Hi Guys
Please DO NOT use inline images. Add them as an attachment that the reader clicks on to open. We cannot tell anything from the portion of the image available.
TUT3 shows thew correct way to ground an amp. Shared ground caps can be used as a single parallel cap for a single stage.You could "get away with it" as a SECOND Va cap + Vs cap, where a separate cap is used for the first-Va cap off the rectifier.
One detail that is important which can be gleaned from your drawing is that this amp is cathode-biased. There is no means added to huim-balance the output stage.
Apart from that, we cannot see how many tie points there are between the chassis and circuit ground - there should be only one. See TUT3.
