Customers love of our older units, rightly so we do too  - so we continue offering our renovation service for ONIX AUDIO 

Cherished products we made in the 80s & 90s  ( Classic is over 25 years old)  

Keeping them musically and functionally perfect WITH ORIGINAL ONIX AUDIO NEW PARTS 

We compare the finished renovation  to our reference original ONIX AUDIO amps . No one else can do this

​​

​​​​​

You get what you pay for in electronics less money mean less - Simple  ?  OA21 Amps are 30 years old 

They ALL need more than just a "Fix " our renovation takes 5  to  7 hrs - there is a reason why !

If one part has gone wrong, its a 100% certain something else will shortly follow, in particular when you take it apart to repair it 

We know how to take it apart, and in what order ,  and we know how to renovate all the parts ( See the Video Above ) 

We know the knobs are often glued on after having fallen off, we don't bodge as we don't need too. 

We have stock of parts other cant get/buy , and we make the parts you might need that others don't have - EVER.

​

We have never released the circuit diagrams or build parts list.

We made 1000s of Onix Audio Units, OA21 / OA20 / OA22  Etc yours was one of them

We renovate and restore , we re-make your amp  . NO ONE ELSE CAN or does DO THIS

​

We hear people say ... Parts don't matter ,  they are all the same !!

If you are ever told by a repair person parts don't matter in an audio world  .. NEVER USE THAT PERSON

​

They say  all amps are the same, so difference  do parts make ?

​

All amps are the same ? !  All cars are the same !  All houses are the same !  All Repairs are the same !

All sickness is the same , all buildings are the same ! all people are the same !!  ..YOU GET THE PICTURE

​

Run from the guys that think like this ?

​

Below  Explains WHY​​

​​

 Virtually without exception the parts we see in units returned to us  "Repaired" or "Upgraded  by " Audio Specialists  " in particular those posting on Social Media are just wrong  ..  They don't know what we did to make them sound so good, most "Specialists" know nothing about Audio but often claim they do. They just repeat audio enthusiasts  posting on forums things they have read elsewhere , 90% of the time its wrong .Upgrades are normally a specification detraction, and make our products worse , as they change the original sound, We have  never heard any upgrade improve it .​​

​

We often see products badly repaired by people that guess what's wrong. We have to rectify their mistakes before we start to renovate anything .  No one knows ( Because it is an art we did not share  )  they do not know what we did to make them sound so good  . Its unbelievable how bad some ONIX AUDIO OA21 amps have been bodged often with components that are actually dangerous and wrong.   * Wrong value,  wrong size , wrong type , wrong brand  even being glued in as they don't fit *

Repairers spray contact cleaner on switches or relays that are dirty ,  this ruins the components forever

( switches are often plastic and cleaner destroys the plastic after a few months )  . 

Older switches cannot be replaced , if we cant replace them we actually take them apart to renovate them .

We never spray contact cleaner on any amp.

If contact cleaner is sprayed on a switch, it will destroy the switch later, and many switches on our older units are no longer made .

We NEVER do this, that how we guarantee  our renovations for 2 years .

​

Our parts  are the RIGHT PARTS, We are the company that made the product we know what they require

We do this job the way it should be done, with new parts if required, they come back to you like new.  

All renovations are tested and "listened" too before becoming an ONIX Approved renovation , giving your amp 30+ years again.

We guarantee them for 2 years - Who else does this ?

COMPONENTS ARE NEVER CREATED EQUAL , neither are real engineers , cheap is always cheap, no one works for nothing.

The spec sheet cant listen,  but for your love of music and our older units we hope you listen to us .​ not others .​
