(yup = same way connected as yours)

Well, I hope to connect mine in a different configuration, within the next few days Magura

[Zen Mod]

will you insulate them of Danske Winter , with just sent styrofoam sheets ?

[Magura]

Something tells me, that they will keep warm on their own. The foam sheets are in need of visiting the oven, to get into shape Magura

I got the capacitors mounted yesterday. It may look simple, but making 2 holes and 3 radius line up with 2 angles....by hand Magura

Magura why do you want to cook RIFAs? They can take it - that's for sure, but they'll last longer if you give them a (thermal) break

[Magura]

Define "cook" ?Magura

Maybe it's just the picture that creates such an impression, but it looks like the RIFAs are attached directly to heatsink - and knowing you, that heatsink is going to be hot :character13:I'd put some thermal isolation between the RIFAs and the heatsink - that will prolong ELKO's life significantly.

that case will cook with 0,5KWit will be bored with wimpy 100W++ dissipation of Donut

Thanks for the hint. Usually you'd be right -but not in this case. Less than 10C above ambient according to my calcs. So the copper strips would actually be cooling the Rifa's.This is not my usual approach, as you have noticed, but in this case, it's an amp that's gonna stay in the living room, and the Mrs. should preferably stay as well Magura

I think you're not too far off. 0.5KW is about the limit for that case. That would be like 40C above ambient.Magura

not on top of giant blower:character13:

.... and the Mrs. should preferably stay as well

If that's the way the things are - you don't seem to have much choice :character13:But I wonder... women usually don't object the heat, it's the bulk that usually bothers them - big things use to scare them, and you got the opposite situation :rofl:BTW, I can't help admiring those crazy bolts you made, do you mind showing the screwdriver you use to handle them?

Oh, the Mrs. is actively participating in designing and so forth, so no problem there......but she has little (ok, none) tolerance towards open wires that are powered, or if she risks getting burned or shocked in general.

BTW, I can't help admiring those crazy bolts you made, do you mind showing the screwdriver you use to handle them?

Thanks There you go. It's not really a screwdriver, but a set of sockets for a socket wrench. The bolts serve their purpose well. They take up less space, than any other standard bolt type I know of, and can be tightened to their max anyway. The only drawback they have, is that they're fiddly to get the socket into, but not an issue for those few bolts. They wouldn't fly in an industrial situation, unless there were no other options.Magura

Ma jok, na brezonu je sigurnosna matica a Magura je ovo napravio kao sraf - ima glavu a brezon nema, njemu je jedan kraj sa narezanim navojem a drugi se sastaje sa tockom.
