2x30Vca înseamnă redresat şi filtrat +/-42V în gol. Prea mult ptr 7294 actuale, dacă aveai unele originale SGS din anii 90 era altă treabă. Foloseşte trafo cu 2x20Vca dacă are minim 300W, vei avea cam +/-28V, suficient cît să-l foloseşti şi cu sarcini de 4 ohmi, ptr detalii citeşte pdf-ul producătorului, nu reclamele fabricanţilor de chit...uri.

Sau 2x24Vca la minim 300w pentru sarcini de 8 ohmi.

Eu am folosit un kit cu acest tda alimentat cu un traf de 2x29vca si dupa avea 2x41vcc si mergea pe 8 ohm excelent kiar si cu forjari ,bineinteles racit cum trebuie.
