This made my day and really brings back memories! Well done and thank you!
I can remember building (from this type of Philips kit) (60 years ago) a simple Long Wave radio. Back then in the UK Radio 2 (the Light programme) was transmitted on 200KHz 1500m. I built this simple radio into a small homemade wooden box and used it regularly for a few years. I think the RF transistor was an AF116 the front end was just a tuned circuit. The simple audio amp was I think two AC126 feeding a small loudspeaker.
On the front of the wooden box there were two of the (thinking back now – iconic) Philips kit red plastic pointer knobs, one for volume and one to tweak the tuning if ever needed.
