hi, anyone have build amp using sunken 2SA1216/2SC2922. i am searching for circuit design using this transistor. pls hlp me.

thank you.

of korean INTER M amplifiers were equiped with that outs..... nice devices

never liked interm amplifiers though

whats your expected out ???

hi, my uncle had a kenwood amp and i saw it was used 12pcs 2sc2922 transistor. i want to use this transistor to make one for my uncle. i never tried this. i know it is very old.

is there any web i can find circuit design for this?

thank you.

that you canibalazied the kenwood amplifier and now you are full of transistors ????

oooo what a pity ....i keep these amps alive ....

any way just tell us a few more like what trafo you have and what is your power requirements

The Elektor Ulti Amp uses the Sanken 2SA1216/2SC2922

Elektor's "Ulti Amp"

hi, today i tried on sysasim 5_3 amp using power transistor 2SA1216 and 2SC2922 it works but only gets too hot. do you think i can use this transistor on symasim amp? what else need to chnage?

thank you.

thank you.

Did you check and adjust idle currnt after changing the transistors? Did you sheck if there is any oscillation in the output?

hi ilimzn, thank you. here is the sysasim design and i made change on only power transistor with 2sc2922 and 2sa1216. i dont know is there need to change resistor too. need help.
