TAMA 305 - Schematics
Picture from http://www.cykong.com
This page is rough and dirty -> some folks from synth-diy mailling list asked for the schemoes.
The originals of these scans are copies, done bye a kind technician at Meinl, the distributor of Tama in Germany.
I scanned this with 300 dpi.
Chi Yan Kong provides some great modifications on his website: http://www.cykong.com/Synths/Tama%20TS-305/TamaTS305-MIDI.htm
