Very detailed product, also it is a scanning from original, very useful if you have to service this type of amplifier ! Very good product, very hard to find!
;
the Manual was made available as promised, the scans were excellent..Good Work !!!
;
It's complete and helpful manual with good quality of scan. Thanks very much.
;
The service was quick and simple, finding the service manual easy and it appears to be the original with colour schematics. It contained the info I was after and so sorted the problem.
I have copied it to CD and attached the envelope to the inside back cover of the owners manual. Good manual and excelent service. Robin Wood, Wood Electronics, New Zealand.
