Technics SU-VX500 Amplifier Internal & Cleaning Process

I have been working at home since last Thursday, this is because of the corona virus pandemic that spread already. Stay safe everyone, stay at home.

Actually it is quite boring if not do something related to my hobby. So in this opportunity I pull out my old Technics amplifier from the cave. This amplifier is built around 1991, the model is SU-VX500. It is still made in Japan and the great things about this amplifier is the Class-AA patent technology that quite make this amplifier famous at that time.

So let see the inside and I will do a lot of cleaning to make this amplifier like new again.

Nichicon Super Through Capacitor Car Audio Installation (Part 2)

If you wondering where is the part 1 of this post, then you may check in the link here.

When we are talking about capacitor for car audio, one thing in mind is the big capacitor that mostly put at the trunk of the car, near the sub-woofer and the power amplifier. This capacitor is flashy and eye catching with digital volt indicator on it and few LED. But that's how it works for the sound pressure level improvement on their car audio power supply. That capacitor stored energy and release for instant demand need by the power amplifier and the sub-woofer.

But right now, I am not talking about that kind capacitor function. Just put away those capacitor first. I will focusing the capacitor for the car head unit. This capacitor must be good in specification, high quality rather than only high storage (Farad) capacity. This capacitor function is mostly to improve the power supply ripple rejection cause by the car alternator. The voltage go to the head unit will be much  cleaner.

Everything You Need To Know About Pioneer AVH-G115DVD

I got a request from one family member to install an audio-video entertainment in car. Hmn.. not a good idea for myself since I already satisfy with my current audio system here here and here. But I think I will do it. At least I should experience myself for having an AV head unit on car. It will also become a new review here too. So I did searching the suitable AV head unit to my car within my very low budget and end up to this Pioneer AVH-G115DVD. This head unit is very cheap, but don't compare to Chinese brand head unit, they are different class for sure. I got it for about US$100 brand new and this is what you should know about this cheap head unit which I believe no one will telling you about this.

The Sennheiser HD600 is an old product, you probably couldn't find the new one these days. As per information going around, this headphones is first release on 1997 and I am not sure why it is gone in the market right now. This HD600 is fortunately still can be obtain but in the second hand condition. The HD600 sound quality is the best said many reviewer. But is it? I have been using for a while the Massdrop Sennheiser HD6xx and I am really like it. You can find my review about the Sennheiser HD6xx in this post. Then how about the improvement this HD600 over the HD6xx? So I guess comparing the together will get the clear picture which one is the best.
