1971-1972, my final year at Leicester UNI via Marconi Radar...

I have always had a _fetish_ for Oscillscopes, RF Spec-Ans', etc - even today and for my final year at the above UNI this was my choice building a 1 inch Scope running from a 12V DC supply. Nearly everything was raided from old TV sets and the tube DH3-91 was bought from an electronics junk shop. The EHT transformer was home wound and supplied around 700V DC for the tube... It is electrically finished but I was unable to finish a front panel for it for the marking.

It was in my loft for 20 odd years and the dual-concentrics were seized and other minor corrosion elsewhere...

Notice the wiring even then!
Also notice those hideous circular power resistors used replacements in the heater lines of valve TV sets of the 60s and earlier.

Note the black electrolytic, added because the original dried out and the PCB was hand ecthed...
