I dunno.... the guitar guys like these things even when they're darn near shorted; Don't ask me why. They want them and they have their reasons, I guess. Here's an interesting thing: I toasted another handful at 160 degrees for an hour. With one exception, the cases did not split and they did not leak wax. I didn't expect much improvement, but was quite surprised. These caps were way beyond what I'd try anywhere, all over 1 mA. One even leaked at 5 mA+. With the one exception of the case splitter, they are now 100 microAmps or less. Two are less than 10 microAmps. I wonder.... Since the cases did not split, and it's possible that the core temp of the caps didn't get to the full 160 degs in only an hour, is it possible that the problem is not with the paper at all, but something to do with the Bakelite? I've already proven that Bakelite will absorb water and it can be driven out with heat; I free-up those large PL-** connectors that way all the time, and it's the Bakelite shrinking, not the metal expanding, because they stay freed-up after cooling. Afterall- Dr. Barry isn't going to be wrong. If acidified, rotted paper isn't recoverable, than my treatment should not have improved them so markedly. Yet it did. And if it the paper can't be recovered, yet these caps *are* recovered, than it isn't the paper. Getting more interesting all the time ;-). I'm going to leave a few of them at 250 volts for a couple of days and see what happens. 73 Dave S. ******* I don't know if others feel the way I do but if you have read Scott's posting :- "Well, that's about 40 megohms DC resistance after baking. 10 uA in a 1 Meg grid leak makes 10V bias, enough to toast your 6V,F,K,or L6s nicely. Even 5V in a 500K grid leak is enough to upset an audio PA's operating point, and it will almost certainly cut off any earlier voltage amp stage. The little yellow caps we have all been using for some time measure about 50,000 megohms; Sprague orange drops measure over 500,000 megohms, the upper limit of my GR megger. These measurements are at 400V, as are yours. Interesting result, but, I fear, still not good enough for general service.

Dave, I suggest you dry them in a "warm" oven, less than boiling temperature for sure.. then they might not split. THEN, dip them in some marine varnish thinned maybe half and half with VMP Naptha so the coating is not as thick as it would full strength. MAYBE that would prevent future water absorption and hasten what might be a long drying time.

But what it is, your logic for the amount of information you accept is flawless. As I said a paper cap is considered good if 5000 megohms or so. Sprague knows (knew?) what they are talking about? Now you can un-rot paper? Driving out the moisture of course will increase resistance. But you are a long way from 5000 megohms. Does that tell you something? Giving credance to any of the audiophoole quacks is behaving like kids who stomp mud puddles after being cleaned up and sent out to play again.

The leakage is caused by aluminum migration through the sulphite pulp based kraft paper dielectric. Any moisture only serves to facilitate the degradation and is not its root cause. A leakage current of 10 microamperes at 400 volts is NOT a low value of leakage and is totally unacceptable. This represents a leakage resistance of only 40 megohms, and if used as a coupling cap will almost certainly upset the grid bias on the next stage. If they were to show leakage currents with 400 volts of applied DC of 0.1 microamps this would represent a leakage resistance of 4000 megohms and would be MARGINALLY acceptable. Not to put too fine a point on it, bumblebee caps are real crap and the only place for them is either in a (non-functional) display item or in the garbage wagon. 73...Doug Bannard ------------------------------ Message-ID: <001e01cac673$d8bfaf20$ad9d480c@KB6NAX> From: "Arden Allen" To: Old Tube Radios Subject: Re: Recovering "Bumble Bee" Capacitors Date: Thu, 18 Mar 2010 01:20:13 -0700 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit > ......I think I'll play with them a little more. Following what Scott said you are wasting your time. Radios get hot, the leakage at temp is what you will have to deal with. The Sprague Tel-Ohmike manual recommends 5000 megohms or more for a good capacitor. You may remember from quite a while ago Dr. Barry Ornitz explained the chemistry of deterioation of paper capacitors. Moisture invading paper causes an acid solution to develop that rots the paper. Its insulation properties go south and are not recoverable. About the only materials that will hold off moisture for many years are metal and glass of high quality. Barry also explained why metalized plastic film capacitors last a long time. The metal fused onto the plastic is what acts as a moisture barrier. You may have noticed some food products are packed in metalized plastic bags - like a lot of militarized electronics parts are also.

He has extensive experience with > "Bumble-Bees" and "Black Beauties.... Thank you for showing this to your friend, Ed. The key folks seem to keep missing about the possible recovery of these caps is the leakage measurements *at 400 Volts.* Please get "un-stuck" from that data point. The leakage current is directly proportional to the voltage applied. No, they will not be acceptable at high voltage. But most of them would work just fine in low-voltage applications. The caps in some of my "ARC-5" receivers are worse than these at full B+, but I've run some of them at very reduced B+ for years and years. They work great and no damage. A few "experts" told me that wouldn't work, too. They were wrong. If I were to tell you: "I tested a .1 uFd cap at 50 Volts on my tester and it showed excellent spec and ESR with immeasurable leakage," you'd yawn and say "of course."

OK. I respect the man's point. But my long experience with engineers has taught me they sometimes get focused on one thing and "miss the forest for the trees." Heating the caps will not "un-migrate" the aluminum, but it does drive out the water. Driving out the water drastically reduced the leakage current. Therefore, the water is a factor in the leakage, and it is likely the combination of water and dielectric contamination we're dealing with, not just the aluminum migration alone. If we remove the water, we're left with the aluminum contamination. Some will have migrated worse than others. Therefore, some should be useable at reduced voltage spec and, indeed, testing proves this to be the case. The question of something electrical going-on with the water absorbed into the Bakelite is still open, too.
