Default Re: Regentone A133 HT smoothing capacitors, V4 cathode resistor

Hi John,

It's possible that the replacement was done by a professional repair shop, and marking the connections was just something they did. Mine don't have red marks. The shop may also have "upgraded" to 50uf as they may have believed it "increased performance". I myself am usually dubious to change off of manufacturer's specs, as the circuit was designed by engineers. Jerry made some great points as well.

Cheers Geoff
