achhi information D aap ne .... mere paas bhi 2 IC pade hai... 1 to bilkul naya tha jo chala hi nahin, phir maine 7294 bnaya, vo powerful hai...or easy bhi hai..
I have one of the Stk amplifier and it is working. It gives 200w out and I got it from jank yard. And it only cost me 10rs. When I checked it it was working properly and I am using it with my sab woofer. It needs 24v.
very informative video sir, I have made STK4141 -II audio amplifier some years back , sound quality bahut achha tha, lekin abhi mujhe lagta hai 2sc5200 me banana chahiye
maine old stock 2sc5200 original japan (non ttc) wala use kiya p3a amp main,2sc5200 voices ko aage laata hai,aur snare drums ko peche dalta hai,isse songs ki musicality kam ho jaati hai,tda7294 full neutral hai,equal voices aur equal snare drums deta hai.Sabse baap,musical sound(hi-fidelity sound)-philips,sanyo,matsushita,mitsubishi ke integrated circuits dete hai,jo abhi manufacture nahi hote.(ye ics voices ko normal rakhte hain aur snare drums ko aage laate hai,jo actual musical hi-fidelity sound balance hai.)

Very useful details of STK i.c. you have given.In my experience, failure rate of this i.c. was high.In earley 90's decades,many japanis audio companies were using STK. but witin 6 or 8 months, these i.c.s replaced by myself.After all coustemers not satisfied.
I have always replaced the stk power packs with discrete amp boards. It's much more reliable and even if something goes wrong u can easily fix it. U don't have to replace the whole thing.
