Intermittent DC voltage on right channel of Pioneer SA-606

If the amp uses 2SA798, replace them with a matched pair of KSA992 . They are going bad by this time. Probably the heat of the soldering iron fixed it by now, but I bet the crackling noises will be back.

Thank you so much for the warning, will do it.
 
I actually have found the 2sa798 transistors online but when the problem solved i gave up on buying them but i will buy them now.
 
I'd get pairs of ksa992, and not from ebay.

There is a whole thread here at AK called "double transistor 2SA798 is there a replacement? " with the replacement options.

How about these? They say these transistors are new and original. Read their description please, they say "
- Parts labeled as "original new" are brand new and made by the original manufacturer.
- Parts labeled as "pulls" or "pulled" have been previously installed and are made by the original manufacturer. (these parts are checked for functionality before we purchase them)
- Parts labeled as "generic" are brand new and are made by third party manufacturers. (generally, the original parts offer superior quality over the generic)"

So according to what they said, the parts must be NOS.
