Respected Members,
Restoring my Opus 55 TS the new magical eye illuminates lightly. The B + is 40 volt low the normal value. The Selenium rectifier is very old and I replaced its contained with four silicon diodes 1N4007 forming a bridge with four 4.7 nf capacitors in parallel to each diode. To adjust the B+ value I put a 220 ohms 10 watts resistors in series with the power transformer. Now the B + is in normal value and the EM80 glow well.
But during the first and half minute, after power on the radio, the B + rises to 340-360 volts and slowly reaches the normal value. I understand that is a characteristic of the Silicon rectifiers and not in the selenium rectifiers.
This abrupt increase of voltage can be dangerous for other components of the radio as power capacitors, output transformer or output valves? It is necessary to control this abrupt increase of tension?
Thanks in advance,
Bruno.
