Hi everyone, I am looking for advice on where to troubleshoot the issue.
Got the BM2400 fully recapped, current trimmers changed and adjusted to 15mv, rectifier changed.
Phono and Tape inputs sounds perfect, but no luck with radio. All the radio presets are completely silent not even a white noise.
Does anyone have idea for a reason it might be happening?
Thank you in advance,
Vitaly
Does the two tuning discriminator lamps indicate when you tune pass a strong station (even if nothing can be heard)?
Did you replace the front panel lamps? And if you did, - are you sure you fitted correct spec lamps?

Hi Martin,
Thank you for your interest.
All the lamps are original and working, Tuning indicators are both constantly lit bright no matter of tuning.
Vitaly
That points to a problem in the frontend or the IF stages.
Check the power supplied to those circuits.
Also check that the connectors to the tonecontrol and tuning board is correctly seated and their leads don't short.
Finally, replace the IC1 (MC1355PQ or similar).

Thank you very much for your support Martin, finally replaced IC1 and it is tuning again!!!
Thank you again and gods bless you!
