Selling as I was recently lucky enough to pick up a s/h RH750.
A great head- engineers have loved how clean sounding it is.
If you're looking at this though, you know all about these heads.
£370 delivered to most UK addresses.
Comes with mains lead and original manual all well packed in a TC box.
In very good condition with all controls and knobs intact.
