Oh really?.. I've seen many commercial amps with JP type pots and they're just as great sounding. Its quite true that Alps blue have a more accurate (because its logarithmic type) and heavier feel that makes one think the sound has improved a lot. I too can fall for that.
I sometimes wonder who is Alps biggest consumer of this item as I've only seen this very very rarely in commercial amps.

The Alps pots is not that heavy as compare to JP pots but it sure make a difference compare to those cheaper pots. I have an 10yrs++ Aura that is using Alps pots and it have never give me problem

The JP pots that I am using with the T-Amps and a few other amps sounds great.. will not change them for the time being

my unit is runing, my ear is so posion by multimedia speaker i cant get use to the highs at 1st,i hear no highs especialy im using a fullrange now....

i think t-amp will suits full range nicely as full range tents to loose out abit on the highs....

im getting use to it edi

listening to kiki dee concert which i copy from pcworks...........nice!!!

kiki dee?!! thats a good one!

I think its just a matter of pure luck as the pots I've bought from JP is always giving problem. I hate to buy spares as I've a bunch of other components left in the drawer and not being used. And for sure I will not bring a DMM to JP to buy parts

Since the T-amp is up and running now, its time to work on the casing..still thinking for the volume knob to use...

The casing seems to be the most difficult to source compared to all the other modding components...and I'm still stuck here. I absolutely refuse to start work on my TA2022 without acquiring a nice looking casing first.

I just got 1 of those alum casing from Nixie and plan to send it to be respray..maybe like Ipod bone white

nice, post the pic after respray.. gloss pearl white.. yummy..

or you can go anodized black... with 3mm diffused blue LED "on" indicator.

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"
