Hi, I have an Beomaster 5000 tuner that was made in late 60’s early seventies. The bulbs for the power and stereo beacon are burnt out. I recently purchased new bulbs from beo-parts. The problem is when I put the new lamps in I automatically lose sensitivity when tuning… meaning it almost like I do not have an antenna hooked up and the output volume gets lower also, though once I remove the lamps the tuner works as it should… can anyone assist me in the reasons why this might be occurring. Thanks, John

Are you sure the lamps you have purchased are specifically for the BM5000 tuner? wrong mA rating plays havoc with BM4400 tuners, I dont have a circuit diagram for the BM5000 tuner to hand but do have one somewhere...make sure the lamps are correct (check with Martin AKA Dillen from this site to confirm)

By the way.....the BM5000 is a cracking tuner, there is some evidence that the BBC once held three or four to use for monitoring the strength and quality of the signals transmitted back in the day.

The lamps are correct.
Weak rectifier would be my guess. Wouldn't be a first.

I have a Beomaster 5000 which when it came to me had a replacement rectifier fitted now I come to think about it......
