Hello, I am new here. I have loved HiFi all my life and have various set ups. This started in the mid seventies when my father bought a Beogram 1202 and Beomaster 901. I was lucky enough to be given the 901 as a teenager and it served me well until replaced with something more powerful. Recently, I came across a 1202 and fell in love again. I bought it. Then a 1203, and a 3000, well one's never enough. I have those up and running and sounding sweet. This week I have bought a Beomaster 3000-2 to further complete my set up ( also bought a Beomaster 901, due to arrive next week). Having just found this forum, I am pleased to join up with other enthusiasts.
So to my questions: Having had the Beomaster up and running, all sounds sweet on a line level input into the Tape input and Phono 2 and the tuner sounds fine, However, when i connect my deck into Phono 1, there is little volume and only one channel. Occasionally the channel that does sort of work bursts into life with a surge of volume. I have taken it apart and all looks good physically. Hence, I am assuming I have pre-amplifier trouble. I think I have two options, try to fix the pre amp, or replace the board.
If I replace the board, is it only a board from a 3000-2 that will fit, or did B&O use a common pre-amp board across a number of models?
To diagnose the board I have limited tools, a DMM and a soldering iron. Are there any common problems with these I can identify with a DMM? or, is there an obvious component to change? I guess I should be looking to re-cap this anyway, can that be the cause of some of my issues?
Another question, whilst the tuner appears to function well, I can't use the slider to tune. The cord is not wound around the pin on the slider. Are there any tips as to how to sort this. It is too tight to form a loop and if i take it off the main pulley I am worried that I won't be able to get it back on. If I do manage this, how do you align the front scale with real frequency (fix it at one extreme of travel?)
Any tips and help welcome.
Hi,
I just recently repaired the phono input of one of my Beocenter 9500s.
As you guessed it was a capacitor.
Have a look here:

Your amplifier is probably different but it could easily a cap issue.
Especially lok at the black ROE once, because they don't age wel.Desolder them an meassuare if they are short.
Kind regards,Wolfgang
Have you tried exercising the trimmers that adjust the volume level of the phono 1 input?
