Differences between a Porta 02 vs. a Porta 03?

[e.r.stevens]

Hello,

I just threw in a half-serious offer on eBay for a Tascam Porta 03 and won it. It won't be coming with a manual or charger which prompted me to do some research on it that didn't amount to much info. There isn't a manual online for it and other users have mentioned to just look at the manual for the Porta 02 as reference.

This led me to think what are the differences between the Porta 02 and 03 anyways, concerning:
AC Adapter
Phones (mono square button on the 02 and not the 03)
durability/longevity
Dolby

and anything else somebody might have some insight on differentiating the two for me.

Thanks, analog allies

P-02 expanded version of the P-01.P-03 entry level-sold for 99.00 no EQ,track spacing incompatible with any other Tascam 4 track cassette recorder.P-02 hands down better.

The Porta 3 is super bare bones. 2 inputs w/ just mic trim and pan, stereo out and runs at regular tape speed. Pretty good 4-track for certain things though. I believe that every machine has a purpose even if that purpose is to a make a complete mess.
