Proline 3000 Input Board

[shehantha]

If any one have proline 3000 amp please try to give me below mention components values if possible.

input board ,

R207 , R208 , R209 (Schematic R909) , R210, R212 ,

please try to give me above 5 resistor values correctly

schematic mention values are not the correct values. pls kindly check the input board physically and update.

thanks for kind help.

None of the values are critical so it will make little difference what values are fitted, unless completely off the scale of course. Eg R209 at 82k instead of around 8k2 etc.

thanks for the reply JonSell, but if anyone own the amp and physically check and reply me if possible. That will be highly appreciated.

thanks

I've attatched a picture. Have fun decoding the rings 😛
Use metal films as replacements.

While you have the board in front of you, you could change all the 4.7µF bi-polar capacitors for MKT/MKS ones of equal or higher capacity and voltage. And C217/C218 (as well as C215/C216/C218/C219 on the power supply board) for bigger capacity, low-esr ones like Panasonic FR or even solid polymer capacitors. At least I'd do that, if that amp were mine...In any case good luck with your project.

Dear 1210, Many Thanks for the reply and attached picture. Your picture is really quality than my picture. I downloaded the same picture but the quality is not that good.

Audio Verstärker an Bauerndrehstrom - Mikrocontroller.net

but in your picture I can reads the resistor colour codes easily.

Anyhow Thanks for the kind and Quick help and reply .
