NEED BIAIS ADJ. for JVC RX-R76BK RECEIVER

Look man, this is not rocket science.

How many channels the amp got, at least two right ? Just match the channel you fixed to the channel that still works.

Note that if bias is WAAAAAY off you probably have some other bad components. This needs to be dealt with before putting the unit back in service, otherwise it will be back.

If you got it fixed right, you match the bias cold then hot, then check it cold. If it's within 25% cold again then ship it. If not you're not done.
