It's really not that expensive to just replace all the electrolytics at once.


Just my opinion...

What Casey means is that the power supply caps must be certainly dry by now, replace them with fresh ones, and since sizes have shrunk along the time, you probably can easily fit at least 2 X as much capacitance in the same board, which is good.
The hum is a symptom , and the sputtering low frequency sound is motorboating, both caused by dying filter caps.

Thanks Mr Fahey  :tu:

I guess I didn't say enough for a change...

Does it have all the original power supply caps?

This is just my second post here, but I couldn't help notice this thread.   I have used a ligt bulb limiter several times, it's a quick easy way to safely control startups and testing.

Here's my take on the limiter...

I just joined a few minutes ago so this is my introduction post.  I found this site link at the GKB site BTW.

I am not much on SS electronics so this will be an interesting site to learn a few new things.
