Continuing the visual tour is a side view on the 250VA power transformer…

… the AC filtering section…

… and the motorized Japanese potentiometer. In manual mode it's smoothly continuous, in remote-driven mode it steps in discrete increments even when that buttons remains pressed.

Here comes a closeup on the two big preamp capacitors, balance control at the far left, fuse holder in the middle…

… a view on the scaled-up capacitance banks for the output devices…

… and sundry microprocessor chips for various housekeeping duties and another fuse holder right next to the transformer.
