Just had another bit of luck Technics-wise, this SU 7300 was on a back shelf of a charity shop I happened to take a chance stroll into - its nearly mint, only faults are the missing power switch toggle cover and one very small mark to the aluminum face - the wooden cover is totally unmarked and inside there is not a speck of dust, looks hardly used. Got her home, cleaned her up outside a bit (not much needed) and fired her up. Has almost exactly the same sound as my daily listener, the SU 7700 you can see in a few of the pics. DC offset is at 6mv left and right and there is no static in any of the controls, shes a beauty! Not sure if shes a keeper yet as I dont have the need for another amp and I do have the need for cash

And the cost? £25
These seem to sell particularly well on ebay UK, usually topping £100, so I shouldn't loose out.
