Re: Gentle persuasion over time

I have a neighbor who has the reverse situation trying to save the tree that looks like it is going to fall onto his house. It's tethered to a larger tree using tow straps. This happened in 2010 when we had a wet winter - saturated ground - and then got lots of ice and snow. A lot of trees just fell...

FET front end with 600 ohm drive capability now off the shelf.
None currently available are probably good enough for a distortion analyser front-end without some external bootstrapping to reduce CM distortion.

Looks like Amber took Siliconix advice and used this in the 3501 front-end: https://proaudiodesignforum.com/images/jpg/Amber_Analyzer_Composite_Op_Amp.JPG Amber 3501 Front End Using the Siliconix Composite Op Amp Topology. Note that the 5543's inputs are grounded and the compensation terminals are u...

Re: Flat Balanced Input Moving Coil Phono Preamp Construction Information

I have three PTS boards to build today. An MM pre, a MC pre and an RIAA-EQ. I had sold out of my assembled ones. I've been putting it off because the weather has been beautiful and just gotten cooler. I think I'm going to build all three at one time doing all the sockets in one pass, resistors in a ...

Re: New: A Direct-Coupled Input-Capacitorless Active Mic Preamp

I would guess it would allow for large enough a correction, but it would need less attenuation at the output of the servo opamps, thus potentially adding more unwanted stuff to the signal. I intend to find out. I really like the ZTX851 MC front end and with mods I think it will make an excellent mi...
