@moshe tes!
You asked for a ready-made fee.
Universal subtractor-amplifier board for
DSD4497, DSD4497DUAL, DSD4499.
This board has been tested to maximize
possible results.
I can sell several ready-made boards to those who can supply it. The board will be built on one stereo amplifier!
All the necessary information for connection is on the board.
To anyone interested, please contact my personal mail.
I assume from your statement, you are not interesting in selling a single unit? Also what is your personal email?
If by any chance you happen to accept single orders, is it possible to just get the board(s) with recommended part numbers for parts? I already have a few AD797 and LME49600.
