"Learnakit" DIY Course Oscilloscope!
Hi!
Has anyone got the scan of the original Scope Assembly instructions (not the full set of Course books) for one of those small Black "Learnakit" valved scopes please? (I've got a ball-point pen scrawl of the circuit-diagram, but the assembly of the one I had is an absolute mess!) Chris Williams

Re: "Learnakit" DIY Course Oscilloscope!
Hi Chris
Found this on the net, is this it. It has a good circuit diagram. I don't know anything about these scopes, hope it helps. Regards, S-W http://elektrotanya.com/british_lear.../download.html |

Re: "Learnakit" DIY Course Oscilloscope!
Drifting slightly OT but I have an identical-looking scope (except for front panel colour) but it's transistorised and built quite professionally on pinboard. The internal chassis appears to have cutouts for 2 B9A valve bases. A capacitor bears the date 1981.
I don't suppose anyone has the circuit diagram for that version? Bryan |

Re: "Learnakit" DIY Course Oscilloscope!
I don't know if you still want this Bryan, but the following link has some info on the transistorised version: http://www.eevblog.com/forum/testgea...-oscilloscope/
I have attached the schematic from this site. Regards Dave GW7ONS |
