TDA1545A + output transformer?

[reaction]

Hello,

Just finished my non-os TDA1545A based DAC and I am obsessed by a new idea how to obtain a 'clean' capacitor-less signal path to my tube pre-amp.

Is it possible to use step-up output transformers like Sowter 8347 (1:18.7) or Lundahl LL1636 (1:20) to get rid of the coupling output capacitors and to win some passive voltage gain? Will these transformers work with TDA1545A?

I haven't seen any working TDA1545A + OPT project till now.

Thanks in advance!
