Thaks i'l look out for a connector but as the mod will be reversible, in the meantime i will try a DIN connector, just to get the unit working!!! cheers RDS

Can we make it a sticky then? Will we be able to upload at any time and keep adding to it? I really feel strongly that we should have it!!! How do we start it?

Primitive, indeed. It's bad luck for me in terms of using the machine, but good to learn how these early versions worked, and even better to know things have improved a lot since those days. Many thanks for this advice. ~Goloh8888

Another thought... Use a multimeter set to its lowest ohms range to see if any of the four connections are connected directly to the chassis

I've just checked the cassette player in my classic car. The colours are as follows:- Red =Power (+12V) Green=Left. Grey=White Black=Speaker Common. Case=Earth (0V ie battery negative).

What has happened to the felts on your machine? It would seem to me that felt changes very little over time so that unless it becomes very contaminated it should last indefinitely. Also, carefully sandpapering the surface will remove any surface dirt and some of the felt. Perhaps the felt over time gets compressed, the surface gets smoother, and the friction goes down? (Normally one would store a machine like this in the STOP position, with...

Hi. Thanks for the info. Most has gone straight over my head but my tame engineer friend will now have a pointer in the right direction. Many thanks. Roger. PS: I just love these little machines. This particular one is identical to my first ever recorder, bought with my first month's wages when I started work (with a little help from my dad....). Pity it's not in quite such good condition though.

The redrawn audio circuit is at:- http://homepage.ntlworld.com/lez/TEA...CUITS_WIP2.JPG When I get time I hope to add another section to the previous word document covering the Logic Board, control and power supplies. Hope there are not any mistakes, a lot was done though into the very late hours. Les

Hello Ricard, Yes, '.. a plastic screw on the later versions), which adjusts the distance that the pulley is lifted away from the reel tables' is the one that I was referring to. Regards, Andy

They probably won't have failed. But in your first post, you refer to them as 6V bulbs. If you put 6V across them, you won't see anything because they need about 90V (current-limited). To test them, connect a resistor 47kΩ to 220kΩ in series, and connect across the HT supply. Or even the 240V AC mains.
