firefox.. where can we find such carbide bits for the minidrill ?

ah...plenty of thread and articles about Non OverSampling....u can run a search in echoloft..there was a thread about it sometimes ago.. , i'm a believer in Non OS - DAC.. TDA1543. TDA1541A,..

mr Yeo of diyparadies has a simple non-OS kit that u might want to try....

http://www.diyparadise.com/dackit/dackit.html

hope that helps.

yes., this is an interesting amps. but quite difficult to find those low voltage tubes locally... ,

let us know if u able to source..., i'm interested on those low voltage tubes

very nice huangyong, can it drive passive speakers?

 

is there any simple tube headphone amp designs? is it possible to make a headphone amp with just 1 tube? i hav never try a tube amp before...know nuts about building one  but i'm game to try  is it going to blow up in my face if i get it wrong?

U can take a look on S.E.X....by Doc bottlehead...at their web bottlehead.com , this is a one tube experimenter set...that can work with headphones... and speakers... but that would be high-efficiency kind of speakers... 90dB and above....

if those imported goods declared value above 400$ then got to pay GST 5% of total purchase value...., and probably DHL/Fedex will charge u.. around $10 to clear custom.

I suppose so but i would advise u to have some sort of voltage protection in place and sum really good caps. Our main source voltage isnt exactly 'clean'.

may be we want to explore some articles on balance power;

eq; ,.

thanks man..., i'll check with frankie, last time i ask about carbon then he mention about his kiwame,...

Guys..... , any sources for Carbon Resistor locally ?,....like those allen -bradley..

by the way.. some funny pics...http://www.anothersite.co.uk/forum/viewtopic.php?p=55296

yap...Roberts runs the shop only by appointment..on Sat/ Sundays....

the guy had been in the DIY industies for more than 10 years....

i bought his copper OCC more than 20 metres...

my comment: very good for internal speaker wires.,

by the way : the silver occ that he sells is around 16~17bucks per/meter (if i can remember correctly),

if u guys plan a visit there , count me in.... and be prepared urself on the wonderful world

of "fullrange" speakers and low power tube gears .....

Hi Bram...., hi guys...,

sorry for not participating in da' forum lately.....

(hard times @ work ) ...not even touch audio for the past 3-4 weeks..

what I would suggest...perhaps... probably some gathering...

exchange words and some DIY guy can do a mod, then we can watch

how he handle the solder / components..etc...

U will be amazed , how much you can learn from watching ...and of course

asking question to the groups... how bout that

Guys.... , a friend forwarded me a link about CD-Pro2 Kit,

(description says, kit launched date...somewhere in Oct)

if u interested;........

...

well...it's a very subjective topics.. different people has different ears and perceive and prefer differently form one another... , wheter u can hear the difference , u have to try it by urself....

if u can't hear any differences...then "why spend the "megabucks" on it" ?

buying audio equipment is ...buying something that u can "hear & enjoy".... not because the audio-guru

says "he can HEAR it"

.......2228.....good pick Bram ...probably we should try it on 4D...,

who knows ... it can finance for more projects...

yap...the CD Rom controller and the DAC looks interesting...

I did read somewhere that diyzone no longer accepts order for

the CDPro kit....is it true ?

Well.., I've the honoured to audition it personally..., what I can say ..is...

'Very Nice Workmanship and well planed "

Bravo Bram...!!...

well..chokes cost money ...if u want to start small....u can still use tube rectification and RC filtering like what Digi recommends

Yap...Digi..., thats why we are interested on this tube project.....

what i wrote is just options to explore.... by this project we can start at minimum...and

keep on improving to push it;s limits...

Huanyong... u might want to look here..if u want to simulate the behaviour of tube rectifier...

http://www.duncanamps.com/psud2/

small notes, u might want to compare how an RC filtering and LC filtering circuits....

some people claims by using LC filtering u can gain some sounds improvement..

and probably u might want to look at an improved filaments supply by using regulated DC

for audio tubes......

great. tell us how it sounds...

2.Part no. 159414

12VA 2x12V (S$12.00 each)

Guys...this one is not working...the specs of trannies is 230V or 115V primary with

2x12V seconday..., meaning it is a step down trannies...in real life application, u wouldn't want to work it as a step up trannies... ..

How bout the 6x4 rectifier filament ?..

Why don we simpy use... One input primaary 230VAC...with multiples secondary output ?

lets say...165VAC.--150mA for the B+ ...and 6.3VAC 2 A for the filament to be connected in parallel ?

HuangYong...are u sure thats the right P/S diagram ?

I dont see any logic to get 0-18V to get unto input of the second trannies

(if u really wire it up correctly...on the second trannies...It will requires 24 V there)

Actually what we can do is to get a trannies that have multiples secondary....

( i can get it custom wind locally....)

by the way.....it's abit weird to get the filament wire up in series... (i dun get it)

well u got me excited here... ,

i would agreed that trannies and tubes doesnt need to be included.,

it'll kill us on the shipping cost... anyway..

Digi. how do u wire up the filaments ?

(paralled to all the tubes or different output from the trannies ? ?

Thanks all....,wow ..surprise here ...1 day without the forums...

alot had been done here....

yes..definetely this is the thing that i've been waiting for....

Digi and HuangYong.... how much will it cost to get the kit ?...
