Hi,
I have a Beta lead that has seen better days. I aquired it as a debt repayment and it has stood in a garage for a number of years. I have to get an electronic repair man in town to fix it as I don't have the test gear. I downloaded the service manual but it doesn't print out too well as a .jpg (no offence to whomever took the trouble to scan and post it). I'm in the process of re-creating it and wondered if you would like it as a .pdf which should print a little clearer. It might take a while but you can have it if you want it.
Cheers
Bigyin
