The Sound board needed new caps installed as you could only just hear it , even at full volume, Jaycar had most of the caps that were needed. Installed all new caps into both boards ( Bar two in one board , but i have the correct ones to go in now) , A amp board and the sound board itself, Plugged it in and nearly blew my eardrums, Volume was still un maximum,
Adjusted the volume and tweaked the small trimpots to adjust the explosion and jet sounds etc . What a huge difference all sounds can be heard now.. A few pics and one showing the sound board details for certain sound adjustments...
