 ONIX AUDIO & OA21  - Q & A Classic SERVICE
use the  box to the right to ask anything

We will have to end this service in August 2025 so be quick -
It will end soon so be quick for this last offer  of  170 GBP all in .

It impossible to do the job properly for less than we charge , sadly some owners think you can so we have to keep picking up the pieces of bad work that has ruined our great  products , so the time has come to close our 25+ service in Aug 2025

 

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

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

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

We compare the finished renovation with sound to the original ONIX AUDIO amps . No one else has the ability do this

​​​​Fact is 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 !

 its a 100% certain something else will shortly follow,  its 30+  years old ,  when you take them apart to repair how often does something break or fail to undo ? 

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

We know the knobs are often glued on after having fallen off, or repaired by others .

We have a 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 list NO ONE ELSE HAS THESE 

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 " TV Repair " people say ... Parts don't matter ,  they are all the same !!

If you are ever told by a repair bod that parts don't matter in electronics   .. NEVER USE THAT PERSON

They say  all amps are the same, so what 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 ?

 

 

 

 

 

Parts are cheap for a reason - See above
