As a 70s deck, m33 seems kind of weird compared to my newer decks.

This deck has lots of potentiometers inside for calibration: output level and bias, input level and bias, fluorescent meter 0dB and -20dB level, etc. And I really have to carefully adjust all of them (plus head alignment and playback speed) until it sounds and looks right. None of my other decks are like that. Maybe this is normal for 70s deck? I don't know. I'm glad it's working properly now.

Another thing that seems quirky for me is that, when I push the stop button, the motor actually stops. For my other decks, it would just shift the gears, but the motor would still be running. That is probably why the m33 sounds a bit unstable for the first second or two. This is not entirely a bad thing though, since the belt would probably last longer this way.

Another uncommon thing is that, the transformer is sitting above the board, directly above the line input&output no less. My guess is: 1. they want to isolate the transformer; 2. they want to use a single board; 3. they want to make the transformer as far away from the amplifying components as possible. And final design happens to leave the transformer there.

The whole case is made of metal. The front panel is a thick piece of aluminum. So it seems kind of bizarre to me that they would decide to use empty plastic for the buttons. I would be a lot happier if it's at least solid.

Well, complaints aside, it's actually a decent deck. It's sturdy and good-looking. It seems promising that m33 will work for a looong time.

Amazing deck!
Built like a tank, very reliable, never changed a belt in mine.

Sounds really good, with support for 3 types of cassettes, independent input / output levels.

Looks great, with a lit tape window and a large fluorescent peakmeter. Brushed metal finishing and all-metallic knobs and piano-keys.

Only minor complaints:
Plastic casing (top and sides).
Also letterings/logo on the face tend to get erased when wiping with regular cleaning fluid, so be careful when you clean the front. Mine letterings faded unfortunately..

Overally its an amazing piece of a classic deck.

A very high quality deck. The feel of the controls tells you everything. There is an amber backlight behind the cassette. The cartridge lifts up, automatically, about 1/2, when you eject. The LED dimmer is a nice touch. There is a 2-stage stop that gives a slight tick before the tape shuts down at the end of the side. This is also good, because the deck does not startle the listener.
I almost bought an M205, but I'm glad I opted for this more expensive Technics deck. The sound is excellent.
