I love your work. From memory, the 2nd and 4th pictures are your two Cracks, is that right? What are the first and third pictures of?

Also, based on my recent experience, I HIGHLY recommend that you consider replacing the two electrolytics you left in each of your Cracks...

Finally, can you remind me where you get that cap mounting hardware, or what you use for it?

Thanks!
Adam

Oh yeah, big caps!

Those big puppies look like the AmpOhm paper/oils... I go me some of them. I have to say though, they were just demoted to the subwoofer crossover duty. My new (small) 10uF Queen's are the Mudorf EVO alum/oil. Evo's are more "mature" IMO. In the spirit of disclosure, I do have them bypassed with a silver/oil. If I had the cash I would go with the silver/oil and be done.... Alas... We dream/pine.

I ordered up 2 Dayton 100 uF, 250 V caps as they were a quarter inch smaller diameter than the Solens.  Solens would not fit (or would be too close for my liking) and the Daytons fit nice in the stock base glued to the plate with silicone bathtub caulk.

Had to remove the 2 end terminals of the middle terminal strip, but that is no problem as they are just there for mounting the stock caps.

Far away from the bleeding edge

Well, that answers the question I asked in your post in the Gallery thread. Nice job!

I saw these Thomson-FSG86-9302-B-Film-Capacitor-100uF-400V on ebay while looking no good for me in the uk but thought that anyone US based might be interested.

I had considered picking up a pair of those, but wasn't so excited that the +/- terminals are on different sides, and you essentially need to use one of them to ground the thing and mount it.

Don't know if this was already mentioned but be careful, at 400V and the more Farad you have the more dangerous it gets. Energy of a cap: 1/2 * 0,0001F * 400^2V = 8 Joules. If you have like 5 to 10 times as much F this can be really dangerous if touched while fully charged. Caps are quite efficient to f**k someone up. (>20Joules can be enough).

Its always feels good when you arrive home from work to find the post man has left you a little brown parcel. A Russian Teflon capacitor For about the same price as a cup of coffee, it has just got to be given a try!

I'm a big fan of these.  They are the "Bang For The Buck" winners.  But I have to admit that the V-Cap Teflons are better at about 50 times the price.

Ahh yes the K72P, i have a few of them squirreled away. After i fitted FT3 teflons into my SEX amp (which made an amazing difference) i collected a lot of Russian caps to experiment with.  Never did get around to experimenting with power supply bypass caps as i cant figure out a way to measure/test the difference.

I have also used K75 PIO's in a CMOY build, caps are bigger than the amp ;D

I got a matched set of Russian PIO caps with my VTA ST120 kit.  I'm still building it so I don't know how they sound yet.

I use Russian otput caps also on my quickie with good results (k75 PIO bypassed with k72 teflon).
I found this pic on the net that shows how to connect russian caps, hope it helps.

Ciao!
