I am trying to recreate the original Pre-Amp PCB for the BeoGram 1000.
So far, I have the images of the copper traces, including a drawing of the placement of the components and the specs of those. Now I only need to know the exact dimensions of the original Pre-Amp PCB board.
Question
Who can help me find the dimensions. In the picture below I have marked the dimensions I am looking for: A – E.6 August 2022 at 17:32 #36653Dimensions all mm.
6 August 2022 at 18:23 #36654THIS IS GOOD BEOWORLD !!!
6 August 2022 at 18:29 #36655This is perfect information, thanks so much !!!
I will start to re-produce the original BeoGram RIAA preamp.
Fantastic!
8 August 2022 at 18:11 #36656At the moment I am in preparation of making the PCB. My first step is to get the copper traces on a board.
Therefor I have to position and size the image of the copper traces perfectly. I have that picture (see picture below), but it has no outer/PCB border lines, so I have to find out how to size and position this image. (Obviously to get size and proportion equal to the original PCB)
Questions
- Does anyone have such picture of the copper traces pattern, including outside/PCB border lines?
- @Mexking: do you have a picture of the bottom side of the pre-amp board?

8 August 2022 at 21:36 #36658Thanks for sending the bottom view picture!
Yes, I am aware that my trace image has to be mirrored.Question
The board side that sticks into the slot (so where the 8 tracks in a row are), has 8 notches.
Can you please let me know how deep they are?I think they are a little less deep than the 6mm notch on the other side of the board.
8 August 2022 at 23:39 #36659Notches 2.5 mm
9 August 2022 at 07:57 #36660In fact the small PCB in the Beogram sans phono board has the same notches. Just remove it to see!
