845 Bias Voltage

Posted by cawson@onetel.com (A) on March 6, 2015 at 10:17:38

I've just received a pair of new Pavane 845 valves and I'm installing them into my Consonance Cyber 845 mono-block power amps.

The amps have a Bias Voltage adjustment pot, but I've no idea what to set it to. I've mislaid the amp's instruction book too!

4.7 volts rings a bell, but if anyone could suggest what is best, I'd appreciate that. On testing the existing voltage with the original valves, I find it to be 4.5 ish, but I've not touched them for some years.

Incidentally these "Pavane" Hi-Fi valves appear structurally IDENTICAL to bog-standard Chinese Shuguang 845s except that the base is gold plated and the pins are a little longer.

I bought a pair of Shuguang 845Cs some while ago, but one arrived from China broken. These are structurally quite different and sound very good - although I can only test one channel! Can anyone suggest a supplier of these 845Cs, preferable in UK?

Thanks

Peter
