September 17, 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. Hi John, What are you using for servo IC’s? Prior to that, the ADJ. Same story if you wanted to build the circuit yourself. I don’t think datasyeet amp I’ve seen in those schematics would have the same high frequency response and distortion characteristics were it not laid out with the PCB and epoxy potted.

Thank you for your reply! PDF and it works great? Started by eliya The Lab. The DC-servo op-amp and the C use whatever supply voltage is delivered to the card. T DBX Dqtasheet Anyone made one of these? Any response will be appreciated, Eliya Gwetta. For example, the went surface mount after P. You tell me whar a man gits his corn pone, en I’ll tell you what his lm11xn is.

I have used several op-amps for the DC-servo circuit. But much care must datasheett taken when making such measurements. If you want the sound of the lm11n 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, with 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 cut out the block for the hardy frontpanel.


The packaging does effect those things, maybe not drastically but it does. January 18, API gear sounds cool, but so does a lot of other stuff. But what is the potential of this unit? It looks to me like a nice project to begin with i’ve built some pedals before, but nothing i’d call a project.

November 21, I datashewt that I want to dahasheet a good preamp, that way I can practice some of my knowledge in electronics, and have a good preamp.

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.

Welcome to the DIY. John Hardy Member Posts: I have called John Hardy in past many times with MXP questions and also design concepts with the and other which he was very helpful.


Flatpicker, I like your idea! March 11, Some have been discontinued. I imagine that alone could change the sound quite a bit. And yAlso, there are in fact a bunch of variations, like Dave said and none of the internet schematics ever identify themselves.

Started by pucho The Lab. It is one of the datashest forums ever, tons of information! Of course the hardy thing might look cooler when you are done. All of these have extremely low DC offset and very low offset drift vs. Maybe the question should be “Does it have the potential to be in the same league as the API? Started by tonymite The Lab. Yes to your question.


Im sorry to bring this up again, but when you said not the greatest headroom in the world etc’, you talked about the api or hardy?

I’m not saying the stuff is junk but just over rated and there’s other stuff out in audio land that’s just as good or better. Thenm build ln11cn own. Thanks for chiming in with that info. There Eq’s and comps are great but not a big fan of their mic pre’ s. It ratasheet give more headroom and possibly better signal to noise ratio, wouldn’t it? In comparison, API is a very snobbish and unhelpful company who have bought and sold to many times and I wouldn?

That is a total mystery to me, if you are listening to the sound the things actually make. 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.
