Default Lernakit Oscilloscope Build Instructions

Its been a while since I was on here, house move, builders etc. A while back there was a thread regarding the British National Radio School Lernakit Scope and I was wondering if anybody managed to find a copy of the build instructions and component list. I have all the other paperwork but not the build stuff. Can anybody help? Thanks.

Hi!

I have the instructions for the B.N.R.E.S. Mk. 2 Transistor Version Oscilloscope and will get them scanned over the next week, but I've never seen anything for the two valve Mk. 1 version.

One or two odd members have said a long time ago that they have the Valve Oscilloscope Assembly instructions but nobody's ever come back with them, and I have never seen them myself!

If I read this thread correctly: https://www.vintage-radio.net/forum/...d.php?p=495894 user Bumblebee has the manuals/instructions for the two valve edition.

I have a copy of the early 2 valve version notes (possibly factory produced) its got internal unit sketches along with semi coloured circuit diagrams and a breakdown discussion of how it works.

Unfortunately its on legal size paper and my first scan hasn't captured it all so I'll try later and post it on here as pdf for anyone who wants it

Hi!

B.N.R.E.S. "Learnakit" Mk. 2 Transistorised Oscilloscope Assembly Notes, first five parts covering Steps 1 to Steps 3!

I used the high-speed ADF scanner at work so unfortunately all the blank pages had to be included as well - these can be deleted with one of the free Online PDF Utilities if not required!

PS!

As I had only a few minutes spare there wasn't time to rename all the attachments I'm afraid!

PPS!

Please note that these are duplicated materials as originally supplied by the B.N.R.E.S. and it's inevitable some of it is going to be a bit furry in places!

Anything that's really too unclear I will redraught on request by PM or message here, as my spare-time permits!

Hi!

Member "Bear2Biker" Paul B has loaned me the Mk. 1 Valve "Learnakit" book to scan, however it's isn't unfortunately a complete one – the Theory Of Operations is all complete, pages 1 to 50 plus the circuit diagram and about 16 of the assembly diagrams covering steps 3 to 8 but none of the Constructional Steps Text is included, so if any other Members have the complete info, please could they dig it out please?

It's very difficult to try and write the missing instructions for Steps 1 and 2 and whatever Steps follow on from Step 9 as I didn't receive Figs. 1 to 6 of the Assembly Instructions or what follows after Fig. 28.

I will get this material scanned and returned to the Member concerned as promptly as I can!
