What are y'all doing to stick the filter caps together?

Hot melt glue for me.

Are folks gluing them to the chassis as well?

I hot-glued them together, then cable-tied them to the chassis.

It's not a TWreck, but in another amp I used a silicon based adhesive. It's solid and more resistant to heat than hot melt. I'm not saying this is better, just that it was successful.

That's what I use.

I've used RTV in similar instances. Works great. Never tried it in a 'Wreck though.

I used ProSeal Instant Gasket...it's blue like the stuff in Dumbles.

Main reason I posted is that many of these silicon adhesives/sealants release acetic acid vapor while curing (that's the vinegar smell) and it could possibly corrode something if 'sealed up' while still curing. Probably a non-issue but I always let it fully cure before buttoning it back up.

I used Shoe Goo [img:200:443]http://www.eclecticproducts.com/_images ... g_main.jpg[/img]

Its been almost a year now and the caps are as solid on the chassis as they were the day the glue dried. I use this stuff for lots of applications.

I have some of this stuff:

I simply put the caps in place, and painted some of the conformal coating onto the caps, avoiding the electric leads, and it basically wraps them all in a nice coating of silicone like material...it's pretty strong and keeps them on the chassis very solidly.

I have concerns about adding too much of any kind of goo, that it might create a hot spot on the cap. IMO, these should not be gooped or coated. Use the minimum amount of anything that is rated for adequate temperature and use something that isn't impossible to remove. I for one, have never gooped a cap to anything. I have tie wrapped on occasion to keep them in place.

Stay tuned. I'm nearly done with my Franken-wreck express. I strayed from the fold here, using off brand caps that are physically smaller and tied them in a single plane to either a board or terminal strips. No goo for me. I'm hoping to finish this weekend and will post pictures.

Hopefully my layout will work. If not, I can always try again.

At the risk of further heresy (see IEC power inlet thread), I really dislike the idea of gluing 5 capacitors together and then gluing them to the chassis. I much prefer a small power supply board and/or LCR-style capacitors. Or turret strips with the caps strung between them, perhaps secured to the chassis with some hot-melt to keep them from wiggling, but certainly not glued to each other. JUST my opinion/preference here.

household goop. same thing as shoe goop. need a pair of pliers to remove anything.

do not use silicone. it outgasses acetic acid. bad for aluminum and rubber gaskets.

I'm with you, electrolytic capacitors are not meant to be installed packed onto a big pile to my knowledge. The main enemies of capacitor life are temperature and excess voltage and time, I believe. Certainly keeping them cooler can only be better for them. I use cap boards for almost all my amp builds.
