I think this may have helped me solve a problem I've been having.
For me, the 6V feed is only measuring 3.68V. I have followed it back to the PSU supply pin no.3 and am only getting 3.77V instead or the required 7V.

Can you recommend a solution to fix this. I assume a component in the PSU is defective, but I am not skilled enough to follow the circuit back to the defective component.

I have replaced the 4 x 35V caps as I thought that may have been an issue.

Any help you can provide would be greatly appreciated.

Regards,
Hoffy.
