Once again - recap or not recap

So I guess I will ask again.

I have a receiver that now works on the bench after changing the electrolytics, only. I have run this set for hours without distortion, etc. Seems OK.

It is possible that even after this "burn in" that the wax caps could cause problems? Have you guys even experienced this, even after getting a set running well like this without recapping?

Sorry for bringing this up once again, but I have a great curiousity about it.

Seriously? I thought you had a blow up last time. For the low cost of the caps and enjoyment garnered from knowing you have brought something back that should be sound to use as a daily player, why wouldn't you?

Then again, there are some people who always seem to ask for advice, and never take it. I'm done.

Your radio will never be dependable if you do not replace all the old wax and paper capacitors. You could also cause damage to other parts, then you will be sorry you did not replace the old capacitors.

Thanks John and Warren ...

Please be patient with me. I am an engineer of many years and I am used to questioning things a lot so please don't be frustrated!!

I will indeed follow your advice. Seems like even when these caps ARE working well they are still a liability. It just seemed to me in the latest instance that I was replacing good goods but you are indicating that is not the case - OK.

Once again - I appreciate your infinite patience with me!

Hi Lou,
I've had a couple radios that worked just fine without changing the electrolytics or wax/paper caps but it is rare indeed to get any like that. I've long since sold them and the customers wanted them as is. Personally I always like to change all of the caps, and check the resistores. Then I know I have a set that is reasonably safe for daily use. Problem is you can't see under the chassis when the set is playing and any of the caps could have a melt down and do damage or worse catch fire. By that time it is to late, and then you will probably have much more to fix like coils and transformers. Always best to change them and then you can listen to it without the worry. Good Luck, George T

Thanks Again George:

PS I got your DVD set in the mail today. Thanks much for the hospitality.

My original career appears to be on hold, so from now on ( at least for now ) I am going to have to become the greatest antique radio officionado known.
