JojoD, thanks for sharing that info, firsthand info based on your tinkerings with these kind of toys.
I still believe in the goodness of man
, not to resort to this kind of trickery. Sakura, already an established brand locally competing with Konzert amps would do better in performing an IQC before accepting this as a possible OEM product, I believe. The specs provided with these have always been inaccurate, im sure ,if you would perform a comprehensive laboratory measurements based on known Audio test standards.
How about the two big tubes behind acting as single diode (?), 2 can make you a full wave ckt.
Anyways, tubes connected with heaters only is a visual delight this Yuletide Season
.
As for the PMPO thing, this is a usual marketing gimmick then, especially employed during the peak of the Karaoke days (and until now).For all we know, dibay dibay lang ng certain factor, as per manufacturer's wishes. Could be dibay dibay by a factor of 20, 10 (?),usually, and also in this case.Thus 200WPMP0/ch as claimed, could just be 10W or 20W at 10% THD, in this particular case.
As for the tube replacements, pray
. Likewise, tube longevity is never a question, unless operated outside of its known parameters.I get old console tube amps (60"s), still with their original tubes and still working fine and yet to be replaced.
Para matapos na ang mga katanungan, sa mga nakabili na , baka gusto nyo buksan & take pictures so everybody here can do post mortem analysis and have idea ...kung mumurahin or pupurihin
