Re: Dual Class-A Line and Headphone Output Board Documents

Hi,
I see in the BOM in the first page:

8 Resistor, 470R 0.25W CF
2 Resistor, 4K7 0.25W CF
4 Resistor, 10R 0.25W CF

is CF means Carbon Film? And is that any problem if subtituted with metal film type?

Thank You.

Re: Trimmer in Pico, what and how to adjust

Hi Roger,
Thank You for the answer, I think I will get and learn rightmark analyzer first and ask You again later. And for the symetry, I should measure from pin 13 or from Pico output?

Thank You.

Trimmer in Pico, what and how to adjust

Hi,
I'm in the progress of building 2 mono pico as a selectable dual mono/stereo, there are 2 trimmer in the board, one is in RMS input and the other at symetry VCA. Could someone help me how to adjust those two trimmer and is there any notes when adjusting for dual mono and stereo mode?

Thank You.

Re: Dual Class-A Line and Headphone Output Board Documents

Hi,
I'd like to learn about this DCAO before I build, in the input, if I feed with unbalanced signal, can I just use I and G and skipped the 124X, R19, and R22?

Thank You.

Re: A Variable Width Circuit for The Precision MS Matrix

Hi Wayne,

Thank You, so I don't need to mess with another pot :D

OK maybe I should make another thread about Pico, I think that I will put FB mode for the MS mode using Pico.
