caps and diodes for the lm3886

[impsick]

i was wondering if its possible to use 50v 4700uf caps on the psu board (chipamps board) with motorola MR751 diodes instead of the recomended?

all i need to know is yes or no, explanation would be great but i dont want to waist all your guys time. thanks.

Probably. What voltage is your transformer?

I used NTE fast switching diodes for my prototypes....same basic specs/tolerances. You should be fine, but just to make sure I would see if I could cross-ref the diodes and see how close they are.

On the capacitors, you should be fine...just stay within the voltage tolerances....

I have used some "Crazy High" capacitance....with great results. I salvage alot of old capacitors, well parts in general for my projects, and try to use what I have lying around before build the final product....

Have fun!!

thanks guys for input.

paulb- i havent picked out a transformer yet. i have a few i pulled from older gear im just trying to figure out there ratings.

yes

I have also found that if the transformers are marked in some way, you can usually look them up on the internet. Many will have part/serial numbers printed on them.

I have several that I have salvaged from UPS units and older HiFi equipment.
