Hello, Does anyone know what the bridge rectifier used in the Onix OA21 is? I want to replace mine since the transformer is making a vibrating type of noise its a 'BRRRR" sound that comes on every 30 seconds r so and Im trying to see if I replace the rectifier it might improve on the noise. I...

Let me know how goes. What works for me is leaving it on all the time or at least on days when I'm home and I know Im going to be listening it it.

I just plugged my Mulimeter into the mains and tested for DC and just sat there staring at voltmeter and waited for the noise to occur. When its every 30 seconds its much easier. The noise is very common when its first turned on. Like today I left it on for 14hrs and no noise after the initial...

I tried doing turning off all and every appliance at the same time. What’s odd is if I leave it on, it doesn’t make that same sound. I use to leave it on all the time. Sometimes for days on end and come home put a record on and it was flawless. Then I started turning it off and for the first few...

I have a spare 4/11 somewhere I would be willing to toss your way free of charge depending where you're located.

Not sure if this is the right place to post this but here goes. I have a Onix Oa21E and I am experiencing some noise from the transformer. Its intermittent and sounds more like a "brrrrr" sound rather than a buzzing. It can be heard from 5 feet away. It does not translate to the speakers...

Anyone out there know the Voltage measurement on the BC337 transistor on the phono amp of the Onix A-21. I measure the following Collector=21.6v Base=21.6v Emitter 0v Not sure what could be causing the emitter to measure 0v? I'm not getting any sound. Thanks

sorry to revive this old thread, but can you email me the final schematic for the onix oa-21 phono board to [email protected] Thanks

Hello, Anyone out there know the part number for the transistor I believe its a NPN transistor on the Onix 21E phono board. Mine is shorted. It begins with BC3xx. I know its a motorola part, Im guessing its either a BC337 or BC327. and are these interchangeable? Thanks in advance

Are you referring to a capacitor? Not sure what board you have but mine has the following caps: 2 47uf/25v 2 100uf/25v 5 10uf/25v

LOL..

I have seen a few photos of the PCB. The round canister and the slim line, both appear straight forward and should not be too difficult to overhaul. I would imagine the caps at this stage of its life are probably exhausted and they should be replaced if its to continue seeing use. I don't have a...

Gaius, Thanks, very helpful. Although have been somewhat surprised how many people have had laser issues with it. I'm thinking that it may not be the laser at all, but perhaps the caps in the PSU causing laser glitches.

I know that the Linn Karik is getting long in the tooth, but I have a chance to get a Karik III and understand that they sound quite good. My concern is: How reliable are they? Do they have issues reading scratched disc's? Are they sensitive to vibrations? My current player is quite...

Bass with the Klipsch is amazing. wish I had 12in stands as they rumble a bit with the hardwood floors when driven past 12 o'clock . But very happy with them They also sound different than the Harbeth. The Harbeth being 84db are also very easy to drive as they are 8ohm stable. But the Klipsch...
