Maybe the question should be “Does it have the potential to be in the same league as the API? Hi John, What are you using for servo IC’s? 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?

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. January 18, They are also very slow op-amps trade-offsbut they don’t need speed because they are dealing with extremely low frequency signals only. March 06, Started by tonymite The Lab.

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.


As for the ‘s, they do work well with 24V and sound great. 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?

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? It would give more headroom and possibly better signal to noise ratio, wouldn’t it? I don’t think the 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.


Started datzsheet pucho The Lab. 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.

I’m not saying the stuff datasheey junk but just over rated and there’s other stuff out in audio land that’s just as good or better. March 11, Anyone made one of these? You tell me whar a man gits his corn pone, en I’ll tell you what his ‘pinions is. Thenm build your own. Does anyone else remember this? There Eq’s and comps are great but not a big fan of their mic pre’ s. 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!


Welcome to the DIY. 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.
