Re: THAT1510 THAT1512 Single-Supply Preamp with "T-Bias"
I was just looking at the SSL 82E149 active mic preamp and noticed that it used T-bias: https://www.ka-electronics.com/images/jpg/SSL_82E149_T-Bias.jpg The full pdf is here: https://www.ka-electronics.com/images/SSL/ssl_drawings_index.htm I notice that the bias resistors form a ~3K differential load...

Symetrix 425 Manual
I had a Symetrix 425 expander/compressor/limiter in for repair and decided to scan the manual and host the pdf. https://www.ka-electronics.com/Images/pdf/Symetrix_425_Manual.pdf (25 MB) It uses a CA3046 transistor array as a detector with both log peak and log average outputs. It's very similar to t...

Re: THAT1510 THAT1512 Single-Supply Preamp with "T-Bias"
Thanks John - I do agree that 1Kx2 might be a little low as a differential load. 1.5Kx2 or 2Kx2 raises Zdiff to a more acceptable level. There is one source I need to cite that places the desired Zdiff around 3K total. I think the 3K assupmtion is based on paralleled active inputs for splits... I do...

THAT1510 THAT1512 Single-Supply Preamp with "T-Bias"
This single-supply preamp design was presented by THAT Corp. at the 125th AES convention as part of one of their seminars. It uses an input biasing arrangement we're now calling "T-bias." Although the circuit was designed for single-supply operation from 10-36V, the T-bias network can be u...

Re: Phono Preamps
Thanks John for the comments. I saw that inductor too and immediately thought of the JE-990.
