If you mean you read 73mV across the 1 ohm resistor, that seems either very high or a little low. It depends on whether you had both cathodes running through it or just one.
Good troubleshooting on the solution. As Jazz mentioned, the colors aren't always accurate. I don't know why transformer manufacturers seem so prone to this but I've even seen secondary taps incorrectly coded. Good thing they always get the red lead correct
And good job getting the customer to replace the filters (since he likes original). That's a biggie for a lot of amp collectors because new ones look nothing like the originals. Especially the big old can types. My reasoning with the customer is usually along the lines of "Well, the amp wasn't built with bad filter caps so your old broken ones aren't like it's suppose to be either." I hope you got him into a grounded AC cord.
