As usual on this Sunday morning, I starting my day with simple exercise. I notice the sky are very clear with unusual cloud pattern, so I grab my phone and take a shoot. Then I think this photo will be suitable for this post cover.
Actually I already had some components to share. It is for the next DAC project and let's take a look.
This is the parts disassembly from old professional CD player. It is manufacture by TASCAM but I forget which type it is. I got it long time ago. The DAC board is using dual AD1865N. it is for balanced output which commonly use in professional audio system.
I cut the board and take only the DAC module. This PCB is dual layer with most ground plane are on the top. This is a top quality PCB and no wonder this is for the professional audio equipment.
Tascam using Panasonic Matsushita for the capacitors. Quite odd I never see Panasonic capacitors like this with the label AU. I familiar with Panasonic FC but not like this Panasonic AU with brown metallic and gold strip.
There is another components I need to share is this transformers from vintage hi-end Denon CD player. It is Denon DCD 3520 which have separate transformer for analog section and digital section. This transformer separation is a common implementation on almost hi-end CD player. The transformers are all covered with steel casing and resin filled to reduce the noise. The transformer condition I have here are in almost perfect condition.
That's all my shares, have a good Sunday everyone:)
