Default Sugden A 48 Mark III

I need bias information about this amplifier . There is plenty of misleading info on the internet and plenty of confusion about the model and this one is the Mark III version

Thanks
Kind regards
Sakis

In between i was emailing Sugden directly and a nice fellow Patrick response in my email .

His information was that this Sugden is single rail with 4700/63 per ch in the psu and 10.000 /35 in the output and it should be biased at 360ma over each fuse for each ch .

I will not argue with Sugden but isnt that a bit on the risky side for only 2 transistors TO3P per amplifier ...I was just wondering

Kind regards
Sakis

Single rail with 63 volt caps. So a max voltage of around 30 volts across each output. That's only 11 watts per device.
