bro,
Maybe you're right; there is no C21 on our board just like other parts purposely omitted at its design stage.
I will go home and look at my T-amp but since sifu already said no, I doubt I could find it.

The term 'sifu' is widely used and not meant to belittle anyone but referring to folks who have more intimate knowledge than others on the subject matter; at least that is my own interpretation. 

I thought so too during the ordering stage and reason why I have omitted them earlier.

Those capacitors in pF range are actually used for filtering on our T-amp board but their actual measurement do not comform to specification stated, moreover since I have almost all the discreet components, I might as well buy six more pieces which should cost me less than RM10 to have a T-amp with full discreet components.

Just toying with the idea, reason why I added a proviso of ... if I don't damage the board prematurely to be on realistic side.

haha bro, i was joking, but im taking th mundurf off...

i tried without the input cap, when i 1st on the thing there is no sound   luckily it is bcos i didnt plug in the RCA 

without input cap =
1: loud!!! it is louder, duno whether it is bcos the mundurf takes lots of power tho...
2: dynamic and bass, now those drum from japan are sounding really nice!
3: details! easily heard
4: air! it sounded spacious
5: abit harsh now and brighter, mayb mundurf did a great job at making smooth..

guys my op-amp sitll fine gona do the tweeter amp as well....and put in proper 20k resistor....but now with the caps taken away, the frequency cut off thing is not applicable anymore?

So, the input caps is purely a DC blocking cap function?
BTW xtorm, can you check the DC voltage at the input? I did.. you'd be surprised.. 

guys scrap the idea of removing input cap for now, i just try with 20k resistor there is distortion, with 12k there is none, but in both situation the speaker is being push out! even during idle. sorry didnt notice tht previously....but yesterday i play it loud for 30 minutes without issue tho...

i just burn 1 of my mids with 20k resistor .... should i move to lower resistor value and try again? hmm.....

yes ongbs there is the 'tub' noise when i on the amplifier, at the same time as the mid being push out...gona get another mid tomolo....so sad.

my PSU is a simple hit-n-go solution:
Transformer 12-0-12V 1A rating, LM7805, 100uF, 10uF, 1N4007 x 2

That's all. Basically a simple regulated 12VDC power supply circuit with a full wave rectification. I don't have digital camera so abit hard to take pictures for sharing.

No idea. Got them from Jalan Pasar at RM1.50 each! 

who are you looking for, xtorm?

FAKE Elna!..but usable lah!.

Hello all, juz wanna ask is the T-Amp only suitable for driving speaker?

bro, u buy the F-Elna from which shop?

Oh, I get from this shop call calor in Ipoh.

OMRON relay mainly for what?

is it the same relay we use for signal lamp for instance?

Jazzy,
Yes, I was there from 4 to 6.30pm, went there to pick up some parts for my second T-amp which I will start to remove the caps and SMDs shortly. It wasn't raining when I reached there.

I tested the new T-amp board; it has the 'pop' sound even in stocked form whereas my well run-in unit which I replaced the caps with Vishay ERO 2.2uF and Panasonic 1000uF 16V surprisingly has no 'pop' sound.  I am surprised hearing the 'pop' sound.

This thread is the fastest growing thread ever here in audiophile, top poster, yc, gabanyaya, ongbs, xtorm and jazzy

ongbs,
no updates from you?

ongbs,
indeed looks like a war zone!  , your home minister not at 'war' with you, ah?

Mine is on the contrary.. This morning was still a mess especially the dinner table as I was making the speaker relay board. Later in the afternoon under the request (more like an order!:P)of the home minister I had to put away all DIY stuffs out of sight till Hari Raya is over... 

Looks like this week very very minimal DIY if there is any in the first place!

Keep this place alive guys..! Orang luar negeri tak cuti Raya! Hahahaha!:lol:

ongbs,
Oh ya.. I forgot about your 'toy' He's not 'toying' around with your T-Amp, no?

Anyway, my T-Amp mod is almost maxed out.. Other than installing another board for bi-amping there would be no major modding anticipated.

Well here it is an almost completed T-Amp playing/singing right now in my setup with the cover removed..

Hohoho...bro ongbs you just bought a 3-way crossovers for bi-amping!!!!!! Is it an electronic x-over just like the Linkwitz-Riley filter?
Is this some kinda universal x-over suitable for all speakers???????

I'm very very keen to know man......            

ongbs,
can provide details later on? I am sure some of us are interested. I know gaganyayaya is..
