Back in the early 'noughties' Raymond Haigh produced many interesting and nicely designed projects, both from a constructional and aesthetic angle. Various receivers and amplifiers. (It was he who designed the Radio Bygones Wobbulator, later re-published in the BVWS Bulletin). He wrote a 4-part constructional series in EPE back in 1982 on simple amplifiers, and on speakers and crossover networks etc. The four parts can be found at these link:

I'm very much in John's mould - right back to being a schoolboy in the mid 1950s, my constructional ability has always exceeded my technical knowledge and I've always built things neatly, or at least, to the best of my ability. Sometimes they worked fine - too often they didn't! I know that many people say 'I just chuck things together and if they don't work, I haven't wasted much time on them'. That just isn't my style, but as a consequence, over the last five decades, I've built countless projects in which I've carefully and unwittingly replicated the errors. Having nicely boxed projects up, which will never work, I've then not had the heart to pull them apart and rob them for bits. At one time, I had quite a showcase of elegant, (but entirely ornamental!) non-functioning projects.

As I moved into my teens, I came to realise that article in Practical Wireless such as 'an enthusiast's TRF' meant you had to be an enthusiast to redesign it so that it would work. An 'experimenter's power supply' didn't mean 'a power supply to help you with your electronics experiments', but power supply design for you to experiment with to try to get it working. I did have my successes though - back in the mid 70s I built the PW 'Tele-Tennis' project for our two sons and our house became a magnet for other kids to come and play. My younger son (now 45) still has it and it still works!
