These upgrades help to eliminate noisy audio channels, restore EQ switching performance and help to restore lost low frequency response attributed to aged electrolytic capacitors.
The NEW high performance record and playback amplifiers lower distortion, lower the noise floor and greatly improve the frequency response of the audio channel.
Every board is burned in for 24 hours and then the audio perfomance & noise performance levels are re-tested again.
Once you have placed an order for this service, please send in your audio boards to us via insured Priority Mail, UPS or Fed-Ex. We will let you know when we receive your boards and give you an initial performance report on your boards by email.
When your boards are ready to ship back to you, we will notify you by email and provide you with a shipment tracking number.
