Sir, gusto ko sana malaman difference with or without 4th constant. malaki ba audible difference?
ano power supply ginamit mo, ss o tube rectified?
maraming salamat po!
In my simple words, yun walang 4th constant medyo matalas, and to some materials, sibilant din. Yun meron naman sir, mas controlled yun highs, parang mas clearer sya at may definition. Di marunong magsinungaling, pag panigt plaka pangit din tunog.
I used ss rectifiers (UF4007) only with a B+ = 385VDC, as always, paramount filtering is a must. Duncan's PSU designer helped a lot in this department. I was supposed to have regulated the phono psu with a Mosfet pero di na push thru sir.
Sana tube rectifier naman pag ikaw na nag try.
