Zenith T724 Selenium rectifier
#2

Yes, the anode goes to the (-) side and the cathode (end with the stripe) goes to the + side. 

You will probably need to increase the size of the dropping resistor.  You can measure the B+ voltage and substitute higher values of resistance until it reads what it should (probably between 100 - 200 ohms).  To be safe I'd use a 2 - 5 watt resistor.
