Vintage 8 track tape echo- Diamond D-77 echo chamber- tape delay repair, refurbishment, demo 

We go through a 1978 Diamond Electric D-77. Open it, inspect, clean, test and demo. It is a long one and I really get babbling so feel free to skip through. Check out Vintage audio nagoya on reverbreverb.com/sho... for this item and many more cool echos, pedals, amps etc. from Ace tone, Roland, elk, Boss, Kastam, Teac etc. and [@vintageaudionagoya on instagram for many more pics and demos. Ask any questions you may have.
