Samick SM60RC guit amp schematic

[webber]

Would someone here know where I can find the schematics for the Samick SM60RC amp? Originally, it blew the fuse, after troubleshooting the bridge rectifier KBPC303, was blown. can't seem to find it anywhere can someone suggest an equivalent? thank you

[The Dude]

It's a 3A /300V rectifier. I would say anything rated the same or higher that is in the same case style would work. If you can upload a pic or verify case style, I could make a more specific recommendation. Datasheets I've been able to find have different case styles for the same part, so I'm not sure what you have. The ones I've found do all have the same or similar specs.

I took 2 pics but can't seem to get good lighting

[The Dude]

Pics are good enough, but no size reference. Please measure size/lead spacing and post dimensions. Also, are there markings for AC, +, & - on top of the device or the circuit board?

You could always look at specs for similar bridge rectifier and look at the size for a comparison.

Most anything will fit in there as it is wired off the board but very under rated!
I would fit one of these; https://uk.rs-online.com/web/p/bridg...ifiers/2278485
Mouser, Ellement 14 etc carry them in stock.

The size of the rectifier is 1.5cm X 1.5cm X 75mm aprox. Yes the +,- and ac markings are on the top. I simply don't know enough about these to select the proper one. btw, I appreciate the help.

KBPC-104 3A, 400V.. is this good or should I go 4A instead?

[Jon Snell]

The 4A version will be slightly more reliable and I would choose that.
If you lived in the UK, I could send you one for the cost of the postage.

Thanks Jon, thank you for the offer but, i think they're fairly cheap, I will try to find it locally, otherwise I'll order 1 or 2 online somewhere,
