Thanks for all your work on this Graham. That battery contact design isn’t something I would expect to see in a cheap toy let alone in what was a top end Japanese made Panasonic!
I saw a similarly dodgy point-contact power supply arrangement on a Sony ICF-M750L. Again a bit of a surprise given the expectations (and experience) of quality for that brand.
E pops up now and again when switching it on. I give it a gentle tap and then it comes on. Maybe it's because it's old. I have been advised that it is tempromental thus it needs to be handled with care. Like us all nowadays. I have a set in top condition and I am proud to own it. Many thanks to Graham for the hardware. Thanks to Tim for selling it to me for a bargain price. 😀
I just dug this receiver out of a drawer, and it hasn't been used in decades. Fresh batteries and it works perfectly. I recall listening to when the Berlin Wall came down on SW back when I was using it. There is actually one thing not working, and that is the "Time Set". Pushing it does absolutely nothing. Thoughts on what that might be?
@@Radiocruncher I am pretty sure they are carbon. I have a few buttons that need cleaning, but not sure how to get at them. Looks like a complete disassembly is required. Any Comments on doing this.
The tiny frequency encoder is a mechanical contact point interrupter. I had a broken b65 and took out cube. Drilling a super tiny hole into bottom let me spray Liquid Gold Cleaner inside. It worked quite well. BUT its so small a error could destroy it. Caution needed. The encoder from B45 works also. Part not available anywhere.
please tell me the same problem is present on it as on Sony receivers? dry out Capacitors need to be changed over time, or is there no such problem on Panasonic?
Hi. Electrolytic capacitors do have a limited lifetime. The better manufacturers used higher quality components which tend to last longer but as soon as problems start then usually it’s down to failing capacitors
My Sangean ATS909x has a weak battery spring, just a strip that doesn’t have as much tension as it should. Also the encoder skips around at times. The keypad has similarities to these Sangean too. Hopefully the cap and transistor are the last bits it needs. Remember kids, always double check the polarity.
I'm surprised that Panacronic would make such a crappy battery connection. Well you obviously fixed it a while ago and it must of continued to work :-D
I have one too and I am also surprised at how bad this design is! This was a set that cost around £180 when it came out in the UK. Mind you, when it works it is up there with the legendary 2001D, a set that you are all too familiar with!
@@Radiocruncher Hi again. My 65 can play up too. I make sure that batteries are fully charged and I try to keep it on for a while. Its worth remembering that these sets were not made to last as long as they have. However, It's a favourite of mine and its younger brother the B45 is particularly good on MW. It's worth looking out for one for yourself. 73 and GDX
Hi Jim. Yes I was impressed with it and am tempted to pick one up for myself. Trouble is I like the Sony radios too much and need to move a few out to make room. All the best Graham
Bought a Panasonic RF-B40, never managed to get the LCD work properly. Besides other issues inside the unit. Seller tricked me in buying garbage. Beware buying a RF-B40, LCD is happy to fail.

Strange Lee. Almost seems like a dry joint somewhere. They do seem to be a bit temperamental though. Cheers Graham
@Radiocruncher yeah I've got a few dry joints too. Lol, cod liver oil helps I'm told.
🤣🤣 I know the feeling Lee.
Excellent presentation video Graham. Hopefully when sorted be a nice set
It’s all done Les and back with its new owner
Excellent Graham sorry I'm slow ha. Thanks Graham

I can’t remember what the keypad switches were. If they are carbon then it could need cleaning. If it’s a tactile switch it will need changing

I believe I stripped the encoder and cleaned it

Hello Graham, where can I get a clear pdf service manual for this model? Because the one on elektrotanya is so bad.
I think the one I was using was the same. If you can get someone to scan an original that would be best
I the the original service manual, is there any thing I can look up for you.

Yes this more modern stuff isn’t built like it was Wenlock. You should be able to strip the encoder and clean it which will stop the skipping

Hi Harvey. Yes it was working well but the battery design isn’t great

Hi Jim. Thanks for the info. Does yours play up as well? I was surprised at how good it was. The 2001D is hard to beat though

Terrible basic design flaws for an upmarket receiver, good luck Graham
Thanks Mike. Yes I was surprised they had done it like that

Strange Dorf. Does the LCD not display or are you missing segments? Sorry you were tricked though
@@Radiocruncher Yes, all upper segments are missing. Cleaning the zebra strip and pushing the panel did not help. Antenna is ok :)
That would have been my suggestion Dorf. Can you replace the zebra strips?
@@Radiocruncher Hello,
it won't be the zebra strip, because when I intentionally misalign the LCD, the top segments never light up. LCD is shot.
That's a shame. If i come across a scrap one I will let you know
