The correct value,the how-to instructions and the resistors should have come with the dac as they did with mine.It is a matter of swapping one resistor only.Maybe some owners can share their resistors with you.I had Alpha for 5 years until it burned down.I threw away the manual with the resistors about a year ago.There are a lot of CAL dacs out there and i am sure you can get it all from one of the owners who does not need any adjustments.
Lowering output from my CAL dac
I have the Cal Alpha and the hi output from the unit plays havoc with the gain on my Modulus preamp. I understand I can swap out a few resistors to get the output down. Can anyone advise me as to the correct values and also can I put a multimeter on the rca outs from the unit to read output voltage or will it short something out? Also can I measure the resistance on those resistors while they are still soldered to the board? Carl
