Delco car radio Peko vibrator converstion issues
#1

Hello Guys,
I am just finishing up restoring a Delco model 987087 car radio for a 1955 Belair .
Everything works and it sounds great but I decided to take a non-working vibrator not the one from this radio since it did work install this circuit board made by Peko Rf.

Anyway my issue that I am having is when the volume all the way down you hear high pitch  tone ? 
I was wondering if I need to change or add another capacitor has anyone worked with or dealt with this Peko board and had that issue ?

Here is a link to Peko RF https://www.pekorf.com/Radio.html

Here is a couple  photos of the complete amp/powersupply
