Service manual of INT-30A

[jardalukas]

Hello.
I purchased an INT-30A and unfortunately I need to fix a fault in the volume control. Unfortunately, the service center is not nearby and it is very difficult for me to move around.
I can't find a service manual anywhere, so please if someone can help me and provide me with a service manual.
Thank you for your help.

Good evening.
Thanks for the advice, but unfortunately it doesn't solve my problem.
I worked for 10 years as a service technician in SONY, so I can repair the equipment myself.
Good evening.

If you have the serial number or board revision numbers we should be able to supply whatever you need.
There isn’t really a service manual but schematics and board diagrams exist.

On the INT-30a the usual Rx is to re-flow the pads on the volume chip. The early lead free solder could leave a pin on the chip, high. A few minutes under a stereoscope at about 20X normally tells the tale

Thank you. I'll look into it this weekend. I would also like to check and adjust the voltage and current. Is there a setting procedure and parameter control?
Thank you.

No adjustable voltage regulators in the INT-30a.

A product serial number would be helpful.

I will take a picture tomorrow and send it.
