Tape section has been disabled as it was not being used. The record switch therefore does not have a function. That's why it was modified to make the VU meter work for the volume. Many thanks for your comments!

Interesting modification; so what you basically did was shifting the inputs of the IC from record to volume? So now recording and external signal can be monitored? A job well done. Thanks for sharing

Nothing special. The input to the TA7318 was shifted from the record switch to volume control; that's all! Many thanks for your keen observation and comments, dear Albert!

Technics are a good brand. You are the master of tape deck and CD repair. Well done Parasuraman.

After this badly tampered with Technics audio set already was successfully restored, it now even got a good db-meter upgrade to work with an external connected sub-woofer amplifier. Nice work on the TA7318P circuit modification although it was not entirely clear how the final circuit after modification exactly looked! Because only the original TA7318P circuits were shown.
