Sowter transformer 8347 I/V stage fot TDA1543

[sharpi31]

I too am very interested in trying a transformer coupled passive output stage on my single tda1543 dac.

Can anyone suggest a suitable sowter transformer and I/V resistor value?

Thanks in advance 🙂

so im in this situation as well.

i've found just this, designer of my russian TDA1543 DAC suggests connecting through 10uf cap, like pictured. it looks like big caps are needed. what i dont understand is all those connected-together wires on the right side..

thanks for opinions

EDIT - i overlooked this thread is about different Sowter model, i have 4383

Referring back to earlier parts of this thread, will the TDA1543 work with a DC short on its output? It seems to me a coupling capacitor is required, as shown in post 22.

I am using 8 pcs of TDA1543 . . .

With eight x TDA1543, you don't need a transformer - Google DDDAC and see Doede's write-up on the circuit which, though it only has only a resistor as I/V stage, works pretty well.

will the TDA1543 work with a DC short on its output?

Not for long.
