The speaker chassis also carries the output transformer. Connecting an ohm-meter across the transformer primary tags, protruding through the cloth, gave a good reading and I could hear the speaker produce little cracks of sound when I connected and disconnected the meter. The first selfmade sounds from the speaker for years. Little crackling sounds

Thanks Andy, but it's quite true actually. There's really nothing more annoying than finding out that you could have fixed a certain fault if it hadn't been for a previous repairers failed attempt. Like in this set with the potentiometer missing. If it was still in the set, albeit defective, I could have used it as a reference or maybe even

I couldn't agree more regarding saving that odd one. I did notice the odd dimples on several occasions but never saw one with a fifth pin. If someone knows about it, it must be Frede. He's far better with them olde SP's than I. Martin

The BM8000 won't act as a clock radio. It doesn't have the clock and timer functions. Martin

These are all repairs that are legal in my opinion, since they were performed while the radio was still in daily use and it was done to keep the radio going. Noone imagined that it would still be around today and if it wasn't for the above repairs, it probably wouldn't have been. Any repairs done to the radio today, now beeing a collectors piece

Well, back on track and eager to move on so today I took apart my own Beolit 39 (chassis no 45105) to compare circuits and components. It seems that my Beolit 39 is pretty much original apart from a few things; One dropper resistor has been replaced at some point, now sitting on a tag strip fastened under one of the nuts on the IF can's screws,

Bill, The motor we talk about is the one for the platter. It will need a good acid-free oil (sewing-machine oil) or similar to it's bronze bearings. Isopropanol (tapehead cleaner) will clean off mote of the old lubricants. Martin

A cap kit is available for the BM2400 amd I can also help you with the rectifier if needed. What's wrong with the other things, you mentioned ? Martin
-
Check the motor by tapping it as I described above. If faulty, repair the motor. New motors are practically impossible to find and their lubricants will have dried out as well. Martin
-
Yep. It can be the motor itself. You can confirm this by tapping the motor gently with the handle of a screwdriver or similar while it runs and listen for speed changes. Due to its nature, piano or violin music is especially good for checking this. The motor will need dismounting, taking apart and lubricating. It can be done if you are careful. Finally
