I was worried about connecting them charged up?! I was afraid that at best would be big snap! Sound, that might zap circuit upon hookup? 😞

Blue Glow Electronics had a nice video years ago detailing the build of a discharge wand for capacitors.
BTW, even if you have charged up a supply and don’t have bleeders installed, it will eventually discharge….it just takes a while. You should always check with your volt meter prior to messing with it or connecting it to your favorite main amp circuit. But honestly, this is all about safety, so measure with your DMM and then discharge the capacitor. Bleeders are for safety and are installed for that reason.
I even measure the voltage of capacitors I receive in the mail. Especially large caps (like 47000 microfarads). In cold weather, you’ll notice they have some charge. I discharge them with a resistor and THEN solder them to my power supply board.
I have often thought WHO is building the F5m. Are they seasoned builders? Are they diy newbies with a few amps under their belt? Or are they absolute newbies who have never built a linear power supply before? Probably all of the above. Hence, the need for 6L6’s excellent guides which will provide these safety details I am sure.

Ya let's not hook anything up that's still holding a charge. I like bleeders right at the PS caps for safety for those times when I'm changing things out and doing upgrades.
Behold this ultra high end 227 ohms half automatic Cap Discharger Deluxe. 🙂
Oh…for all those reading…here is a message from our sponsor:

Well, here is mine in its temporary chassis until smaller ones become available.
Well, there has been some muttering about a higher output version....never have too much heatsink.

These massive PEH169's I just received came like this... I'm getting ready to switch my power supply over to a config I read about on the CRC vs. CLC thread. If it works out it will be the foundation of any future projects coming down the pipe for awhile. And it will power this F5m first.
As far as builders, I'm sure it will be a broad mix of seasoned guys, greenhorns, and everyone in between. I think there's something in it for everybody. But particularly the new guys. It should be very easy to build and get going for most folks.

A F5 minimalist turbo? 🤣
Kind of reminds me about what pa said in his F5T article.

besides, have no interest in making intergalactic concert
I mean, I've got tired of destroying planets

Is anyone planning on building F5m in Dual Mono?
Is it possible this kit power supply will be made available separately? If not can we buy 2 Essentials Kits?
Or, for some time will the Store power supply be the best way to achieve it?
Laying out to cut chassis now and deciding if it is just best to build as is.
Thanks, H.

H,
I think that‘s a good question for the diyaudiostore people. But from an electronic standpoint, you can totally use two F5m PS boards if you want to. You can use a single 300VA transformer or go crazy with (2) 200VA transformers for example. And you can just use the V3 Universal Supply Board if you want.
Your choice. DIY World is YOUR Oyster.
My F5m will go in my NPXP, which houses a single 800VA Toroidy. The reason I chose that is so I don’t ask the ‘What If’ question. It’s just an example when a builder goes bat-$hit crazy. You don’t have to 😉 🤔🤓💪.

If there are plans for the PSU to be made separately, I haven't heard it.
It's a great idea, and likely will be some day, but don't hold your breath waiting for it to be offered alone.

It's trivial to offer just the supply. Management chose to bundle it, but if people ask for it...
It's too good to not use on other projects from the store. Or in this case D/M.
I'll be the first to ask for it.
Thanks, H.
