Bush TR 82C repair advice wanted

[ducatiguzzi]

I've measured the voltages from the volume control onwards and they all seem about right give or take a bit, I'll post them if its of benefit, comparing it to the MKI service sheet. I have spotted at least one difference between the MKI & 2, I have an extra capacitor between TR4 and TR5. The only one that stuck out was 9.5v out TR6 and 7 push pull, a bit high?

The AGT (C21) measured 13 uF on a digital multimeter for the stated 8uF with one leg lifted but I didn't measure any DC voltage out of it.

I'll see if I can source the red black and yellow caps and the AGT cap, is there any particular characteristics I should know about?
