Older (and Wiser) by Lizzy McAlpine (2024) https://album.link/wgwhc8wnv2w2n Example: I really appreciate this release. At Just over an hour and 19 total tracks this explores a lot of things that she wants to say. I appreciate the production, close mic work like normal, but I was surprised at least 3 times by the choices made, and I am not surprised easily by music.

What, no "bucha" bar? That is way gnarly dude. So Arkansas 1992 dude.

I’ll just buy at Best Buy and return the loser 🤷♂️

If you want to go down the 'Merican route (Note the dB levels in the "Noise Levels" section - testing with a sound level meter - 3:45 - 4:50) via: The folks on reddit suggest getting a demo of your candidate machines to aid the decision process. "Have you gone to a William Sonoma or a Sur La Tab to sample and talk with them about the various options?" via: But that may be easier said than done in Little Rock, AR

I think I want a super automatic for the store. Thinking a Jura J8. What say y'all?

Is Pakistan full of crazy people? Like Palenstine, you only hear of them in traditional media when they're fed up and the controlling interest, of course, controls the narrative. I mean think about Partition.

Looks like ground zero for nuclear war is now India and Pakistan. This has been brewing for a long time, and Pakistan is pretty much full of crazy people. The government is unstable. The chance of Them firing off the big one looks more likely every day. Let's hope cooler heads prevail.

Sorry you weren’t feeling well, Steve. I’ve had COVID twice and it really kicked my ass the first time. Glad you are doing better.

Re-reading a chunk of Isaac Asimov's stuff - Foundation series, Robot yarns etc. The Foundation trilogy was published in 1951-3 and have really stood the test of time. I became curious how Asimov died. Turned out a too early 72. But in his early 60's he had a triple heart bypass (in 1983), and was given a blood transfusion tainted with AIDS - and that was what killed him in due course. Same thing happed to the tennis player Arthur Ashe aged 49 - again following heart bypass surgery in 1983.

JoaMat always helps. I appreciate the input regarding the 2N3904. I've been considering a modification to handle higher output current more safely. Would it be feasible to add an IXTP08N100D2 (Depletion Mode MOSFET) before the C2M1000170D to serve as a hardware current limiter? Drain of IXTP08N100D2 connects to the Source of C2M1000170D (main current path). Source of IXTP08N100D2 connects to a sense resistor Rs, then to GND. Gate of IXTP08N100D2 is tied to GND (0V) or through a simple RC filter to mitigate noise. The current limit would then be: I = Vgs(th)/Rs. Would this be a viable approach to implement a basic current limiter before the C2M1000170D, or would there be better alternatives?

2n3904 does the same thing. Can be removed. Anyhow it won’t protect you from sudden shorts. -
MLA, Thank you for the reference. Since the C2M1000170d is ending the life cycle, I don`t want to trash them.😅 I may just go with the universal power supply which was used on Megatron before. 2n3904 current limiters needed to remove for the universal supply. I`m wondering if the 2n3904s in GRHV do the same purpose? if yes, can we remove them to increase current? The single universal power supply worked fine on my previous Megatron build(Each El34 draw about 27ma). And I assumed each 300B draw 33mA as Kevin mentioned it is the sweet point for 300B. Don`t know if I calculate it correctly.

Back at work today, feeling way better.

Regarding you last question, I'm using GRHV in that role so I would say it's doable, but in addition to adjusting the current limiting resistor you need to put some protective measures in place; otherwise there is a good chance the SicFet will blow up during startup (I killed 4 before understanding the problem ). See SimmConn's post for great advice:

Finally, I have time to hand in the Megatron XL. Having some questions here. What`s a decent static plate current and voltage for 300B? For the tube rectified power supplies, can we do a solid-state rectifier instead of the GZ34/EZ81? Assumed we have other soft-start high-voltage circuits populated. I'm wondering if it's possible to use the Golden Reference HV supply to provide ±450for XL. Does anyone know if the current capability is sufficient? I'm concerned the total load might be too much for this PSU.

Back when Kenny was cool. Can anyone point out another famous band member? He was in many well known movies including Slingblade. Also made multiple appearances on Home Improvement.

hehe - that is why it was funny... :} I'm a funny guy - just ask me... To which my normal reply is - "I'm funny Damn It!"

Uhm, what? That was 1976 my friend.
