Hi!

Anybody who's needing circuit and layout diagrams for the Philips PM3305 35 MHz Four Channel Digital Storage Oscilloscope can obtain these from k04BB – I uploaded this!

However, for some mysterious reason the layout diagram of the A2 DC Switch–Mode Power Supply unit got omitted from the k04BB manual, if you download the PM3215(U) Service Manual free from the Internet Archive (white and brown cover), you will find a good clear non–furry layout of this power unit which you can print out and add to the PM3305 Manual – the PCBs are virtually identical!
