Sansui 1000a rectifier value

[James Cox]

Hi, im working on restoring a Sansui 1000a. Ive got the parts list together except i cant figure out what value i need to getnfor the rectifier diodes. Tried searching but came up empty. Any suggestions?

What is the type number of the original rectifier you are trying to replace?

 

[James Cox]

They say SW-05, there are 3 of them in the sansui i believe

The SW-5 are a replacement for the SD-1B which was rated for 180VAC @ 500ma. A 1n4004 is plenty enough for these 3 rectifier diodes. The UF series is a waste in these units. https://www.mouser.com/ProductDetail/ON-Semiconductor/1N4004G?qs=y2kkmE52mdNg%2Biqv0rMpBA==

Cool thanks ill grab 3 of the 1n4004s then. The unit currently works but is mostly original aside from power tubes and coupling caps so i want to get the rest of the problamatic parts changed before I put the unit in heavy rotation. Thanks for your help!
