Hi,
Here is link for DIY Club DAC board :
http://www.diyclub.biz/catalog/prod...d=266&osCsid=b286a0e30c5552d3ffaf633073142421
How to calculate the output transformer primary and current.
Board has 8 TDA1543 in parallel.
I have read that minimum load for TDA1543 is a 10K.
10K / 8 = 1.25K.
Now I have few pairs of UTC A-43 which can be configured
at 2.4K/600R for parafeed use.
OK here be a step-down 2:1 but maybe worth for no oamp
and just one possible high quality signal cap.
To avoid the cap how I calculate primary current ?
Each TDA1543 has 2.3mA so 8 x 2.3 = 18.4mA.
Well maybe a small interstage and get no cap and no oamp.
Please make a opinion.
I feel that is too easy to be true :>(((
