I’ve got 3 broken ARP Explorer I synthesizers, and I show you my approach to repairing and restoring them. The ARP Explorer I (Model 2900) was ARP’s first non-preset single oscillator synthesizer, pre-dating the Axxe and the Solus. It includes the same 4027-1 Voltage Controlled Oscillator module found in the ARP 2600, and the same 4034 Moog Ladder Filter Voltage Controlled Filter module found in the ARP Pro Soloist.
