Believe me, the eye is very, very accurate when it comes to define whether two arms are parallel or even slightly in/out! BUT the black plastic of a record, when in contrast with the alu parts, CAN be misleading! So trust your eye but don't get sick about it alright!
-
Yes, but those awful records are best forgotten! They were generally poor sounding... I have always refused to adjust any of my automatic decks to comply with off-the-norm LPs. Worth a try perhaps!
-
Yes I understand! I love mine too; so much so that I'm selling my beautiful Technics/RB300! Congrats!
-
Opening that can again... not something I'm looking forward doing!

Hi Olly, The inductors are fine. Do you mean the crystal itself could be the cause of the problem? The frequency counter increments fine (displays correctly) but I'm not a processor specialist... Some kind of instability happens somewhere but I can't see it. I wish I knew how to test a processor! Thanks for suggesting this. A new 2MHz Xtal,

No difference, I tried mylar and ceramic. Still stuck at 102.

[quote user="tournedos"] [quote user="chartz"]Yes I did fit a 22µF cap across the new 7805 (out), and a ceramic 100nF (in). [/quote] According to general knowledge on the 78xx regulators (with no specific experience on the BM8000, and I'm not going to argue with Martin if he tells you otherwise for this application), these

Thanks Martin. Yes I did fit a 22µF cap across the new 7805 (out), and a ceramic 100nF (in). All the other caps have been replaced with brand new ones. I now have three Beomasters, the 80's 6000, the 8000 and the 5500. To my ears, the absolute best is undoubtedly the 8000, it is more detailed and has more depth. The runner-up will be the 6000

Hi, The story goes on, and I am more and more puzzled! I finally changed the 7805 regulator (along with caps and the bridge rectifier), because it reacted strangely under strain. Now I am almost sure there's nothing wrong with the processor module, because now I can dial up to 102.5 MHz before the system collapses. Voltage (5V) remains dead stable

Hi, Same analysis here! However I did it differently - perhaps less elegantly - I added a spacer and it works just as well.
