Double-checked the gerber file of the Megatron XL today. It shows 47uf caps to gnd nearby the 12AX7. Don`t know if it should be .47uf instead of the 47. The rerber file name is megatron12vxl3fp ver .27

I don't know that there is much difference between them, and since I've never been successful mounting the QFN packages, I don't know about any heat difference, but I would think the regulator contribution to this is swamped by the 32 PZTAs. If I could have mounted these successfully, that is the way I would have gone. After building 4 of these, wishlist for changes/additions to the board would be: Addition of Kevin's balanced protector circuit, with a manual mute switch. Implementation of a delay circuit (5 seconds) for power application to the board to allow for the Meanwell bricks to come up at the same time. I determined that this was the source of the large DC offset I was seeing on the SE output when the amp is fired up. #1 above could take care of this if you made sure to mute the output for a couple of seconds while it is powering up. These things do run hot. I have one of the ones I built for another user back for repair after it was left on with something on top of it. Amb notes on his forum when replying to a user who used his regs in a piece of Bryston equipment that they don't like heat very well. Since the LDO reg is really the only thing on his boards, this must mean that those reg chips don't like heat much. The GB boards were done using 3oz copper, making them about as good of a heatsink as you are going to get from a PCB (and a huge pain to work with).

My heart almost broke. So glad for that last bit.

I think it was a combo effect. I thought I cleaned the drip tray and dump trough after my last brisket, but probably not good enough. The belly was good and fatty, so there may have been more juice than previous runs. And there seemed to be more dust in the pellet bag when I was filling the hopper. So this may have led to it throwing more sparks than normal with the blower. I have sifted pellets previously to reduce dust, not this time. So - I will clean more thoroughly, sift my pellets, and buy less fatty belly (the last one will not happen). On a positive note. After cleaning, I ran it up to 500F and back down, no issues, then smoked a lovely slab of salmon (not pictured). It worked like a charm. So the my thoughts on it just being cosmetic seems to hold out for now. I will pick up some high temp paint to give the open metal a coat. Also as a side note, since I setup fiber internets I didn't put the grill on my network yet. The app would have told me if it got to cold, or in this case too hot. So adding the grill to the network is another task.

I don't do new year resolutions. However, I now have one for 2026. Eat more Korean food.

Shit, Mikey. I've read a few stories about grease fires but that's pretty extreme. Do you think it was just from the belly or was there some built up grease from the grill/smoker not draining properly or something? Regardless of root cause, that sucks.

Was thinking about you, Todd, and your nephew as I spend a few minutes out in the driveway tonight tinkering with the camera. I'm pretty shite at. lunar photography, but still had fun for 10 minutes until I couldn't feel my hands.

Ok, I really like the Royer SF-12 - just need gain. Currently using a MH ULN-2 with 3D card. Now I need to do the recording bit, any suggestions? I assume I will not be able to record directly off the digital outputs at a reasonable price point, so would something like a mixpre-3 ii be a reasonable choice? I suppose I could just use a laptop as well but keeping it small, battery powered and transportable would be handy.

Excellent - thanks! I'm only sorry we have such dick head regulators in our small island, spoiling IMGUR access for the 65 million crammed in to our speck of dirt.

Before I start working topside, I have a question about the onboard regulator vs the AMB. I have both, and given the ability to get it attached, which is preferred? Is it better to just use the AMB and get the heat off the board?

So I wanted some new year pork belly... Loaded up the grilla with three chunks. At about 9pm last night they were hovering around 180 degrees. I was going to give it another hour and give it a check. Well I had walked out to a grease fire happening. Pulled the pork (what was left of it) and put out the small fire. Some cosmetic damage: and three pork briquettes. The middle one might have some salvable pork on the inside. I will deal with that later. I need to clean everything up because I have a slab of salmon to smoke up. Happy New Year! 🥳

Aw, too fucking hip, that's amazing! Yay science and your nephew!

Somewhat ironic - since I'm not in the UK, your post is showing me exactly the same amplifier picture I posted earlier :). I see the problem though and I think it's been brough up before in this forum. I was hoping for Imgur to resolve this, but if it persists and/or spreads I might look for another image host.

personally I set my vpn tunnel location to the USA and then I can see the images... at least until the uk makes vpn tunnels illegal...

As soon as you guys start using IMGUR, we cannot see content in the UK. This is because the UK on-line regulator OFCOM is suing IMGUR as a result of lack of assurance regarding harmful content to minors (AKA under 18!). IMGUR has responded by simply showing a blue screen with "Content not viewable in your region" in large letters. This describes the decision https://www.bbc.co.uk/news/articles/c4gzxv5gy3qo IMGUR images look like this from the UK

Looks fantastic.

We skipped the BEPs this year as the luck thing hasn't worked for the last few. Went with a whole einkorn wheat flatbread with onions, shallots, anaheim peppers, gouda, cheddar, parmigiano, and herbs.
