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.

Exactly what was needed to assess the product - excellent value and great service
