Welcome To THE ORRONOCO AUDIO DIY

Welcome to my blog.

A brief about myself, since I was a little kid. I often get caught by my parent dissemble their electronic stuff without their permission. From the simple torch light, a wireless telephone, and also their mini stereo system, I try to figure out on how they work. Of course I got punishment by doing that, but it is the pinnacle from me to start into this hobby.

Move forward to my junior high-school, I start making a simple electronic project that sell in a kit. This electronic kit can be assembly without soldering needed and they are variate from the simple flip-flop LED, a sirens sound, and a single transistor MW radio that operate using a 9 volt battery. At that time, this kit quite popular for beginner like me. They sell it on the books store and no wonder, in the 90's, the books store is one of popular shop. After some time I start to train myself to use the soldering iron, then I made a simple power supply as my first DIY electronic project.

From that time, my electronic project are expand based on PCB commercially available and I start to make an amplifier. I still remember how happy I am when my first amplifier start to work with just a simple speaker using a plastic cup as enclosure and a portable cassette player. From that, I start get into this hobby deeper and deeper.

This blog is made because my love to the audio stuff. I will shares, review, or post anything related to audio. This blog is my personal documentation about what I did on this audio project. You can use the contents in this blog as your DIY inspiration, or you can just treat this blog as an entertainment only.

The name ORRONOCO is has no meaning at all. It is just a name. It is across my mind when create this Blogger account.

The photo bellow is one of my DIY amplifier that I build without any PCB. Instead it is made by point-to-point for each components. The reason for this point-to-point built is has another story. I always waiting for commercial available PCB to make the electronic project. This has so much limitation such as the PCB size which always bigger than my expectation, the schematic and design that not suit to my preference, or I just want to build based my own design but I simply can't make any PCB. So one day I saw the internal of a vacuum tube amplifier that built based on this point-to-point connection. I asked myself, why I don't do the same for solid-state? This will be my new challenge to build something that I wish for without expecting from others design PCB. That's I think become my new journey to this new DIY audio world.

Back to this amplifier, it is a dual mono LM1875 Gainclone amplifier. It sound so good and it also look very beautiful. I made it several years ago and unfortunately the building process is not documented at that time. Hopefully with this blog, I will never missed to documenting the building process like this anymore.

  1. Hai Pak,
    Boleh share dimana belanja LM1875? Kabarnya sulit mencari yg asli yah? Thanks.

    1. Benar, kebanyakan sablonan dari IC TDA. Ke toko langganan saya saja pak di LTC lt.2 namanya tokonya O.K. Dia stock LM1875 peninggalan jaman dulu:)

  2. Apakah tokonya melayani kirim2 Pak? Saya tinggal di Lampung.
    Boleh saya lanjut di Google+ ya Pak.
    Thanks.

OPA1622 Vs. OPA627 High Performance Op-amps Comparison

This op-amps comparison topic is actually boring, but at the same time, many of us still curious about what others think about it. The reason is simply because of the op-amps variation are hundreds and they are depends by the implementation. The op-amps are considerably cheap and an interchangeable electronic components but they are not built for the same function. So in this discussion, I will focus on the modern Vs. vintage high performance op-amps in the simple non-inverting pre-amplifier gain stage.

Vintage Multibit R2R DAC Tier List

At the very beginning of this year, I committed to explore the best multi-bit R2R DAC. This is simply because I have plenty of the resources (from broken old unit CD player of course) and ability to build them up. If you think this kind a recycle from old un-used unit to become something useful, than I should stated myself giving contribute for greener world:) After all DAC that I built in this year, I think it is better for me to list them up again in one single page like this. Then I will rank them up in a simple tier list. The reason for this, so you all know what my opinion about of those vintage multibit R2R DAC especially in the sound quality.

TDA1543 DAC Review In 2021

It is a fine day and as usual I am reading and searching online contents related to almost anything I like. During my search, I stop to the few online forum discuss about a simple DAC using TDA1543 DAC IC. The discussion about this DAC was about 3 years ago, and the latest was about a year ago. Quite new and overall discussion about this DAC sound quality mostly are positive. It is interesting topic anyway especially I was built this TDA1543 DAC long time ago in 2016. At that time, I combine this DAC with Tripath amplifier  here  and  here  before it sold in 2019. That is also my first DIY DAC and I am quite enjoyed this DAC so much, at that time. The background story about this, previously I was using Sony Playstation SCPH-1002 as my reference CD Player. The reason I moved to this TDA1543 DAC is because the CD optic inside the Playstation is wear out and I cannot find the replacement for it. I pretty remember the sound quality of this TDA1543 DAC is quite comparable...
