Fender Roc Pro 1000 Reverb Not Working

[mercom]

Hi Guys,

I have a Fender Roc Pro with no reverb. I tested and replaced the tank. I now have a springy sound through the amp when I tap it but no but no change to the sound when you play through it. I connected a headphone speaker to the tank input cable and found that there is only a very quite sound emitting. The only other thing that I can add is that the amp hums louder when the reverb is selected via the foot switch. Is there a transducer or something that I can test? You can see the scematic here and if you can point me in the right direction would be much aprieciated.

On the schematic, did you check U10A ic?
There are some voltages labeled for Reverb On & Rvb Off.

Thanks for the reply,

I cant find it, would you be kind enough to give me the grid coordinates so that I could find it on both the scematic pages and I will test it and return to you.

Kind regards.

U10 A coordinates

The U10 A ic is located between B & C / 8.
There is an arrow pointing right to it.
How about that?
