to be absolutely honest, I simply bridged the relay contacts on the muting relays...

Marginal RF Instability on Beolab 150

in Imported Content (Unmapped) · Oct 12, 2018 13:56 GMT

Hi Martin, thanks for the reply... It did puzzle me a bit, as I had always thought the Zobel network was there to help deal with capacitive loading such as electrostatic speakers... In any event, as the amp was fully dis…

Hi Nick, as you suggested, I did a complete recap & trimpot replacement on the Beolab 150s, and discovered that the easiest way to work on them was to desolder all the power devices and remove the PCB... Once I had done …

Hi Nick.... thanks for your prompt response... You could very well be right about recapping... I shall make my way down that road... Tony

Hi all... I have a Beolab 150 amplifier, long overdue for replacement trimmer potentiometers. They have now been replaced, but when I had a look on the scope, I can see RF oscillation at around 2MHz. This instability is …

Beomaster 6000 refurbishment

Thanks once again Martin... That did indeed fix the problem... As I am the nervous type, I linked P31/3 to P34/3, and P32/3 to P34/2 temporarily, and this restored normal operation on the bench supply... You are right th…

I am in the process of refurbishing a BM6000... Amongst other things (such as 7-seg displays etc), I have recapped the Power Supply PCB, remembering to link the two pins of 'C1', and also the Power Amp PCB along with fit…

BM5500 real time clock not running with power off

Thanks Martin for your suggestions... The storage at power down was my own fault... The battery works better when it is the right way round... I have replaced the four small caps in the power supply as you recommended an…

BM5500 real time clock not running with power off

I am being a bit stupid here... just checked out PCD8751, and it is just a small EEPROM, and has no real time clock, so little wonder that the CLOCK has to be set every time the 5500 is powered up on mains... This still …

Hi All... this is my first posting, so apologies if I don't get it right... I have a BM5500 that would not bring on the STANDBY LED at power on... It turned out that the lithium 3v battery had expired, exuding fumes that…
