Dave,
I built one on Proto-Board my first try. It was tedious, but worked well. You can build on a breadboard, perf-board or etch your own. Mr. Carlson does not usually do commercially produced boards and the practice is discouraged on Patreon, for obvious reasons. I would not doubt that someone has produced some of these boards, but I do not know of a source myself. -- Michael Lynch Dardanelle, AR

I'm with you, Dave. OSH Park and others have PCBs for dirt cheap these days. No point in fabbing your own. Been there, done that.Jim Ford Sent from my Verizon, Samsung Galaxy smartphone

So then I suspect he does not have gerber files to download? It would be possible to lay it out in CircuitMake/TraxMaker, but if the circuit uses somewhat modern components, then one would have to create macros for them. As I said, I think a minimal of 5 proto boards would be needed. So if the board works, there would be extras. Since it is Paul's i.p. you would not be able to see those extra boards of five of us wanted to make the cap tester. dave

Maybe someone could get permission from Paul to have 5 boards made and share the spare boards?

I have been a member of Paul’s patron since the beginning. Just to be transparent. I have seen this question asked many times. Paul’s response is usually the same. “He strongly recommends that you make the boards using the toner transfer method.” I have done so personally and have learned a staggering amount especially in the QA department having to quality check my own boards. It has also given me a much better understanding of what is really going on. There is a lot of learning building it completely from scratch.

I think the only honorable requirement would be that all parties receiving boards MUST be patrons, and this must also be done quietly/ not too publically.

If the above conditions are met I would think he should not refuse the idea...again just not make it to public.....ie a few friends..... Renée

Making PC boards is not really a trivial task. Toner transfer needs a laser printer and some understanding of the process, regardless of whether or not you use it for an ESR meter or some thing different for a Tektronix rebuild. Toner transfer can best be used on single sided boards, but double sided boards are possible. Requires more understanding and the right tools. The board factories (oshpark and any of the Chinese board factories, for instance) tend to make boards in lots (oshpark is $5 per square inch, but you get 3, gold plated (ENIG) boards. The Chinese factories typically have (IMHO) a 100 mm by 100 mm maximum size, lots of 5 or 10, and very low prices for HASL (Hot air solder leveled) boards. A typical cheap price is 10 boards for $5.00, with about 20 to 25 dollars for shipping.

All varies per manufacturer. They want gerber files, but will give you the algorithms (files) for the CAM manufacturing of their boards from popular files. I use EAGLE (7.7). These boards are silk screened, double sided, plated through holes. Any boards I can make with toner transfer (disassembled the setup, BTW) would be double sided, tin lead plated, NO plated through holes, NO silk screening. It took me a while to get there. I did a LOT of toner transfer boards (laser printer, laminator, special paper) before my designs got too complex for manual layout and toner transfer. There's lots of low cost, low effort PC board techniques. Haven't seen the target project, so I can't comment. There are a number of projects directly related to Tektronix that can use PC boards. I'd suggest test fixtures for the 7CT1N, for example. Feel free to contact me off list if you want further information. Harvey

Hi,

Yes, the current offerings from China and elsewhere on PCBs just make it practically nonsensical to DIY PCBs at home. It was a fantastic feeling when I first ordered my first plated hole, double sided smd PCB from china, complete with solder mask, silkscreen, etc. This would have been out of reach for a hobbyist a decade or two ago. I'm not nostalgic about getting back to etch stuff in ferric chloride, drilling, filing, etc. even though that I even built a compete oscilloscope this way back in the poor university student time :-) I used KiCAD for a lot of stuff now and works like charm. (I have even shared a very simple TekMate 287 daughterboard design with this group) Of course if one needs to make a large non-plated hole simple board, it may be cheaper and you don't end up with 4 additional boards, but taking the cost of the time for this, it still may be better to have it fabricated. Good that you mentioned the 7CT1N, as this has been a long time plan for me to make some fixtures for my 5CT1N, especially seeing the price these are being sold on eBay. I have just started to sketch up some design and look for parts. So I would be gladly helping with coming up with a design. I can do the PCB, but this could be a good group effort as it would be nice to have some 3D printed enclosures for it. Of course it can be simple small PCB with 3 plugs and some zif socket, but why not make it really fancy if we have the knowledge and tools.
