For anyone interested, I've just fixed my RH450 and I have some leftover (brand new) rotary encoders and knobs for sale on the accessories board. For those wanting to do it, replacing the encoders was completely successful but does require desoldering and resoldering.
I've got:
5 x Alps Alpine EC12E2420803 rotary encoders (TC Electronic Part number 7E34002911)
6 x Davies Molding 1106WA knobs (interference fit)
These are all brand new. (I had to overbuy to fix my own RH450 hence the leftovers!)
£3 each for the encoders (plus postage)
£1.50 each for the knobs (plus postage)
Happy to do a deal for the whole lot.

Hi - I'm interested if this is still available. Largely dependent on where in London you are exactly (I'm in Reading), and the dimensions of the cab (I've got a small car!).
Thanks and best wishes,
Alex
