    Well, news can always get better....... i ‘ve gone the extra mile and replaced the old sockets for the two uP IC3/4 and the memory chip as it can only improve things/contacs. i remembered one blog on Beolover, when Rudy discovered the uP board is actually a double-layer board....๐Ÿ™„๐Ÿ˜ก....and being bent and subjected to changing temperatures may show after some 35 years in service...pointing to a healthy level of mistrust in terms of track fractures etc. especially when BM have been subjected

    Further good news: after revisiting the left output amp board I detected a not bonding solder joint on one of the bigger freshly installed capacitors...very hard to see !! i am using a new solder tin with a higher copper content apparently for better and stronger bonding....I wonder ? the unreliable contact issue of the master uP and its old sockets is really crying out for replacing both the uP sockets to tulip style goldplated ones !! the receiver produces sound but I need to revisit the no-load

    Some first better news: the keyboard is back on board after taking IC3 (master uP) out of its socket and deoxited the socket contacts.๐Ÿ™ still unable to adjust the no-load current on the right (working) channel ?? the issue with the left output amp board remains - just the one that is particularly tricky to get to...lovely. now the question is: are the designated darlingtons of that channel likely to be at fault or is the culprit more likely on board #5 i’d go for board #5 as I worked on that

    greetings all, well, I thought I could rest for a while from Beomaster 8000 restoration, but..... do you say NO to a friend in dire straights.....? so, here it goes: this BM came to me with the task of recapping the BM - it hasn’t been done in over 35 years and it wasn’t starting the owner complained. so, I recapped all boards, replaced the two trimmer on the output amp boards, replaced both relays although I was not convinced the original relays were at fault ๐Ÿ™„ i deoxited all pins

  • Re: Beogram CD 6500 starting issues

    Back on the CD player: i revisited the laser current adjustment, which was too low at around 23mV !! also readjusted the metal brace that lifts the CD pug. the player is now starting & playing the disc, however sometimes there is an awful static noise when switching tracks.....? not sure whether this is coincidence but it seems after playing quite a number of discs it suddenly turns off...... i know the player warms up nicely, that is why I want to raise the question of a possible temp failure

  • Re: Beogram CD 6500 starting issues

    Thanks for your concern, but i do not believe this is the case with my laser unit. the machine acts quite erratic - i verified the laser current adjustment as per SM but what is interesting is the fact when a disc is loaded it doesn’t initially spin to read the TOC ? if I press play the disc spins, TOC is red and we are up and running. if I however push the CD loaded tray in by hand the disc performs its initial spin, reading the TOC and the disc starts playing......??? i am totally in the

  • Beogram CD 6500 starting issues

    hi All, my CD6500 won’t perform ! disc is rotating briefly after ‘play’ and then just stops after a few seconds - that’s it ?? I verified the +5V and -6V are present, voltage regulators are fine. the servo boards had all caps replaced incl the “famous” one C2103 (a Vishey replacement) +\- 15V are present.....! some help is badly needed - can anyone assist ? thank you ALF
