RE: Or... It's the high quality Chinese transformers

Posted by megasat16 on April 13, 2017 at 20:58:01:

Well, I have measured 100+ transformers (OPT, IT, Input) and never came across the transformer that can do 20Hz at -1dB with 15KHz HF bandwidth at -1 or +1dB. At HF, usually transformers got more efficient and I am sure you knew that.

Anyway, a very few pairs of the Chinese PP OPT Transformers I come across used in (raysonic, grant fidelity rita) and the line output transformer used in the Twin Audio 6SN7 preamp measured quite well with -1dB from 20Hz-20KHz.

Build quality or how they run wires or the other parts are not on par with their transformers is the nonensical statement.

Contact the LM and find out why their spec at 15KHz bandwidth. I still think a typo somewhere.
