Amplifier Kits

Kit building services - building high end preamp, integrated amplifier or power amplifier of your choices.

We have been approached several times and built kits of their choices, purchased from China or anywhere for several customers. They are interested at the kits sold in China but they have no means of DIY them due to technical capabilities. We came to the rescue, with the assistance to help them build the kits. 

Below is one a clone from China for about 1/20th of the price, for a very high end preamp - M7, priced over U$50,000

Let us know if you want us to build you other kits. Email us at the form on the left! 

We charge a fee for building, and measuring the kit before delivery. We do provide upgrade services too if they are not too happy with the clone kit stocked parts, with more high end parts like Duelund, Mundorf, Audionite UK electronics components. 

Note:
- We just provide building services. Customers can source the kits themselves, or seek our help to source the kits.
- Service charges are fixed. Do not negotiate, low ball or you will be ignored. 
- Vacuum tubes are either supplied from customers, or provided to us for measurement use.
- Power transformers are not part of the kit from China, and was sourced from J&K Audio Design. 
- Do not seek perfection on these kits. They are from China! We will try our best to perfect it but that's it.
- The stocked components may change anytime, depending on the vendor that distributes these kits.

Let's take a look at the actual built PCB of a very high end preamp - M7.

 

 

 

M7 schematic is posted by a lot of people in the internet. You can easily Google for it yourselves. We do not want to post it here. 

Below are the one of the kits built with much better components after a significant amount of money is spent on buying the parts. The upgrade is all worth it. The improvement over the sound is substantial!
