The transformer might be under-sized... so it can't provide enough current, so the voltage is dropping. Does the transformer get hot?

In my ongoing P6 power supply saga, have got UK transformer hooked up ok but test points are reading
+5 = 3.6
+15 = 10.8
-15 = -10.7
Is this likely a problem with the transformer or more likely the voltage regulating components on the 376 board? Rectifiers shot?
Have tried adjusting trimpots but that does not make result in a noticeable voltage difference on the test points.
Have tested the two main Caps and they are within tolerance.
Any help or ideas appreciated.
Cheers
