+/-36VDC sa ispravljaca,5600uF po grani :) 

Unitrin trafo izvadjen iz nekog uredjaja,oko 200VA,2x24V :D 

Iako je manji trafo nego sto bi valjalo,ne greje se i ne zuji,ima veliko jezgro,sto je ekstra :P

Ovo ti je vrlo bitno, zanavek, u diyaudiu generalno. Star ground iliti jedinstvena tačka mase.

Da ne bruji, zuji, čvrlja, mulja, itd...

 

Baš nedavno nađoh sliku kako je to Rotel u nekom ampu uradio, kao po udžbeniku:

Nije baš sve po PS-u, trebalo je bar raseći ploču oko konektora na elektrolitima, kada već nisu posebni vodovi urađeni - već jedinstvena ploča.

Aj?

I da ploča bude od 24-karatnog zlata.

Kompromisno i prihvatljivo resenje, i sto se ideje i sto se prostora tice.

Mogli su da odvoje mase leve i desne strane, pa da ih posebno spoje, da pregrupisu velike struje i izdvoje od sitnih iz ulaznog stepena, ili preampa..

A mogli su i da produze zemljovacu pored trafoa, a ne da vukljaju neuredne zice(istina kratkim putem) s kraja na kraj.

Niko ne garantuje da ce zemljani sum da ide bas tamo gde se zamislilo po ploci.

Ima dobrih, ima odlicnih i ima bahato dobrih resenja :)
