Emboldened by your findings and subsequent modification, I went straight for TR5 and swapped it for an MPS6516 - simply because it has EBC moulded into the casing. Unfortunately there was no improvement in the hiss level so I'm going to have to be more scientific about it.

I freed up the wavechange switch by dripping some light oil down the shaft from the top. Working the switch a few times and the back of the knob broke. My bad. It should super-glue together.
