Grundig Powered Speakers Repair - 1961

Описание: Two Grundig Powered Speakers from 1961 blowing fuses and getting way too hot. They are also designed to operate from a 220 Volt power supply and need to run on about 240 Volts. I will have to change a few things around to make them work. I cannot find any info on this exact model but found a circuit for a similar model, "Grundig Stereo Verstärker Box IV\V" which I think is the previous model with a single speaker.

My Digital Signal Generator:
The Signal Generator is a project kit from a local electronics magazine called Silicon Chip, there is a sister publication in the UK called Practical Electronics, it was featured in the April 2018 edition but mine has a oscilloscope function as well which I don't use. There may be a later edition in PE with that feature.
