yous wit
i mean across with the red probe at one side of r29 and black probe near vcc- measuring dc
in tat case, you're in big trouble
though, 20V across 0R27 means 74A, means drekload of heat and most likely melting
which means also, I'm doubting that you even did measure that exactly.

yeah probably shouldve been a little more educated before i jumped into this maybe shouldve started with an ACA or something
it's not just soldering
it's staring at goats, as most important
as several mindful Boyz around did very nice Build Guides, so very pretty goats, one can not just learn but also fully immerse in their beauty
now, that's me, finding beauty and elegance in nicely engineered thingies ...... wakoo

im wondering if i should just buy a new parts kit and start over with the amp boards. I should do everything much more correctly with more experience and having read the build guide multiple times now instead of skimming through like i did the first time
why not
but, it'll be wise to post pictures of each phase of build and ask forforgiveness permission to proceed

Or maybe build and F5m first? Save the Aleph Jzm boards for some fixin' down the road? Then you'll eventually have two different amps to swap in/out.

Desoldering and removing ALL the components from the amp boards without proper tools or prior experience is quite a task.
Buying a new Aleph JZM board set with parts, when ready, is probably the best path for a successful build.

My advice, from a complete novice, not a former electronics anything. When I say novice I mean I never owned a soldering iron or a multimeter before my ACA build. Buy a new kit, measure everything, stuff a few components at a time, post pictures, get feedback. Never make an assumption or guess, ask first. Never feel embarrassed asking any questions. You will get very few detractors, the vast majority of the members are patient and willing to help.
I’ve built the ACA, f6, aleph j, bottlehead moreplay, omicron headphone amp. No fires, no shocks no ruined parts because I followed the build guides and asked what I’m sure were terribly ignorant questions.

these are the best, when followed with effort to understand replies
muchmuch better than ignorant errors, made because of shyness
I'm not shy at all, realized with time that it's clever to be stupid 'till the end of time and get all answers I need
I agree 100%. I (of course) have a bias, but I've added emphasis to one thing above that I am reasonably sure would help...
@yarozebob - As a pretty good rule, we're a lighthearted bunch that wants to help. Personally, I know if you take it slowly and follow instructions you'll have a working project. I am curious why you deviated so far from the build guide. You can PM me if you're more comfortable. Did you not find it? Should we make it more prominent on the sales page? Either way, when you're ready to resume, I'll send you over a new kit if you'd like. You cover postage. IMO, trying to repair what you've done would be an impressive commitment. However, if you'll promise to follow the guide... for your second try. I'll send you a new kit.
I purchased along with my Aleph Jzm, the custom case to go with it. Noticing the two LED holes in front panel are extremely small!
Do they make LEDs that tiny? Or do I need to simply drill the backside large enough to fit "normal" LED, like the Zenmod custom Iron Pre chassis LED openings?
Or just glue it over the hole? Seems like I have see power indicator LEDs in tiny holes like this on various electrical devices.

On my homebrew stuff I drill the back of the panel to fit the LED body, and let the light shine through a tiny (or at least smallish) hole in front.
