Thank you so much for the information about stk ic' s. I am using amplifiers stk series. Stk 4172, and 4152 old akkai and technic then Sony. Almost morethan thirty years.
I have built the IC in the year 1992. The ic was STK 459. I bought it from from Sansui's service center for Rs780/. The audio quality is beyond imagination. The number behind the IC is the batch/lots number is to check the authenticity of the hybrid module. The checking was done in the Sanyo's website then changed Matsushita Electric after Sanyo being acquired by the former. The dynamic range cannot be compared with any other IC of the same wattage at present. And this video took me to my childhood days. Thanks to the admin of this channel for the awesome audio masterpiece.
these were great for the time but these days a properly designed class ab should sound way better and more reliable. these are very sensitive to shorts and low impedance loads. only suitable for 8ohm loads.
@@mrpresidentatruevintageaud3128 I haven't seen this IC in decades. But I will check with my friends if they have old hi-fi systems that used this chip

Mit jane ke baad to kaafi mushkil hai.smps ka to pata chal jayega.aap uspar ampere meter laga kar load badate jaiye ,jaha par trip ho jayega wahi uska max ampere hai. Transformer me agar aap secondary wire ki gauge pata kar lete hai to fir uska maximum current bhi pata kar sakte hain. Jaise ki agar 18 AWG ka wire hai to current 16 amp hoga. Smps se car amplifier chala sakte hai. Jitne watts ka amplifier hai usse 20% jyada power ka smps use kijiye.
