My TDL's RTL3 is rated at 90dB/W/m. With T-Amp connected I wonder why some people need 100W/channel or even more to play music? laugh.gif

hahah i mention to him many times it is not enough biggrin.gif if you need a 1-amp adapter let me know bro, it is only as big as the regular adapter, rm2x if i remember correctly. im sure it will improve things as t-amp depends alot on the supply too

but im grad u mooded it and like it smile.gif

the input cap must go, jalan pasar rm2 3.3uf is better then it, well tht shows how "good" china stuff are, so i dont really fancy those "enlarge" board with so call hifi grade caps in it selling in china, rather get it done here with stuff from farnell or RS.

Yep! It was there before end of last year. They actually have a 'demo' unit. What do you think of the price?
It came with a toroid, and the toroid alone costs RM300! shocking.gif

At 30x the price of our DIY unit..... sweat.gif sweat.gif sweat.gif

OK lah, maybe after adding the cost of the toroid, the tube preamp stage, the casing, miscellaneous parts, trouble shooting, + assembly labour, not too bad.

Did you manage to take a peek under the skirt bonnet or get an audition?

I certainly did! tongue.gif Not entire impressed by the sound though.. the connected speakers were not well positioned..

My verdict? I can do better with my own DIY and stuffs and at a fraction of that cost! laugh.gif

jazzy bro, don't judge them by your high standards lah. biggrin.gif mesti kasi chance sikit, ya?

Anyways, hmm.gif did one of you guys build it for them ah?

BTW I finally bought one casing for my T-amp. Same as the one you use for your VSPS, jazzy. Next, to order the Vishay caps from Farnell.....or has someone got some alternative spares to get rid of? I think I will start tinkering with my kit sometime between now and end of the year. biggrin.gif

Hey March,
If you're going to order any parts from Farnell, can tumpang some small capacitors. Few bucks barang only. Let you know later if you're keen.

That's wot I told me wife too.....don't order no more root beer! Get the real stuff! biggrin.gif

BTW, I need some recommendation for a reliable digital multimeter....budget below RM200. High time I get a real DIYer's meter instead of using those cheap RM20 JP `Sunwa' discards. Maybe I will order from Farnell also lah.

march,
There's a few TENMA models sub RM200 that should be able to suit your budget.. wink.gif I do not know how 'reliable' this TENMA is..
I can only vouch for FLUKE as this is used extensively in the aviation industry and boy, they were made to lasts! thumbup.gif

Thanks, jazzy bro. I will keep an eye out for TENMA...but this name isn't very familiar to me. Where to get? JP?

FLUKE is way out of my league (or is it the other way round?). I don't wanna look like an engineer, since engineer I'm not.

Oh gosh, I just saw Farnell's prices for digital multimeters....vomit blood.

I'm looking for something easy to read (need big display fonts for this old man), reads usual stuff like DC & AC voltage, current, resistance, capacitance, accurate to 2 decimals,.......warm sound, solid mid-range, powerful bass, sweet treble, got PRAT, etc.

TENMA is available from Farnell. I saw one 'cute' one at RM44. wink.gif
Oh yeah.. the pricing there you'll vomit everything la! Hahahaha!

Actually there's one low end DMM from SANWA I saw on offer the other day in JP.. Forgot the model number.. I think bsl is having the same model.. SANWA is okay with you?

Heyyy, are we talking about DMM here? rclxub.gif

This is not bad for RM200.74! Can stretch 74sen? laugh.gif

Oops sorry my mind wandered off again....was thinking of the type of sound I want from the T-amp after modding lah. Strange, I'm doing that (mind wandering, I mean) a lot nowadays..do you think it's Alzheimer's I'm contacting?

OK back to the DMMs...what the ****, my searches for digital multimeter on Farnell keeps showing up GOSSEN METRAWATT @ RM8XX. They're trying to squeeze me ah? How come you can find TENMA but I cannot? Ayoyo!

Sanwa is okay....still got a genuine 20 year old analog Sanwa in my toolkit. But finding it very difficult to read the thin needle, especially in low light. DMM is only the way to go.

Anyways, lessee...TENMA - 72-7735, RM200.74....seventy four sen can lah won't break my bank. Specs well within my requirements...great, shortlisted!!!
