Hey Noah, the 12k5 shelf connections/components are shown in the attachment. I would check the value of R15.

Thanks Jeff. I'll do that today.

Should I follow the other steps described in the earlier post about the 7k shelf?

Checking continuity on the GH pins?
Removing and checking cap values and such?

And to clarify, I should remove R15 and check its resistance value?

Thanks again

I would check R15 with color codes myself. You can post a close pic of that area if you want and I can tell you. I would also look for a short on one of the 2 caps shown above.

So R15 is indeed a 2.37k resistor.

I'm not sure how to check C26 and C27 for shorts. What is the procedure there?

Thanks Jeff

Okay...
C26 and C27 were both shorted internally.
Soldering in replacements from my 2nd kit now.

Will report.

Thanks!

@jsteiger LC53A up and running.
Thanks for the guidance!

It was 2 shorted caps.
C26 and C27

gonna get back to work making music.

Thanks a million for all the help everyone.

C26 and C27

So both of those 2 caps have their leads shorted internally? That is odd. I have had a few  .0068µF's that folks found shorted but never the .0047µF's. The sad thing is, I am not even sure that I can order these caps again. No one is carrying them in the radial package. I still have a pretty healthy stock of all values on hand though. Let me know what you need and I'll send them out.

Yep. Both of those .0047uf caps beep out on my DMM, leg to leg, out of the pcb.

Thanks Jeff
I better get the next 10 ordered before they're all gone.

Console is starting to look (and sound) real sexy !
CAPI through and through.

Great to hear, that your module is working!

When I recapped my console preamps, a friend sent me some polystyrene caps and said, that I should be careful soldering them in.
They don't like too much heat!
"Be carful soldering these caps in, they can be easily dammaged from very hot soldering iron or prolonged contact with soldering iron. Once you have them in place heat the pcb pad first with the soldering iron and just touch a tiny bit of solder in there to make contact between the pad and the cap lead."
I'm sure you were careful after a few kits, but it's a good advice for someone soldering his first kit!

and @ Jeff,
mouser is still carrying some of the radial polystyrene caps!
they have 0.01uF, 1000pF, 4700pF and 5000pF!
and quite a few axial ones.
I bought them to recap my console EQs!

Yes I saw 4 values but they are going away which sucks  :'(

yeah, my friend also thinks, that they stopped manifacturing polystyrene caps, but then i found the ones from xicon at mouser!
do you think it's just the rest of their stock?
that would be a bummer!

btw i don't know, if the thread already has a picture of your new design…
here are my two lovechilds, just to make sure

 

[Golgoth]

The new design is amazing... Can't wait for stock!

Thanks guys! I am very happy with the rebranding and new look.

We have a batch of LC parts kits nearly sorted. I am waiting on one last cap value to arrive which is due in Tuesday. That said I plan to post them to the store next Wednesday.

 

[jsteiger]

I just added a round of the new Rev B LC53A kits to the store.

;D !!!ORDERD!!!  ;D

Man that was fast!! Thanks! Will ship it out tomorrow.

2nd LC works perfect at first power up.
6 channels of CAPI EQ in the 1608 now.
Looking, and sounding, amazing. All Litz.
I'll post some pics when I fill it

Thanks Jeff

Awesome Noah! Can't wait to see it 

 

[jsteiger]

Rev B build docs have been posted on the support docs page at the store. The first post of this thread has also been modified to reflect the updates.

Cheers! Jeff

Hi Jeff,

I just revised the sorting sheets I had prepared before rev B for my build.

So R5 and R6 have been swapped on the CB board right?

What is it to test during the build on rev B?
Passing audio before installing the filter board I assume (Can I just plug it into my lunchbox with the extension jig for that?).
What else?

Thanks!
