Poe is one of my fave since first encounter (I think I was 12).
And recently again...
You certainly know that his french translator is nothing less than ... Baudelaire.
Strange coincidence.
Always found that good translations are kind of little miracle.

As Jacco point it out, because of my nice dagnall 2x50V tranny, it would be of advantage to have some volt loss before first reg in shunty (in order to avoid too much dissipation).
Which change concerning R21 to R24 would be fine/allowed for this purpose?
