Question about RCA DRC8335
My unit is showing 14.7v on DU83. That's getting too close to the 16v limit on that cap. RU83 in this one is 1K ohm.

Guest and Lesfix. RU83 located on the DRC8335 VCR PCB is a 51ohm 1/4 watt 5% tolerence resistor, color coded green-brown-black-gold. As to zener diode DU83, I haven't been able to determine it's value yet but am working on the problem.
Be aware when either or both these components fry, this indicates you need to replace the following two overheating capacitors on the power-supply board, which were directly resonsibile for knocking them out:
• C216 1000µf 16 volt (upgrade to 35 volts)
• C218 1000µf 10 volt (upgrade to 35 volts)
Could you email me regarding this problem when you have time. Mention Fixya and DU83 in the subject line so I realize it's from you. Thanks. firstname.lastname@example.org
