2270 in the house, and it's baaaaaaaad

Tell me about switching out the shaft on your switch. Did you just accidentally clock one of the wafers out of synch? Can you pull the shaft back out and clock the offending wafer to its correct position?
 
I have another 2270 in for service and I did some detailed comparing of the selector switches on both. The selector switch on my 2270 has three wafers (the rotary part) wrong and two correct. I will start working on it soon. Not gonna be fun though.
 
You have my sympathy. I had a dial cord pop this afternoon on a 2270. I had seen the lump in the cord where maybe someone had glued it together before. I had treated the front end bearing points and was running the dial back and forth to work it in. I'm not looking forward to replacing it but would rather do that than do rotary switch surgery!
 
The selector switch on my 2270 has three wafers (the rotary part) wrong and two correct.
The selector switch shaft should have two flat spots so each of the 5 wafers are either right or wrong (as you noted). To align the two wafers, you would need to remove the shaft then rotate the misaligned wafers 180 degrees then reinsert the shaft. If the 2270 is like other models, the schematic will show the wafers contacts in the CCW selector switch position (AM) so if you select this, the wipers should look exactly like the schematic (assuming no error in the schematic).
 
OK, I managed to get the source selector switch sorted out. All inputs are fine, except the tape input. Tape is dead on the right channel no matter what I do. It is fine on the left but if I touch a wire underneath the tape switches then it cuts in and out. I am guessing I broke or pinched a wire somewhere while I was doing the source selector stuff.
 
Ok, I found two broken wires but I honestly think I broke them while I was pulling out the switch at now. I fixed those.

What is happening now is I have no left channel in any source normally, but if I push the “hi blend” knob in then I get both channels. Seriously.
