Blockbuster low volume out put on tape only

[FRizzo17]

I have a Blockbuster GE boombox. Im having problems with the volume in the tape mode. Sounds fine on radio but when listening to tapes, ill have the volume half way up on 5 or 6 and it sounds like its on 1. Any thoughts appreciated.

if you have a blank tape put it in the tape deck and press play record at the same time and then stop and then repeat this several times what this does is it works the record bar which allows the signals to pass through the tape deck.
