POWER amp upgrade
« on: March 30, 2008, 08:41:11 PM »
Hi there mga sirs.

newbie here.
I have a Konzert (K2) power amp w/ 200 watts/ch RMS @ 8ohms.
pwede pa kaya taasan ang wattage nito?
palitan ng parts or add some parts to increase the power?

Kung bibili kasi ako ng new amp, medyo tight sa budget. ???
baka may makatulong saken na pwedeng upgrade yun power.

thank you very much

bolshoi

Depende kung may pwesto ka pa s loob
Usually kasi yung ibang konzert ang pag kaka alam ko ay
wala na gaanong space, too tight inside, also madaming considerations
kung mag uupgrade ka. you need to change some resistors
and add power transistors, possible din to change the
supply voltage/current rating depende kung gaano kalakas ang gusto mo.
I've done it before pero sa ibang brand. Medyo nahirapan din ako.
Sana may schematic diagram ka para mas madali mo ma analyze yung circuit.

Pwede mo i-upgrade by Cascading another power transistor to increase the wattage, but you have to consider the following.
Pre amp driver, power supply rating, additional or separate heatsink for power transistors.
Check mo rin kung available ang schematics nyan.

depende yan sa design ng amplifier kaya mas mabuti sana kung may schematic diagram para madaling natin ma-analyze.

My innocent mind is struggling to find A glimpse of light
Broken, We are broken, we are burning inside

Open your eyes and look at me, I'm alone here
In the end it's just you and me,
In the end it's just you I see

Oh My body froze as I saw you fall
Pull me through this endless night

I agree with embedded and electron
I'm sure matutulungan ka din nila
pag may schematic diagram ka.
I will try to look for a schematic.
I will keep you posted pag meron.

ang alam ko may labas na ang Konzert na 500w RMS/channel.  Better and faster upgrade !

I'm a Konzert fanatic, just bought 600w speakers, mura na, reliable pa.

Thanks for the info sir.
OT.
i'm planning to buy 15" instrumental speakers also,
ano mas ok sa mga low end?
Konzert, Crown or Dai-ichi or baka meron pang ibang brand.

thanks

when it comes to Raon, who would you be recommending to acquire these Konzert amps.  Planning to buy one this month, I'll go for K-6.
