Dear Mrs:
I am a old surgeon from Santiago,Chile. Congratulations for your forum, I am a Tandberg´s collector.
I had buy a old Tandberg deck "MASTER UNIT,model TMU 502," and I can´t found it any link or reference.
It,s a big device with many buttons  with numbers 1 to 48...etc
Can you help me? Thanks in advance
