Service Manual for Sansui RA-500 Reverb Amplifier

caxambu's picture

I have tried everything that I can think of to be able to download the service manual. What I am looking for is the proper fuse to use. The unit that I have is missing this. On the back it states 100/117V - 0.5A; would this be the correct fuse to be used?
Thank you for your help.

Fuse rating

Yes, the fuse is rated @ 0.5 amp @ 100-117 vac.

HI FI IS AWESOME

Sansui RA 500 Reverb:

I spent some time in SouthEast Asia in the US Marine Corps and I had a pick of spending time away from war in a nearby country of Sasebo & Yokusko,Japan. Had a bunch of US dollars to spend tax free on whatever my heart desired and I chose to make some of my purchases in Hi-Fi equipment. At the time in 1960's thru 70's Sansui sold very well made Audio products. I bought a whole system -Amp/Rec;Tape decks,Reverbs,Speakers & Belt Drive Turntables just as 10's of 1000's soldiers & sailors did TAX FREE.I still have these old vintage audio components and lost some of the manuals through the years.It's been 40 yrs since and I just about gave up finding mauals that date back this far.I want to thank you for this it made my day! I will always keep your site handy because I now have other older manuals that are in bad shape. Most of my war buddies still have their very 1st stereo systems,it's like a war chest,you keep, store it because of memories.
