PHILIPS EL3300 ear piece

[Ekcoman]

Just finished sorting a EL3300 and noticed that unlike the one a month earlier this model had a socket for an earpiece unlike the one a month earlier. Don't think the EL3301 or EL3302 had one or did they?

That's a week earlier, not a month. Is the full model number EL3300/15 in both cases or are there any additional letters?

On my EL3302 I used the audio output on the 5 pin 240° socket. As this was also used for the external power supply, I made an adaptor with both a 5 pin socket for the power supply and a 3.5mm jack for an earpiece. A small metal can that had contained a bulk 35mm film refill, provided a conveniently-sized screened box.

Nope both are EL3300/15. Never seen before and not a later home adaption but obviously built into the white molding so been designed that way for production at the factory.

Very interesting as you probably found the exact week when this design was changed... What are the chances?

Also, it must have been regarded a "minor" design change, not even justifying upping the revision code from AH02 let alone the model number. Quite strange, actually.

Strange to see non-DIN sockets on any Philips gear of that era, in fact.

I seem to remember that my grandmother had a yellow Philips transistor radio with a 3.5mm earphone socket on the side which would have been made in the early 60s. It looked like the blue one at

although none of those pictures show the earphone socket.

It couldn't be a well done post sale modification then? The picture of the hole around the 3.5 mm socket looks a bit uneven in the picture but of course I don't have the machine in front of me. I would have thought that repair shops at the time might have attempted this type of modification and gotten quite good at it over time.

(For instance, I remember my father had a battery operated tape recorder which he had modified by a shop so he could use a non original external power supply with it).

I tend to agree that it’s a well executed, post-manufacture modification.
