Resistance readings off [resolved]

Keep in mind that the L channel doesn't work even when the amp is not turned on! The tape out that I wired sends the R channel to my Crack, but not the L. All three inputs are the same.

Can you post photos of the selector switch and tape RCA jack wiring?

Bit of a mess, but here are some different angles.

The black wires on the selector switch are grounds.  The white wire is L+, the red wire is R+.  You have a black and white wire connected on your selector switch, which isn't right, so you need to swap that pair at the tape output to correct for that.

Ah, I see that. But will that also correct the other output?

What other output?  The one tape output channel that's wired correctly is working, the one that's wired backwards is shorting the output of the selector switch for that channel to ground.  When you correct that, you will make that channel work again.

OK. Great. I meant the output with green/blue wires. If this will fix that too, excellent. Thanks. I’ll report back.

It sings! Thanks. Sorry that adding this tape out introduced an extra troubleshooting step. I’m grateful for your help.

It really does sound wonderful. Bass seems to be more extended. The drive gives the music a nice kick.
