DIY goodies

Received these 'goodies' in the form of toroid trannies and MUR860 diodes. Some are for the GainClone project and some are for a discrete 100W/Channel amp..

Thanks Gabanyayaya for bringing it over.. Will update on these projects later (much much later!) ;)

My third turntable, the Technics SL-5

Currently this is my main player. 1st/main turntable, the Dunlop Systemdek has been out of action for some years due to the deteriorated tonearm, an Audio Technica At1100. Have not found a suitable tonearm replacement just yet. Got my second TT, a Pioneer semiauto DirectDrive that has been active till I got the SL-5 some years back. Has been 'collecting' dust for sometime until I completed the VSPS(Very Simple Phono Stage), curious about how the SL-5 would sound,after a stylus replacement, connected it to the VSPS and I am NOT going to disconnect it for now! Will post the review soon.

Some info about the SL-5:

Direct-Drive Fully Automatic Turntable System with Linear tracking tonearm (1982-83)

Description
Type: Fully automatic
Drive system: Direct drive
Speeds: 33.33 and 45rpm
Wow and flutter: less than 0.05%
Absolute speed error: +0.1%
Rumble: better than -75dB
Tonearm: Low mass linear tracking

Review
The wow and flutter of the Technics SL-5 was very low and the speeds accurate despite the absence of quartz lock. Shock was fairly well handled which is normal for a linear tracker, and it also behaved well on the feedback test. Well constructed and adjusted, the lid mounted tonearm possessed very good geometry and a low effective mass of around 3g - £119 HiFi Choice 1983

2009 UPDATE!

Happy New Year 2009! :D
It is not too late I hope as It's still january!
Yeah I know.. I have been busy and not updating the blog as frequent and as much as I want to..
excuses, excuses.. hehehe..

Anyway,the T-Amp has been completed and I have moved on to other projects..
An STK hybrid amp, VSPS project and GainClone. Only the GainClone is yet to be completed.. waiting for some parts and time to finish it proper but I am taking my sweet time as I am currently enjoying the STK amp, with my newly completed VSPS phono preamp and my Technics SL-5 with a spanking new stylus that I bought from Singapore. LP/vinyl playing is much much more satisfying than CDs... Ooops I also did make a CD transport from a CDROM mechanism.. ;) More on this later..

Have fun guys! I know I am! :D

The T-AMp Project. Bi-Amping

After so many years in HiFi world,I will be taking the path to bi-amping. I made such a decision as the project made it 'affordable' and I have a pair of a very good quality speaker cables in hand. BTW, bi-amping is having separate amplifiers to drive (separately), the woofers and tweeters.. Major improvements to the final audio quality.. Let's hope so! Hehe..

Shown here is the back panel of my T-Amp casing, clearly showing the 8 speaker binding posts!

The normal red/black will be configured to drive the woofers, while the green/blue ones will be connected to the tweeters.

The T-Amp Project. New skills.

In the quests of fine tuning the T-Amp, I managed to DIY a toroid inductors to replace the existing inductors.. I use a 'ferrite ring'. The final ultimate inductor would be the air core type which I will be working next. Here's the coil in action!

New amp in the making: TA2024, T-Amp

Pictures updates:

An almost completed D'T-Amp.
Supposed to be bi-amp capable but don't have enough hardwares to install the second board.
Now a 'normal' stereo power amplifier driven by the superb Yamaha 'pre-amp' :D

Enjoy...

New found technology: Tripath T-Amp, TA2024

May be slightly late but I stumbled the above while surfing the trade sections of LYN. Someone wanted to sell a brand new Sonic Impact's T-Amp for roughly RM300 ( I think). Further googling and surfing a Lowyatter selling a T-Amp boardfor a mere RM55.. I ordered two..

Currently in the upgrade/mod/burn in session.. The recommended 100 hrs is a long way to go...

Will update this with some pix soon...
