TT upgrade update

Whew! Finally, I'd consider it completed! Only cosmetic touch up to be done.
Basically the plinth has been reinforced, the OEM signal cable has been replaced with a pair of output RCA sockets for which I can properly use an 'audio quality' RCA cable to connect to the amp(phono) input.
Whats left? Isolation 'feet' to be installed. Couldn't decide to use rubber or metallic cone.. will have to do some serious auditioning at night if there would be any differences at all!
Last night initial listening I do detect a more solid imaging to the sound stage.. how much does this 'mod' cost me? Few ringgit! The only costly thing that I bought to complete the work is a portable/battery operated multispeed drill..
Now that my TT is given a new 'life' I am itching to build a phono(RIAA) preamp. A module that would complement the D'Bomb or the Det'nator...
Sorry folks no pics at this point of time, will update later. Now can concentrate on the Det'nator (GBY's) and D'Phone (MDZ's) hehehe..
Have a great weekend guys! I know I would.. ;)

Minor Project -TT upgrade update..

Have almost completed the plinth 'cosmetic job' after acquiring a specialised glue made for jointing wood. Found out the SELLEY's one is 50% much more expensive that another brand that I got (from Jalan Pasar). No nails/screw was required. After the 'glue' cured, it was as solid as nailed job!

One last bit to do is to replace the output cable. Plan to install a set of RCA sockets so that I can use an audio grade RCA signal cable to feed a good 'phono preamp"<--- this one coming up next, after finishing/completing a long queue of other stuffs to complete. One of them is GBY's Det'nator, then MDZ's jurassic phone. Hahahaha.

Next update with pictures....

Minor Project - My TT 'upgrade'..


Have been putting this for quite a while but finally have a little 'bit' time to do the above.
Need to change the signal cable, this will definitely improve the sound as the built-in cable have aged.. and need to reinforced the plinth too, and to isolate the whole TT from external sound/vibrations...

More of this later... click the photolink for more pics...

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?

update-preamp

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 ;)

updates!



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? ;)
