Which one did you get? I went there early last month to get one, but they had sold out the RM28 one. I picked up the almost all the other parts....RCA sockets & the binding posts (I got really slimfit ones! ), white and blue LEDs, the famous jp volume pots - they have plenty of both linear and log types, you have to `debate' with them on the use of these before buying or they'll just give you the linear ones.

So I only need to order the Vishay/ERO MKT 1813 2.2uF 63V caps from Farnell, and it's just the casing that's missing.

cyl1000, please show us the pics after the respraying. I might copy you.

yes usually pots have A or B curves, linear, log etc. even JP ones, not limited to alps/nidec etc..

also another parameter for choosing pots is the size, like 12mm ,16mm and 20, 24mm etc that controls the power handling..

my setup update
hmm sound certainly improve with some support on the speaker...better low end extension, seems better soundstage too, more highs too....amazing wat simple things can do


vocal is really thick and nice, but not for action movie tho...lags ommm....haha

Thought of anodized but hard to get a good job done..send to a shop at sunway before but they just did a "chin chai" job. As for power LED, thought of getting a circular LED light pipe to put around the volume knob. So far, no luck yet from Farnell, RS or Futurlec . I will have to get these parts ready before I can proceed to drill and then spray.

Added on December 28, 2008, 6:26 pmI got the big casing measuring 253x167x87. Hmm...what do you mean by the slimfit RCA n binding post? Have you tested the pots? Which shop you buy from? One of my friend JP pot is failing Have to help him get a temporary pot.

BTW, anyone can help to source for a circular LED light pipe???

hey cyl1000 got my pm?

collect when you come to my office again?

how does your circular LED light pipe look like?

you need LED or not? I got lots.. SMD white, blue etc..

Sorry..forget to reply I will go to your office on Tuesday/Wednesday bout noon..maybe collect from you then..thanks.

If you look at those midi hifi, some have lights illuminating form the volume knob (Y.C. JVC micro have it). I have attached a picture from another thread..looks something like this.


Attached thumbnail(s)

thanks for the pic, maybe the inner knob holder (to clip and hold to the pot's fluted or geared shaft) is made of transparent plastic material? and can be used to act as "light guide"

I am also looking for a casing for my t-amp with extended board plus power supply module. I think that will be as big as an astro box. I got a spoiled VCR player some where in the store room, maybe that will ok to use.

After 10 hour of listening, the t-amp smoothen up a lot, hissing sound also less. I saw somewhere mentioned new capacitors need 160hours to run in. That sound really a lot for normal listening.

kww ill meet u up on wedsnesday same place ss2 starbucks

t-amp need 100hours of burn in time according to alot of sifu.

ok cyl1000, see you then, hopefully im in the office.

loving my fullrange + tamp...hehe

Added on December 29, 2008, 9:13 pmjust compare mundurf and octave 2.2uf 100v dc, but mundurf boad is with elna audio grade 1000uf chip supply cap

mundurf better, wider and more body to it, more bass extension too...

I can't wait and have started on the casing. I have drill most of the holes for the RCA, volume control, speaker binding..for power switch, thinking to use round (push in to ON) or rectangular (push up/down). For the volume knob with LED, I've got a big knob from an old donor amp (Denon) and most probably drill 4 holes in casing but hide inside the knob. Use VR to adjust the LED brightness and hopefully will get the effect.

wah use VR to adjust the LED brightness? so when you turn it will have variable brightness?

VR as in voltage regulator?
3V is what u need depending in LED types and the brightness that u want...

variable resistor aka Pot kua.. but not sure it'll work cos LEDs are current source devices ...

pot would not work proper..
I have tried that!
a variable voltage regulator, may be .. a 0 to 5V would be 'workable'.. with the necessary current limiting resistor, that is!

hee...hee...I'd not want to construct a voltage regulator for a few LEDs I will just use a variable resistor to do the job.. might not be easy to get the desired brightness but I think will be sufficient...

Added on December 30, 2008, 6:28 pmJazzy is right that it will not work proper..just for me it is "proper" enough for my application..

Just got the Tocos pot (VR ) from one of the bulk order...damn..these pots are really mini..

Added on December 30, 2008, 6:32 pmTook out some pots from an old Denon amp with 250K and I think will be sufficient to dim the LEDs. Got some big transformers with shielding but the voltage is too high for t-amp..

I have installed a white small LED inside/underneath the knob of my volume/pot knob to get a similar effect.. nothing to see in the day but looks 'cool' at night..
After much experimenting I found a 25K series resistor to be suitable with an input voltage of 9V. 20K is already too bright!
My preamp is a 9V battery powered, lass for a month for daily usage.. not too bad.

Oh, the preamp is driving my T-Amp power amp.

How high is 'too high'?

if you fellas want blue and white LEDs let me know.. give you free la.. got so much in the drawers...
