The Man in the Iron Helmet

Congratulation with Daft Punk, who won 4 GRAMMY Awards 2014 nomination.
Album of the Year | Record of the Year | 
Best Pop Duo/Group Performance | Best Dance/Electronic Album
From awesome cool album " Random Access Memories " 
These guys are real man who keep their costume concept until now 
also their child too.
I really love this album especially " Giorgio by Moroder " 
that remind me to listen " Stop the Rock " from Apollo 440 again.
Both songs are full of entertainment emotion and so excite every time to listen.

Monday Modify : Modification of Sony TTS-2500 (PS-2250) turntable Part I

From forum in Lenco Heaven 
Many suggestions from this Sony deck's owners.






After having seen schematic of TTS-2500, 
I just replace almost electrolytic capacitors with new and reliable caps, also variable resistors.

Before ...

... After


Replace diodes of motor drive circuit and make new main power supply board using switching modules.




This deck came with faulty neon bulb, so I've modified by using blue LED instead.






Next process just making new heavy wood plinth ;)
