Greetings and salutations y'all,
I've found this forum after a lot of unsuccessful searching for schematics for the Baldwin Kustom 88 Electric Piano, soy guys are kind of my last hope Smile

That search included: emailing people selling a piano like this, people who uploaded youtube videos about it, contacting Kustom themselves, etc.
The problem is the following:
I got this piano a couple of weeks ago and a resistor on the Power SupplyPCB was blown
The resistor is unreadable (no color code left)
I know this resistor acts as a voltage divider for the -25VDC rail sending some of that voltage to ground before sending the remaining voltage to the MOTOROLA ICs 514-063227 (unfortunately I have not been able to find the specs of this ICs, they seem to have been custom made)
What i need to know is the value of this resistor (either a photo of a working unit's circuit or a schematic would help)
Thank you!

PS: unfortunately i cannot post a link until i reach 10 messages so here is the incomplete link to the circuit's photo, identifying the missing resistor (easy to spot with all that burnt material around)
