An audio project?

Just undertook, well kinda agree to help MDZ to restore an antique phone. Restore as in making it 'useable' again...
Not much of a problem as telephone apparatus is purely 'electrical' stuffs,especially really old phone.. hahaha..
Plan A would be trying to make it work with existing 'electronics'.. which is just a handful of wires and coils, solenoids(for the bell ringer) if these fails, chances are they would considering the age.. will have to go with plan B..
Old antique phone on the outside, latest technology on the inside.. hehe. Will try to make or use the original bell ringer.. would be weird an antique phone with an electronic ringer..

Maybe JTA(JazzTech Audio) should venture into audio stuffs restoration works.. question is, ada demand ka? or worth the effort and/or returns?

Finally, I have finished the earlier mentioned pre-amp. More like

a prototype here. Built a casing for it from what I had in the 'store'..

Will need to improve on this. It's a passive preamp anyway ;)


Whaddaya know! The repair on the MA R252 turned out fine!

no more rubbing/chafing noises!

Have been playing/experimenting with some simple

pre-amp circuits.. finally close to midnite, eureka! got the

circuit right! Playing with D'Bomb right now.. may need some

tweaking tomorrow.. the basis for D'Bomb II and GainClone..

Take a look..

LM3886-Gainclone Amp

I have read this for quite awhile and curious about it's sonic performance. Some of the makers have but great praise for it's sonic performance against it's costs... I'm sold! I gotta try it myself!
You can google for gainclone and read it for yourself! There's even a gainclone webring.

Will be busy with this for awhile.. hehehe..

I am planning to build my gain clone into this casing.. which was bought by a friend in Bangkok, an over kill but what the heck!

This is pending it's sonic evaluation against TheBomb, BombII and my reference Technics SU-A900 MK2 integrated amp...

Oops!, have to build the BombII first! Damn, so many things to do, not enough time ler..

What you think? ;)

2008 Update! In April! Hehe

Whoa 4 months have passed and this is the first

update this year! Ah well.. better late than never, right?


The Det'nator still with my 'friend' for perspex panel manufacturing and mounting hole drilling. Why so long? He's doing it in his own time, beside his hectic day schedules... so don't wanna push him. Will call him tonite, to check on the progress or (non-progress :P) My apologies to 'gby'( ze customer)


Just got back from Jalan Pasar..
bought some stuffs for my GainClone Amp and
'pre-amp' parts for the Det'nator and the GC.


Also had to 'repair' my Monitor Audio R252
as there is some 'rubbing noises' which I found
that the voice coil is chafing against the magnet.BTW, this is unfinished work, ok!
