Dummy load for testing Pre 3 on 'scope.

[Riggers]

Hi all

After a long overdue chance to review my 8 year old WD PRE3 build and tidy up some lead dress and the like I wanted to test its performance on my oscilloscope. Being as it is a transformer output stage am I correct in saying it should run through a load before being attached to the input of the oscilloscope? And would we be talking in the order of 50K or 100K ohms? Would half watt resistors do?

Cheers in advance.

Phil.
