Hi Sparky.

I own a Setton RS-660 and in my holly quest (!) for a high def service manual, I've seen your post on hifiengine concerning your "Scanned 300DPI from an original paper copy... with
schematics and board layouts clear and complete" Unfortunately the link is not working and I cannot download it.

I would appreciate very much to get to scanned copy if possible. Thank you so much in advance.

Hi Sparky. I’ve been instructed to reach out to you. Here’s a copy of my thread without the pictures. I’ve read your posts and looked over your photos with no success. I believe your the go to for my mystery. If you have a chance could you please go to my Thread ( Lafayette LR-9090 Mystery ) Thank you

Sparky, read your thread on using the Altenistor on the Alps switch in the Lafayette LR-9090. About to do the mod to mine. Want to catch it before if fries. Is the mod still working for you? My alternative is to of course wire in a relay, but I like your mod better as you have stated.

Thanks,
Perry

Hi, Gary the New Guy here again.
I checked the DC bias on my Setton RS660.
Left CH is around 8mV, Right CH is around 30mV.
Should I be concerned? If yes, what is the recommended fix?

I have looked for a fix and was not able to find one (possibly a because if am New to this site)

Hi,
Another member suggested I chat with you.
I am currently fixing a Setton RS660. Your repair notes suggest to change C18 on the Left PA from 47 to 220 uf. My Setton does not have C18 installed on either PA board.!
Is this normal? Were there production changes? Or should I install the cap?
