STK4221 made by TONGYET ?? :o

B.I.G · 8th July 2004, 03:54 AM

I ordered myself a STK4221II for about 10euros but when it arrived surprise !!! IT is actualy a THK14221 c2-2 it has the TONGYET printing and for now it drives 3 ohm speakers from +/-29.5V rails measured in full load soo i think this is rather good .

Have any of you seen any TONGYET STK`s or should i say THK`s ??

DOES TONGYET really exist ??

PS: i have ordered a STK4050V-SAN and it was fake and it blew with 3 ohms on 50V rails . the top of it poped out really easy because it had no glue to hold it on

i have managed to get out 26V peak that`s about 18.5V RMS so about 114W rms in a 3 ohm load

PSU is +/-37V in full load

So is this a good fake or what ?

Same problem here, with an STK0050.
I’ll send it back straight away. With a little note

I asked for Sanyo!
