Re: re-cap kits
Ok...I'm not understanding this recommendation to stay away from Sprague ATOMs. I've used them for 18+ years in repairing amps and have had zero failures. I realize that the larger bodied capacitors actually contain a physically smaller capacitor inside now but I really don't see it as a reason to blacklist them; the value (and voltage rating @ temperature) is the important part. Of those that go under the hood, I still have customers that don't want to see a replacement capacitor that's smaller than the one it replaced. I stock some of the other brands for those that want to see a full size replacement can have that if they are willing to pay the extra cost. Sprague values are nearly dead on to the stated value and the lower derating temperatures make them behave more like the originals they replace in older amps (when the amp heats up).
In your Marshall, you would only be using the smaller body capacitors that aren't a cap in a cap; the large cans will have to come from somewhere else. Sprague offers values that you can't get anywhere else (in the smaller caps) which can be important in certain situations. All of the odd values in my inventory are Spragues...and I use them quite a bit since I repair mostly vintage amps.
If we're gonna blacklist a product, let's do it for quality/reliability reasons.
