BASF 9301 radio cassette 1973
I am working on a battered version of this - any idea who made it? (I doubt BASF had any electronics production lines). It is quite an original design, all metal and rather convoluted - to replace the belts you have to remove a plate which holds both spool tables, the hubs of which protrude through two holes cut into the upper chassis. Motion sensing is done via a sort of wiper/wafer switch affair. It might be ITT or similar, I suppose.
I'm also after a schematic. Someone has been inside this and 'had a stab'. I've replaced the belts and revived the radio, but the problem now is some short in the cassette area, possibly the switching/stop circuit etc. This does seem to function in that when you press the transport buttons you get a loud low hum and it stops prematurely and flips the cassette door open! This thing is full of germanium transistors, which does not help.

Re: BASF 9301 radio cassette 1973
It does have an ITT look to it.

Re: BASF 9301 radio cassette 1973
It could be an ITT but I have a Sharp radio with similar styling, particularly the tuning knob with the recessed front.
Hope that helps. Andy

Re: BASF 9301 radio cassette 1973
I had one of these when the first came out, circa 1971, to exploit BASF's new Cr02 tape. A really lovely radio and cassette player. They were made in Japan as far as I can remember; I was told the cassette unit was made by Sony, but how accurate that was is another matter! My cassette eventually failed (the broken belt didn't help) and it ended up on a skip... alas.
I think I still have the manual, but don't recall seeing a circuit diagram with it. If you do get it working properly, you won't be disappointed. Merry Chrimbo! Barry |

Re: BASF 9301 radio cassette 1973
Could the deck be Philips? I think they used the wiper/pcb wheel stop detector.

Re: BASF 9301 radio cassette 1973
I'd say it definitely isn't a Philips. Quirky yes - like Philips, but in a different way (if that makes sense!)
Can't say I blame you for skipping it back then Barry - this deck is the most absurd repair-unfriendly design I've seen, and I've seen a few. A simple belt change took me over an hour! And even then I 'cheated' by not fully removing the motion circuit as access was just possible with it in situ. Anyway, will keep probing.

Re: BASF 9301 radio cassette 1973
Hi Ben,
Yes, I remember well by that sinking feeling when I came to change the belt. You'll be pleased to know then that I haven't found the manual or circuit diagram - pity really, as they were a very nice unit. Merry Chrimbo! Barry |

Re: BASF 9301 radio cassette 1973
It is AIWA TPR-210. Most BASF products came from AIWA. The biggest problem is the textile belt for autostop :-(. I have threw the thing away 20 years ago, but I still remember it, as it was my first radio-recorder for chrome tapes.

Re: BASF 9301 radio cassette 1973
Yes, but these are just details. It is a slightly modified AIWA TPR-210 manufactured by AIWA for BASF. Check the top panel or the left side panel with connectors. These are exactly the same.

Re: BASF 9301 radio cassette 1973
Hmmm... Did other brands use textile belts as well? I remember an old Crown deck using a textile belt. It could have been made by Aiwa, of course.

Re: BASF 9301 radio cassette 1973
Thanks for the info! So, it seems it is an AIWA.
I've put this one on the back burner for now, but will update with progress as and when.
