re: SX-434

Blessed be the soul of TibouTip, thank you very much for the owner's manual for this receiver. I bought mine dead, but I got it fixed and now it's all pretty and sweet and nice sounding and I love it very much and I use it every day. Thanks again.

What was wrong with your receiver?

re: SX-434

I would like to plug in headphones to my sx-434 but the plug size is much larger. Is there an adapter I could use to make a connection to the 3.5 mm plug?

You need a 3.5mm to 6.35mm jack adaptor, they have these everywhere. Find a local audio store or get one on the bay.
