telefunken opus 6 rectifier

I had to replace the selenium rectifier in a Grundig and the B+ went up about 20 volts. But had to add a dropping resistor to make the FM rf amplifier work. It was very touchy. When the voltage was brought down to what the schematic showed, everything worked. BTW, the Grundig selenium rectifiers are encased in a flat metal case attached to the chassis.
