Hi Colin.I am a friend of "sonix" .Are you familiar with excellent Wega amplifiers?Have a great collection for example :Wega 3120,3131(youger sister of 3135),3141 .Have seven.Extremely good powerfull amplifiers and tuners section.Well built,clean assembled.Like tanks.Anyway after 40 years have problem with poor quality of plastic parts(like almost all great brands) ,indicators(burnt) and stereo decoders.Wega was "captured" for a short period by Sony but I prefer older receivers.They also produced legendary Aiwa minitower model 22 (I have too) but design was far away from beautifull Aiwa.
Models: tuners,amplifiers,receivers,TT and cassette decks.
Regards Tom
PS In Poland is much easier collect German vintage.
Have bought 2 days ago wonderful and rare cassette receiver Nordmende 8500 SC.Excellent in design,powerfull(70 W music.wonderfull sound and good tuner.Cassette deck also very good.In the night hours unforgetable.
