Thanks for reading the thread and for your insightful response and the interesting links Nick. Hadn't realised how far back the design went, or the use of a lamp as a stabiliser. Some time back I built a PW L/C bridge which used a little wire-ended lamp, but the bridge stopped working and I need to take a look at it. I think the IC may have failed. (I've got spare but can't recall which it is).
As to the box, the mahogany was the end if a plank used to make some new doors at the Hull Dock Offices I believe! My constructional abilities (practical skills) have always exceeded my technical knowledge, and as a consequence, right back to the days when I wore short trousers, I've built countless projects that look quite presentable but have often not worked - sometimes down to my having made an error, or other times, because I've faithfully reproduced errors or shortcomings in the design that weren't apparent to me.
In my teens, (when PW was known affectionately as 'Camm's Comic'), as my gullibility threshold increased, it dawned on me that terms such as 'An Enthusiast's Power Supply' or 'An Experimenter's Short-Wave Three Valver' meant 'you need to be enthusiastic to build this and expect it to work' or 'we experimented with this design to try to make it work but couldn't - maybe if you experiment a bit more, you might get it to work'? As my technical knowledge has increased over the years, the pace of change has accelerated apace, leaving me further down the field - PICs, SMDs etc. But I'm happy in my own skin, bobbing along and enjoying myself along the lines of my sig block!
