Request: Wiring Diagram or Service Manual for Intersound J-747S / Tecsonic / Promax Super Jumbo Boombox

[Sabum]

Hello everyone,


I'm currently working on restoring an Intersound J-747S Super Jumbo boombox and am looking for a wiring diagram or service manual for this model.


I know this unit was sold under various names, including:

• Tecsonic Super Jumbo J-1
• Promax J1 Super Jumbo
• Clairtone 7985
• Supertech J-747S

If anyone has access to a service manualor a schematic I would greatly appreciate your help.

Thanks in advance for any support or guidance!


Best regards, Michael

This is one of those non-big name boxes that typically never publishes a service manual, unfortunately.
