Option 4: https://www.amazon.com/Qaoquda-Adapter-Electrophonic-Olufsen-Quad-Stereo/dp/B07VHJ1CXT Either desolder everything and do a super-good job, or leave a sixty year old classic piece of gear alone, and purchase an adaptor cable. Both will leave you with the same result, as far as performance / sound quality goes. Don't half-arse it.
