Is it looking the same like this ?:
Shin-ei Reverb-Mixer (RM-23)
Funny are the Shin-ei stamps on the schematic. As you can see on this poor picture:
Shin-ei Echo (RM-23) schematic
there is in the middle of the stamp "53 8." different to the "52 5." in your schematic.
I am wondering what that means and about the system of it.
On which DC-voltage the unit is running ?
I would spend it an 78xx voltage regulator.
If you can´t fix the problem I have a mod suggestion:
Remove R1, R30, C4, C8 and C16.
Place a jumper between the connection of C10/C11/R30 and the connection between C16 and the Volume pot and sell it as the "Super-Double-FuzzFace"....![]()
