Palpakis!!! The seller backed out! Pagkatapos niya ako paghintayin ng pagkatagal-tagal eh wala din pala. The product (home-made-did-it-himself-project) suddenly had "technical problems" daw.
Ahm, questions:
1) I've seen the schematic for a CDRB20 and from the looks of it (and I agree it should have one) meron siyang isolation circuit to cleanly separate the signals from the aux and from the cd changer ... however the seller says his product doesn't have one... well he didn't exactly say that pero when I asked him (over the phone) where he bought the isolation chips, sabi niya wala ... and I was astonished kasi he probably made the module using solid state devices... pero hindi din daw (leading me to conclude that he didn't put in an isolation circuit)
2) Please lang po hehe saan po pwede makakuha murang CDRB20 please please :-D ... if yung sa-suggest nyo po is >3T hehe di ko na yun afford ;-)
