http://theartofsound.net/forum/attachment.php?attachmentid=12124&d=1398004851Up for grabs is the highly rated Sony F670-ES which has just been checked and tested and had parts replaced by James: (istari_knight) who is rather an expert on these amplifiers.
This is what he done to it and then said this about it:
"I replaced the volume potentiometer [which is a sealed dual logarithmic audio taper model - Alps Blue Beauty variant.]
Completely stripped it down & cleaned/dusted everything.
Cleaned & lubed all switches & controls.
Cleaned protection relay switching contacts.
Gave it a general health check [no overheated components or dead/dying capacitors.]
Checked DC-Offset [Its fine.]
Reset the quiescent current [bias] to factory level
Its the finest example of a 670ES I've seen & would rate it 9/10... Its quite literally spotless inside."
Im looking for £199+UK posting and payment by paypal gift...collection also possible in London.
