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.

Holy holiness, S/N 1???That's really cool to me. Thanks for your instruction and vids!!

Fascinating video, kudos to you sir.
Your knowledge of these and many other synthesisers, is second to none, and the fact you are willing to share this knowledge with others, through your videos, is admirable.
Keep up the great work.
Paul.

Synthchaser... *WOW!* ARP Explorer *HEAVEN!* I remember an Explorer demo at my Jr. College in 1975 by David Friend. I was impressed that the patches actually sounded like what they represented, (per the User Manual) and not just another cheesy organ stop! Thank you for the look back. (If only I could've afforded one, or a 2600 or an Odyssey at the time). #FlatBrokeStudent

You are using Deoxit D100L in the needle dispenser? Do you wait until the red carrier liquid evaporates before applying power?

[@synthesizerhome2041]

I own one! In Germany the ARP Explorer is very hard to find. Why was it namend Explorer I, since there never was a Explorer II ?

Can a bad Tanatalum capacitor cause damage to the other components on the PCB?
