have vintageTechnics RS-D225W double cassette deck, which only has ribbon cable connector (no RCAs nor power supply in). It works fine, so would like to mainslead power it and connect to newer AMP by RCAs. Are there any adaptors anywhere or do I have to get the soldering iron out? in latter case: how do I avoid electrocuting the whole household, i.e. any circuit diagrammes somwehere?
