Flatpicker, I like your idea! Yes to your question. The DC-servo op-amp and the C use whatever supply voltage is delivered to the card. November 21, The packaging does effect those things, maybe not drastically but it does. Flatpicker Member Tennessee Posts: But what is the potential of this unit?
Im a big api fan and so are lots of people here, but the stuff is hardly the holy grail. March 06, Started by tonymite The Lab. Started by eliya The Lab. Motorola LM11 Series Datasheets. Some have been discontinued. Thanks for chiming dtasheet with that info. All of these have extremely low DC offset and very low offset drift vs. That is a total mystery to me, if you are listening to the sound the things actually make. T DBX X?? API gear sounds cool, but so does a lot of other stuff.
I have called John Hardy in past many l1m1cn with MXP questions and also design concepts with the and other which he was very helpful. Of course the hardy thing might look cooler when you llm11cn done.
John Hardy Member Posts: It is one of the best forums ever, tons of information! Any response will be appreciated, Eliya Gwetta.
If you want the sound of the hardy with more flexability, you might consider also looking at the boards JLM audio has for sale, you can order two opamps from john hardy and use those with the JLM board which is wildly flexable for DIY, you can set it up transformerless, with transformers, datashet or without a servo, and would actually be easier to rack than the sony plug in as yuo would only need to drill holes could even use a hand drill to mount pots and switches instead of having to datasjeet out the block for the hardy frontpanel.
PDF and it works great? LM11CN Datasheet PDF Im the first person around here to set a spec sheet on fire and while the api stuff does sound cool and while I do use it on every project I do consistently, lm11cm is stuff that is just way cooler and much more robust.
Prior to that, the ADJ. In comparison, API is a very snobbish and unhelpful company who have bought and sold to many times and I wouldn? All things you need to weigh. I have used several op-amps for the DC-servo circuit. One thing I did was to add that extra trim pot for the DC-servo op-amp. We appreciate you sharing with us very much. March 11, Anyone made one of these? Thenm build your own. Does anyone else remember this? September 17, It seems that all I should do is build a power supply, input and output jacks, phase reverse switch, output transformer and supply a chasis it comes with a faceplate.
Thank you for your reply! I imagine that alone could change the sound xatasheet a bit. All of these op-amps have the ability to be further trimmed for the lowest DC offset by adding a trim pot between pins 8 and 1 with the wiper going to the positive supply. Same story if you wanted to build the circuit yourself.
