LENOXX SOUND C-736G Boombox Overhaul and Bluetooth Mod

This is a really cute LENOXX SOUND model C-736G boombox. It comes with the original box. It was in good working condition except for cassette deck. Also, it had a very scratchy sound from the volume potentiometer. So I overhauled it then added the Bluetooth system.
During restoring the cassette deck, I encountered a heavy wow and flatter noise. So what I did was, 1) replacing the pinch roller, 2) replacing the drive belt, 3) replacing the motor. After 4 times of re-do, it finally started working properly. It still has a slight wow and flatter noise, but when playing the music, for me, it is OK. The successful combination was a new pinch roller + the original motor + the wider drive belt.
The Bluetooth mod, I brought the power for the Bluetooth from the motor, removed ground-loop noise by using DC/DC isolated power supply, and injected Bluetooth music signal to the volume potentiometer. I think I should add resistors between the Bluetooth signal and volume potentiometer, but maybe this boombox's amp will be able to handle it without resistors.
By the way, I just started posting pictures of what I am working with on Instagram.

Hello Mr. Teddy, how are you? I followed the whole video and saw how hard it was to hit the tape deck. I also have to go through this. It takes a lot of patience. I really liked the video. A big hug.

[@teddyhashee]

Hi, Manoel. Thank you for your compliment on my work. Restoring the cassette deck is sometimes troublesome, but most of them are repairable. Good luck on your work with cassette deck repair.

[@oldboombox]

Good job like always. :) respect

[@SharyffDaniels]

Hi teddy, love your videos they appeal to my inner nerd 👌🏿😂. I was wondering could you do a video on how to build the pcb board for the bluetooth assembly I'm kind of lost with that. Meaning how do you know where to solder in the resistor or capacitor on the board

[@teddyhashee]

Hi, Sharyft. You mean the board that will eliminate the ground-loop noise? The DC isolator along with capacitor and inductor?

[@badmanmelendez1]

@@teddyhashee yes, how do you do eliminate the ground loop noise?
