BeoGram 1000: alternative RIAA PreAmp ?

33 replies
I have a BeoGram 1000 without PreAmp. I have been looking for the optional PreAmp PCB, but it is hard to find or too expensive. Therefor I am would like to put in a PreAmp board myself. There is enough space inside to do that. Questions:
  • Does anyone have experience with an alternative PreAmp for the BeoGram 1000?
  • Is there any PreAmp PCB product to be recommended?
  • Do I have to take into account which SP will be used? (maybe for different output voltages)

I had one built into a 1200 when I bought it second hand - i worked ok but the volume can be a little low for the SP pickup. There are loads of modules around but I ended up using it with an external amp with variable output. My main concern is that you don't know how it's good it's going to be until you build it. Also you have to build in some sort of power supply, which means adding a transformer and other bits into the cabinet - all of which increase the chances of hum. I'd also be interested though if someone has built one in and it works well.

Aïe, Aïe, Aïe, RIAA's… Between the cheap Chineses, the expensive ones, the not so convenient and those who should but don't and on top of that the dark shadow of the "not that audiophile" ones that may ruin the rendering of your expensive MMC. It's a real nightmare. When you add the grounding problems and even worse, the need to board it in the cabinet. That said I don't understand why nobody recreated the B&O RIAA preamp the was optional with some Beograms: Wasn't it made of common components?

Maybe Dillen has a solution?

Thanks all for your responses and contributions! @Matador I have been questioning that myself too. If I look at pictures of the pre-amp board, it seems it is not unthinkable to re-make it. Even in the same look & lay-out as the original. It even makes me wonder if maybe someone did that ... (?)   @premiumverum That's a good suggestion! I will check with Dillen.

Now you can do it yourself ?

@Chartz Thanks very much for sharing these pictures! That makes it a lot easier to try to make one myself!   Question Since I do not have a pre-amp board at hand, do you have the outside dimensions of the PCB?

Hi, I don’t remember but you can find them by looking where it is supposed to be seated inside the Beogram, right?
Jacques
That is a way of course. Measuring the slot size, and calculating the other dimensions from there. Maybe I will post a seperate question for measurements. I guess someone on the forum will have a board, to measure all sizes. If I find those, I will post here what it is. Thnx
