[Review] JDS Labs Objective2 Amp - Page 4

post #46 of 51

Well, it will actually not stop charging at all, just the current when charging is so low, that batteries will never fail because of that. It's exactly like a car battery: if charged on the car will not overload, but if charged on dedicated powerful charger may blow away if left more than 12-16 hours. :)

 

So, no worries to overcharge O2. ;)

Hello all. I have been thinking on making myself an Objective 2 but when I went through that list of parts given out for its design some of them are discontinued or on backorder. So I started to wonder if their is a more updated list of parts for this device that is more current and maybe even some upgrades and such. Does anyone have an info on this?

 

And Yes I know I can just buy a Kit with all the parts but I kind of like buying such parts from my usual supplier. Plus if I do build this O2 I will be getting the PCB and Enclosure from JDS Labs but as for the rest of it I was going to order it elsewhere along with parts for a few other devices. I sort of wanted to add it all into one big order.

 

Anyways any info on if their is an updated list of parts would be appreciated. Thanks :)

There are many companies still building the O2 amp, mostly because it's great neutral and power sound, but also because of the price and DIY kits.

 

You can find original parts if you look harder or maybe better, try reading http://www.agdraudio.com/Page13.html for substitutes.

 

Cheers!

Only the power jack has been discontinued. The O2 PCB was updated in 2013 to accept common 2.1x5.5mm barrel jacks, such as CUI p/n PJ-002A.

 

The original Bill of Materials contains suitable alternatives for other items.

This is good to know as well. Thank you. :)

Can the popping sound damage the headphones? It inevitably happened to me about 3 times but no more than 5 seconds. Just paranoid.
