Hi to all,
sorry for my english but I am an Italian User,

Does someone knows where to find spare parts for this amp?
I need the Stereo/Mono switch (the same in many models) because sometimes it doesn't work and i can't hear sound...Or how i can repair it if is it possible,

Thanks!
 
Clean the switch with a product called " CRAIG DEOXIT " . It could be dirty. If you do a search here, you will find lots of information.

HI! FINISHED NOW!
spray purchased and used, all now is working fine :)
Good sound!
I also used an electronic cleaner to remove dust and oil from the PCB :)
and put 3 dissipators on 3 transistor to prevent damage...
Tomorrow i'll post some photos.

I'm thinking to recap some capacitors, specially the 2 big power capacitor of
12000uF that i think they could be dry.
Some info about which cap should I buy? I can only find it on ebay i think...

Thanks, goodnight!
 
Try here. I believe they ship overseas. If not at least you can find what to look for over there.

The Panasonic series of big caps are well thought of. You need to find out if they are screw in or snap in type capacitors before you search. Snap in caps have little pins on the bottom. Screw in is obvious, the contacts have screw in posts on the bottom. Good luck to you! Ciao.
 
First we must know the diameter and height of the original capacitors, the values (xx,xxx uF and xx volts) of the original and the appearance of the terminals of the capacitor and how they are connected.

Perhaps a picture.


Select the voltage first, then the available capacitance (uf) will be displayed.
Then the diameter and height are selected if there is a choice available with that value.
 
Well I was just about to open my big mouth, and realized that the cap list I put up was for a SA-706, not the SA-708. Ill stay quiet now.
 
Hi, I'm back...

Thanks for your info, now was time for one more cleaning after 8 years...

Do you think that I have to recap all little caps?

I don't know if some were changed by previous owner...

I will upload some photos...
