Anyone know a NEC K821 Replacement?
 

Working on a Mobile Authority 120ZX. It has 4 of the NEC K812 for the power supply that need replacement.

I checked NEC and they say it's obsolete. Suggestions?

Thanks

Hi,

Try 2SK1296 or 2SK1291 - if they are available there.

Cheers,

Thanks. Mcminone has the 2SK1296. Off on another ordering spree :D

Checked in my other substitute pocketbook and that says 2SK1296 too ;)
So I'm sure that will works!

Regards,

Back to working on this amp; I just got in the parts.

It's working now, but the 2 right channels are not as loud as the 2 left channels. Why would this be?

Thanks

Is the bias of OP devices readjusted yet?

I'm sorta new to this, so some more explanation is needed... Are you talking about the pots in each channel of the outputs?

If so, how do I properly adjust them? I've attached an image so you can see the output stage of this amp.

P.S. In case it's needed for this, I do have a good scope...
