The Capstan Servo Card is the 'pacemaker' of your M79 recorder!

This board keeps your M79 'on speed' and so it's important to service these little boards after their 30 to 40 plus years in operation!

We completely go through the board and replave the caps and test the board for speed accuracy. Any marginal or defective components are replaced and the board is trimmed to factory specs.

We then thoroughly clean the servo board in an industrial ultrasonic cleaner and then we apply contact preservative to all edge connector contacts.

The entire Logic Board is placed in our 100 degree F Hot-Room for 24 hours in a special test jig. Then after the 24 hour burn-in, we re-test the Board again to make sure that all finctions are operating correctly to spec before shipping it back to you.

We warranty your rebuilt board for 1 year, parts & labor (excluding misuse, user modifications, water, flood, liquid damage, powerline & lightning voltage surges, abusive environmental temperatures extreemes). Shipping charges, not included.

Once you have placed an order for this service, please send in your M79 Capstan Servo Board to us via insured UPS or Fed-Ex.

Be sure to DOUBLE BOX your shipment using plenty of packaging peanuts. And be sure to INSURE your shipment! GRS Systems is NOT responsible for damaged shipments and UPS and FED-EX will not pay damage claims on poorly packaged shipments!

We will let you know when we receive your Capstan Servo Board and we will give you an initial performance report by email.
