Hej..
Har skrevet tidligere angående opgradering af elektrolytter i min Acurus A250.. Men er blevet itvivl om min diodebro er kraftig nok..
Så efter lidt "google'ing" for søgen efter mere viden om modifikationer på A250'eren, faldt jeg over denne tråd på Diyaudio.com.. Fyren skriver:
"The first mod was done to the power supply; changed from the single bridge rectifiers to twin bridge rectifiers along with four new filter caps and bleed resistors. This amp uses a single 1000va 80v toroidal transformer with the filter caps wired in series and feeding the two amplifier board circuits. The +/- VDC outputs from the power supply filter caps to the amp boards is 45V. This mod was completed with no problems and improved the sound a bunch.
Next mod was to change the 1N5408 diodes to Fairchild Stealths, change input caps to MIT, the two input resistors, 2w resistors for the amp transistors, and wiring. This was also completed without any problems and also improved the sound a tad more."
Teknisk engelsk (inden for strøm) er ikke min spids kompetence, så er der nogen der kan forklare på dansk hvad han gør??
