This looks like an cheap and easy root not sure if this was mentioned before

Yip that is the cheap and easy route. Something I do not want to do as I want to keep as close to original on this project. Thanks in any case for the heads up!!

Quad 303 restoration - Regulator and output board PCB
« Reply #256 on: July 22, 2019, 10:13:56 PM »
Out of the blue one of our fellow forumites contacted me and offered to help me redraw the PCBs electronically in CAD to obtain the required Gerber files. I am ever so thankful.

We are working on the regulator board at the moment and taking it small steps at a time to make sure the end product will be as close as possible to the original.

More news on this journey later!

I asked @Family_Dog to do a post insertion in the first post of this thread. Here I am listing and thanking everyone who has contributed to the project. Let me know if I have forgotten to add your name!

You could send me the top cover of the tuner and I'll pop around to a Ceracote specialist. Might be able to match the color pretty close which will see me ordering a small 4oz tester from the States. These can be had in an air dry version which is different to the oven cure type I use. This will of course mean spraying all the covers just to be sure the color matches perfectly. Only caveat being the front panels being printed so I would not think those should be done. Worth a try, as ceracote simulates closely the pearlescent appearance of the Quad paint.

I'll not charge for the spraying if an option and a suitable color match can be found in their range. Guaranteed not to wipe off with ANY type of thinner or acetone  :thumbs:

That sounds interesting, what is ceracote I've never heard of it before?

Thanks @Schalk I will look into this for sure! Let me just get my daily life back in order. Had a run of not so good things happening the last few weeks.

Just to say I admire your diligence and patience in this process. I would have freaked by now - too long for me.

Even though I have subscribed to the 2 threads I have received zero notifications.....  Damn.

Herman, If you need boards done, I can help with home-made PCBs. If you can send me a PDF or a graphics file I can do them. Single sided only, please!

I do everything manually so I cant do fancy holes or slots etc. No silkscreen layer either...

I spray the tracks with Kantakt SK10 which makes soldering a breeze.

Surprised to hear about Bosco, they have made thousands of PCBs for me in the past, with only 3 bad boards. But their attitude can be absolutely atrocious sometimes.

Here is a link to a project I made the PCBs for.

Hi @peterc sorry to hear you missed out on some of the fun we have had here!

If you can be of assistance, it will be great. Another forumite is redoing the PCBs in gerber format. I am behind in my tasks regarding this and he is waiting for me!

PM me your details then I will be in touch!

Thanks again. :dop:

Hi Herman...

No rush!!!  When things have settled down and you're ready...  I did however find that piece of phenolic PCB stashed away in the depths of  :angrywife: nightmare - my workroom...  It is double- sided copper though.  I'm sure we can get it smooth and polished on the top side once copper is etched off.

Thanks for the heads up Lance. I have opened the files you have sent and will compare them tonight.
