[BUILD] 1176LN Rev D DIY

[rokus666]

Pad 20 gives me -6.9 V

I don't know what to do anymore as I don't want to keep blowing fuses (running out)  ;D

Pad 20 plugged in only gives you the voltage drop?
Check the solder connection for the wire going to the ratio board, if it is just plugged into the ratio board something weird is going on there

Finished my first rev d 1176 today! Worked right outta the gate. Calibrated with no problem.
All of my 3707 measured between 194-210 hfe. I used 5088 in q7-10.
This compressor sounds great!
Thanks to mnats and Hairball.

Ed,

Congratulations.

Would you post a couple of pictures of the build for those of us about to start?

Thanks

I wish I could say that for mine 

I am still trying to figure out where the problem is coming from and it seems I am not knowledgeable enough to figure out the exact spot.

Learning...

Lucky you

Ok, fuses blowing like crazy.

I disconnected the following:

I disconnected pads 20, 18, 22, 21, 19

Also, unsoldered pad 6 from the ratio board

Measuring the voltages on Pads:
20  -9.72
18  -0.254
22  0.7
21  1.35
19  1.057

I found the faulty connection on the terminal PAD 21 (bad solder)

Lets give it a shot now...

Ok, fuses blowing like crazy.

Fitting a fuse with the correct value instead might not be the worst idea....

Hm, I am using 250V 250mA

I have just blew the last fuse when Gray (pad 21 was connected)

Without quoting your mains voltages (why can't people be bothered to put a location in their profile when asking an intercontinental forum) and type and VA-rating of your mains transformer, this number doesn't say that much and BTW is probably missing the fusing characteristic 250mA/x (x might be 'ff','f',' ', 'mt','t').

Because, that would make things easier.... : :

can you post a sharper image so I can see?

Hi!

ask the following numerical capacitor, change correct?

C8 = (MKP2-.15/100/5) change (MKP2.15/100/10A)

C9=(MKP2-.22/100/5) change (MKS2.22/100/10)

C22=(MKS2-.22/63/10)  change (MKP2-.022/250/10)

C27= (MKP2-.022/100/5) change  (MKS2.22/100/10)

Thx!

Hi there folks!

I've just ordered all the components in the BOM except for one that are not available for 16 weeks. This is the component : http://se.mouser.com/Search/ProductDetail.aspx?R=286-240-RCvirtualkey21980000virtualkey286-240-RC

I'm wondering if there is a component that will do the same job or if I'm going to have to wait for 16 weeks before I can start building.


Thank you people!

I think this one will work, correct me if I am wrong!

Hi!

Vishay/Dale CP0005240R0JB14 Can replace Xicon 286-240RC ?

After carefully soldering R44 and R86, I get 0 ohm continuity between the center and right pad with solder side facing upward.  I was checking for a solder bridge because these are smaller pads. 

I think that this, 0 Ohm continuity is confirmed by the schematic because the one leg and the wiper are connected. 

Am I correct, would someone confirm what I read as per the schematic.

 

Thanks for your response

Hi!

Just wondering'.

Since I live in Sweden our mains are 240 volts i need another fuse than the one that's included in the BOM for the rev D. The fuse in the BOM is 5 x 22 mm. The size of the one that I'm looking at right now is 5 x 20 mm.

Is it of the utmost importance that I find a fuse that has the same size, or i'm I cool?


Thanks a lot folks!

Since I live in Sweden

maybe add this to your profile.

our mains are 240 volts

Sometimes. AC mains isn't a constant. Will be 230VAC within europe and might vary in range +/-10%, depending on location or time of day.

i need another fuse than the one that's included in the BOM for the rev D. The fuse in the BOM is 5 x 22 mm. The size of the one that I'm looking at right now is 5 x 20 mm.

diameter/length 5x20mm is a common european standard dimension size. (you could still get a hold on ancient 5x25mm sized ones, the 5x22mm from the BOM might be a typo)

Is it of the utmost importance that I find a fuse that has the same size, or i'm I cool?

The datasheet of your fuseholder or fused IEC inlet will know it exactly.
(Fuse rating and fusing characteristic would have been the expected question, that couldn't be answered until you'd say whats your mains transformer type and VA rating.)
