Bybee Music Rails Problem - Page 3

shoulda dropped the Bybee name if they didn't want the reputation

Well I checked out the Bybee Labs website (distinct from Bybee Technologies of "quantum slipstream purifiers" fame) and I must say it was total truth in advertising. The label on the Bybee Rail clearly stated "Bybee 2A POS"...you can't get anymore truthful than that.

Yeah there is fools enough in the world. In fact a lot of them on Hifi forums. But the Bybee purifier I am sceptical to. I think some Carbon Composite resistors do the same job.

Not many is in this to solve my problems. If not keep out.

Erlend, you are correct, the Bybee purifier and the Bybee Music Rail are completely different devices. One is based on physics, the other based on enlightened engineering.
I have a pair of the Music Rails following my HP Lab power supplies. It drops the measured noise about 20 dB.
Having access to the schematic, I can tell you that it is just electronic engineering, inside, however, IF you for any reason, put too much voltage across the device, perhaps 60V, it will probably break, and cannot be easily repaired.

From what I have read they don't like capacitance across their output either; or at least some capacitance values will cause problems.

correct I did mistakenly think you were talking about their other similarly dubiously named device. a power supply smoothing device that doesnt like capacitance across the output? if its so sensitive to surrounding components, they should make the schematic or at least some of it, public. maybe then people wouldnt lump it in with the other snakeoil they sell, which has been fairly thoroughly examined and deemed to not change the world as we know it

A very common characteristic of feedback regulators...the information about this is included in its data sheet much as it is with IC reg's.

I think the 2x 47 uf and 100 nf. I have after the Bybee should be ok ? Before the Bybee I have 1000 uf. 44 ohm serie 33000 uf. 12 ohm serie 10000 uf 33 uf and 100 nf.

The aplications says :less then 100 nf or more then 33 uf. Maybe the 2x47 uf. is to far away 7,5 cm.

Maybee that diode was bad from the start . I will try with another .

Erlend Sæterdal · 16th November 2012, 08:55 AM

Ok I tried with another mono amp . It looked alright up to ca 30 V . Then suddenly the voltage dropped 15 V.

Want my money back.
