Can someone post the size of the power plug/jack? I bought the 220VAC version and need to pick up a 120VAC wall wart.
Just order a 120 vac 15 volt wall wart from JDS Labs (they also built O2 amps to the same specifications)
Just took a look at the JDS Labs website, listed for 99USD, Do you think that is a mistake or a placeholder since they don't have any in stock?
I just checked in the accessories menu and its advertized starting at 14.99$ (I guess for the US model YP-053) and 15.99$ for EU, Au amd HK models). There may be some mail charges but I doubt it adds up to 99$. I think they mispelled the price in the detailed menu beause all prices are x.99$ and the us is incorrectly listed at 99$ instead of 14.99$, missing the 14. ... if I recall I paid 14.99$ each for my two transformers bought last year from them to upgrade my Massdrop O2s. Maybe you should write them an e-mail or call them...
You may damage your O2 over time with a 20 volt transformer. At best your O2 internal circuits will overheat, at worse you will damage it over time overheating it (no instant blowup, but constant overheating will cause damage over time). You better stick with a 15 volt (or 12 volt) AC transformer in my opinion. I know all comparisons are lame, but I own a japanese version of the Technics SL1200 Mk2 turntable, which such version requires 100v AC input. As you know, north-american electricity standards are in the 115-120v range. The turntable would work plugged into 120v AC, but during a recent overhaul done on the turntable the technician told me the internal circuits and motor were overheating, and advized me to use a 120v to 100v voltage step down converter to protect the turntable over time, because otherwise its lifespan would be reduced because of the over-voltage causing overheat. I bought a step up/step down AC 120 to 100v converter and now the turntable doesn’t overheat. Now the O2 is not a turntable, doesn’t have a motor, but i suggest to use rules of prudence and stick with a transformer within the required specifications, which is 15 volt AC. The 12 volt transformer is or is not adequate to for the O2, I leave that to you, I took myself the opportunity to upgrade all my O2s with JDSLabs 15 volt transformers, but in the end a 12 volt transformer will at least not damage your O2 by over voltage. It may distort if you push it to its max capacity under a 12 volt transformer but you will not fry the amp that way. Best advice: if you decide to upgrade, stick with 15 volt AC transformers with the ones sold by JDSLabs.
Spec on my O2 calls for 14VAC - 20VAC. Seems like it's in spec.
12 seems a bit weak.
Well, never mind what I just said, John @ JDS just came back and told me to get a 12VAC - 16 VAC transformer.
