And here I thought you might be leaving the Aegis club, but you're actually going to build a second lol.

I think we’re both addicted to DIY. Even the idea of picking out new colours for the chassis, different caps, etc, make me giddy with happiness!

Remember when DCA released the alpha dog as a diy? I made three over the years. I kept trying to make them better and better.

I thought I would mention a new tube roll that I've really been enjoying. Bendix 6106 (military grade 5Y3), 5691 red base, and Fivre 6V6 power tubes. Very musical and open.

So 600v 10uF rather than the 22uF.

Will this impact on other rectifiers at all? So far (touch wood) the Elroy has been spot on with 650hrs of use.

10uF 450VDC should be fine, if you want to derate higher than 450VDC you can. Here is a 10uF 500VDC 12,000hr option:

https://www.mouser.com/ProductDetail/Rubycon/500BXC10MEFC12.5X20?qs=T3oQrply3y%2BuesHti96zMw==

It will just mean a lower inrush current for other rectifiers as well. There is slightly less filtering in the power supply going from 22uF to 10uF, but there is an excess in Aegis anyway, I don't expect it will change the noise floor in any appreciable way.

This is one of those things where I can't say with 100% certainty every 274B will be fine. High quality ones will be okay with 22uF input cap in Aegis, but I'm less certain for lower quality 274B, in which case the precautious thing to do is use a 10uF cap. And using a 10uF cap with any 274B will be more kind to it over time. Given @miter53 brought it up, I may steer people with ZMF Aegis away from 274B as they do not have the option of reducing the input capacitor. Sophia could be fine, but I would hate for it to arc on someone.

I love Jupiter caps, and have also had great experiences with duelund. Ive read great things about vcap but haven’t heard them.

When building my next aegis I’ll probably go Duelund for variety. Can’t really go wrong with any of those three as long as you’re matching or beating the specs.

I can highly recommend the V-Cap ODAMs. More clarity and openness than the Jupiters, much smaller also.

Well, it’s an easy an cheap tweak. I may even drop an email to Takatsuki when I’m at that point of buying one. May just pick up the Cap anyway. Thanks

I feel like if anyone is gonna end up with a modded Super Aegis its gonna be you . You're halfway there already!

Well… I try my best

Those 11mm RCA cables with triple shielding were a bit of a push I do admit I was down to 2mm spare and that was after using a 2mm steel rod to allow the impedance dial to be mounted on the front. I was trying to avoid the volume pot being too close to the power supply and the 2 dials being too close together. In the End, the vol dial had the same space from the power even with it being centred. Threading the solid core wire from the PCB to the sockets was interesting as well

@L0rdGwyn Thomas from Elrog has said the it should be 4uF as well. So, obviously this will impact on tube life but, what options would be best if you wanted to continue using the Elrog 274b and what impact would it have on the amp? Cheers

I think that's overly conservative but if he insists lowering the cap value to 4uF will slightly lower the B+ voltage and increase the amount of ripple. I would still expect the ripple to be inaudible, so should not adversely affect the noise floor. I would just use 4.7uF which is a more standard value.

So, something like this one then

The ripple current ratings of these low capacitance electrolytics aren't going to cut it unfortunately, you're going to have to use a film cap, in which case 4uF may be a value that can be found. Something like this:

https://www.mouser.com/ProductDetail/KEMET/C4GAJUD4400AA1J?qs=pqRVuuzkf6YJ1n%2BaWfq2tQ==

The downside is it is large, 44mm L x 33mm D. Should be plenty of space if you need to use a longer terminal strip for it. Maybe use one of these:

https://www.mouser.com/ProductDetail/Keystone-Electronics/818?qs=1rIBfDHV7icx5KT4oK8G2g==

You can clip off the two interior tags if they aren't needed to get them out of the way, or fold them down.

Another option to secure the cap is to use adhesive zip tie mounts.

Excellent, thanks. I’ve ordered one of those and a couple of the 10uF rubicons you linked to as well…. Plus a spare original 22uF. They’re cheap enough and given the delivery charge is way more than the items, I may as well order them in case.

That’s one area of the chassis I have plenty of space. I’d like to maintain the the possibility of using the 10uF and the 22uF so may come up with a custom bracket to the right of the current one so I can connect to it without disturbing the existing wiring. Will proximity to the choke be an issue… or the length of wire from the capacitor to the terminal block?

Can I use this for Aegis ?

Guess it will be harder to secure.

That should be fine, but I always defer to LG.

It's a bit more, but I'd also look at: https://partsconnexion.com/collecti...er-foil-capacitor?_pos=4&_fid=2278feb94&_ss=c

Also what are the thoughts on the nextgen rca connectors being worth it? They are pretty pricey. Any good sounding cheaper alternative?
