The Holy Grail Follower Output Stage

I am happy to correct the board myself too. Thank you for all the work you’ve done for us.

I'm happy with correcting the board myself,thanks.

I‘m not ok with you spending many hours doing the correction for us.
I‘m fine with either DIY the correction, as well as with a new, corrected board for a pugno di dollari more (which won‘t happen as the replys indicate).

 

[asanden]

Fine with the correction, thanks

 

[von Ah]

No problem making the change to the existing board. As a backup, how about offering the Gerber files to participants, as well?
Thanks for all your efforts!

 

[lhquam]

Unfortunately, I do not have Gerber files with the correction. My existing PCB layout tools (ExpressPCB and Gerbv) do not include a way for me to edit or produce the Gerber files.

 

[lhquam]

I managed to directly edit the Gerber bottom layer file using a text editor. This is the needed correction. I will put together a zip file for collection of layers.

The poll has closed. I decided to do the easy part of the repair on all 100 PCBs. I used a 2mm flat end mill in a drill press to cut the trace. (It only took about 1 hr.) The PCB recipients will need to add a wire, as shown in the first image of post #190, after the components have been soldered into place.

Definitely a faster method than scrape, scrape, scrape, scrape and cut.

Nice fix lhquam

Also, happy camper with the jumper fix. Thank you!

I would pay for the Gerber and have fixed boards made.

 

[lhquam]

Here are Gerbers for free. There are two zip files. The only differences are the file extensions used for the layers. Some PCB fab houses expect different extensions.

Would you like us to send the funds based on the spread sheet?

Hi @lhquam

Thanks for the list.

Are the shipping fees of $26 usd accurate, I’m finding it odd that it’s cheaper to send your package to Australia and Europe at $22…Canada and US are neighbours after all. Thanks.

It’s likely the Canadian side pushing up the cost. I sent a tonearm lifter (featherweight) in a bubblepack (also featherweight) from Toronto to Montreal - $14.00. Compare that to boards & FETS at $6.00 within the US. Ouch!

Paypal payment sent with shipping details. Sent a PM with address and phone details.

Also, it might be a good idea to post the actual schematic that matches the pcb, with any adjustment details, thanks.
