I have just completed the 15ips tape saturation emulation addition onto the pre-amp. The picture below shows the tape saturation circuitry and how it is integrated into the pre-amp. I have uploaded the samples on the sound cloud here: https://soundcloud.com/eugenenks/sets/sample-of-preamp The files are from BOZ Digital Lab mixing contest, I do not own those tracks. Please listen to the samples a few times because there might be glitches when the files are loading for playback

My second built is a 500 series microphone pre-amplifier. This is pre-amplifier use WIMA capacitors and THAT Corp. ICs. There is a second part of an optional pre-amplifier 'color' circuitry that can be added. I have the 15ips tape emulation circuitry which will be my next project. I will add some recording samples when I have the chance to do so. Here are some picture:

My 2017 resolution is to build all the gears I need. Instead of heading to a shop to buy what I need, I will buy kits and/or source for parts needed to build those gears! Without further ado, I would like to introduce my first DIY project, the passive DI box. It took me about 30mins to put it together. If you have advance understanding in electronics, you will realize that you can start changing some of the components to change the characteristic of the DI. I will put up some
