Good Witch or Dead Witch?

Recommended Posts

Those who know me know that tech isn't my strong point. OTOH, I've been around long enough to at least look before giving something the toss. I have a Panasonic SA-XR 70 I really like. Thing went silent. That was quite a while back, but as I had other options I just stuck it back until I had a need to open and take a look. Here's what I found and want to know, if in the opinion of those who actually know a few things, if it's worth my while to replace the referenced capacitor. I realize that even if this is fried, it may have acted as a fuse from deeper issues beyond my abilities. OTOH, perhaps this is it. Fuse is fine, and power light shows red when powered, but nothing at all happens when you hit the power switch. This cap is very likely part of the power chain due to it's position. What do you think? Front and back of suspect cap, and shot of where I clipped it from, marked Z70. JK701 is mains power in.

Thats not a cap... looks like an mov, like what you ha e as protection in outlet strips. Did you have a power surge in the house when this went dead?

I was right, I just googled the part number. It probably gave its life to protect the amp. I would try replacing it. It is a current/voltage absorber/suppressor.

No idea when it went south really or whether it was on a surge protector or not.  Appreciate the info, Bruce, and will see if I can locate the replacement and put it in. Not sure what part number is as there are three line, but can figure it out.

V10511u is the part number. Just google it... it's a panasonic part or equivalent.

While replacement of that part is pretty much a forgone conclusion at this point, I'm curious if it's even bad.  Does it exhibit continuity?

Well, I assumed it was a cap. In my day, one needed a VTVM to check a cap. Don't have one now, and assume there are modern ways. But I think between Bruce's opinion and my own close up view of it as well fried and magic smoke gone it's worth 6 bucks delivered to replace. Beyond that, the thing goes to the street. Sad, but with techs now a thing of the past it's the way things are.

There's an entire industry of people that service stereo equipment.

 

If you can't fix it yourself but love your Panasonic, search the internet and find someone who can.

 

I've kept my 20+ year old Yamaha amp alive this way.
