wala naman siguro mamemeke pa ng murang amp

[ATJr.]

speaking of murang amps, meron sa Electromark NOS in box pa, 2500 each....mukha namang hindi fake...

[tenorgasm]

Wala parin maka sagot if fake oh orig ang amp na ito. Sana me sumagot naman po sa tanon ko. Please

[pekspert]

Hindi yan fake. Why would anyone go through all the trouble of faking a super cheap amp? Mukha lang talagang fake ang mga konzert products kasi nga mumurahin ang materials.

[JojoD818]

mga masters, para saan yun pinagpapatungan ng toroidal transformer?

mukhang original naman sir may mga nakasulat na revision codes sa mga boards.

Can't read between the lines? Ok HINDI YAN FAKE.

baka platform lang master pandaya para pag sinilip mo from the top aakalain malaki toroid. parang gawa sa semento baka pampabigat na rin. daming workaround ng mga intsik sa products nila

[JojoD818]

baka platform lang master pandaya para pag sinilip mo from the top aakalain malaki toroid. parang gawsa sa semento baka pampabigat na rin. daming workaround ng mga intsik sa products nila

akala ko it's like a damping material o parang absorber or isolator nun toroidal...

At least totoo yung toroidal tranny diba. Yung iba kasi may malaking cylindrical shield on top of a small IE tranny.

meron akong nabaklas na chinese amp, plastic casing yan na me concrete sa loob, ginamit na dampening material para hindi magvibrate yung steell chassis pag nagsaturate or hevily loaded na yung torroid....me nagawa akong tube power amp na ganyan, nagbavibrate yung bottom plate, parang tansformer ng substation ang tunog....

ayun anti vibration pala ang gamit niya... nice nice... lagyan ko din ng mga concrete blocks yun mga amp ko...

[juanbote]

local and china made lang naman yan konzert. plus 1 ako dun sa kamurahan para piratahin yan.

[praktikal]

local and china made lang naman yan konzert. plus 1 ako dun sa kamurahan para piratahin yan.

meron talagang imitation o class A daw ang tawag. patunay na sa maliit na halaga ay pinapatos pa ng iba para lang kumita. kahit ba kumita lang ng 200/unit e kung daan daan naman ang maloloko...

[markcrenz]

ah ganun pala ang orig... may alikabok!

[bhenard]

dati akong gumamit nyan..wayback 1999,pambarog ko pamvocals sa studio practice.locally made,..indi po fake yan.ni-revise lang,dati kasi AV-502 lang,ngayon may "A" na

[jerix]

kakatawa kung me FAKE nga na Konzert amp. Sa mga naniniwala na me fake nga na KONZERT amp, ano ang tunog non? 

[JojoD818]

ang pagkakaalam ko, dati nagkaroon din ng local manufacturing nito dahil sobrang in demand siya sa mga videoke machines. palagay ko doon nag arise yun fake, pag made in china original pero pag locally made fake siya.

[ATJr.]

ayun anti vibration pala ang gamit niya... nice nice... lagyan ko din ng mga concrete blocks yun mga amp ko...

imbes na concrete, nakagamit na rin ako ng makapal na plexiglass, pwede rin plaster of paris, masakit sa kalooban kasi na gumamit ng concrete, di kaya ng powers ko yan....

[ATJr.]

At least totoo yung toroidal tranny diba. Yung iba kasi may malaking cylindrical shield on top of a small IE tranny.

meron akong gagawing IT's gamit yung cylidrical cans, powder coated naman at copper shielded sa loob....

kahit pa fake or original, iisa lang ang suma tutal, they suck.....

malabo yata makapag-manufacture dito nyan at that price point. malaking factor kaya mura yan eh mass produced and cheap labor sa china.

ayun na...

I'm talking assembly only, parang kinapos lang sila sa mga assembled units. Well that's the story from Solid, will ask again pag nagawi ako doon next time.

Kind of OT, but in the spirit of the topic, I think this is worth mentioning:

I wish I took innard pictures of my Yaqin Vk2100 back then when I had it almost a year ago. The inside was total trash compared to what they show on the net. My Vk2100 used laminated transformers (is that what you call it?) rather than toroidals shown on the net, and also utilized no-brand capacitors. With that being said, it still sounded great and sometimes preferred it over a Rotel 1520.

if that sounded great to you, then to me that is all that matters....it just proves that you can still enjoy the sounds even if no boutique parts were used....thank you for your testimonials....

what i mean is that as long as they can deliver what they promise in terms of performance specs, then that is fine....

Toroids are notorious for exhibiting mechanical vibration.  So you need to damp them.

thanks for the advice.
