CAL alpha dac resistor values


Hello all,

im refurbishing my alpha dac. I can’t really tell what color bands resistors R112 and R122 have. Can anyone tell me what the values of these two resistors are?

Any help is greatly appreciated 

Thanks

The 18/48 version uses Cirrus Logic Crystal CS4328-KP 18-Bit Stereo D/A Converter (per a blog @ Twittering Machines).

I could not come up with the converter used in the 24/96 version.

There were 18 and 24 bit versions.

I think that your pic is the 18, but not certain.

If you can make out the processing chips that would be definitive.

I found a high res image on the web, looks like R102 is 22Ω (red, red, black) and R122 is 100Ω (brown, black, brown).

However, the color code was quite different from the image which @dekay provided in the first post.

Thanks DeKay,

I believe I have it figured out. I certainly appreciate your help. 
best regards

Sorry, I could not find a schematic and since my eyesight is not that great it's difficult for me to even make out the numbers.

I've used the Alpha and the less expensive model (Sigma?) in the past.

Still running an Icon MkII.

Thank you very much DeKay,

kinda hard to make out the colors for sure. Any chance you know the values are?

this is certainly helpful, so thank you. Maybe my tech can make them out better than I am able to. Very much appreciate the pic.

thank you.
