First of all, you need to be aware that this amplifier configuration is called 'The Widow Maker'.
The ac mains voltage is directly coupled to the rectifier.
There is not a transformer to supply the secondary voltages.
To work on and operate these safely you must have an isolation transformer that would separate the mains voltage from the amp (110-110Vac)
