I just purchased a teaberry stalker IX with tr32 missing, trying to figure out what is supposed to be there so I can replace it, the audio is horrible with that hack mod done, I personally just like to tune them and call it a day without cutting mod limiters, gotta remember they’re supposed to be in there for a reason

(y)

The 2SC945 was a fairly common NPN transistor, I believe the "A" signifies that it's suitable for Audio Frequency amplification (& low speed switching);
"Q" denotes classification of hFE, Q would be an hFE range of 135-270.

To avoid weeding through the mountain of fake parts commonly found on amazon/ebay,
I recommend purchasing this component from a reputable retailer.
Some retailers have a minimum purchase requirement (though Mouser doesn't)!

You could try finding a modern component that would be functionally equivalent,
this would be easier than locating the (new old stock) OEM part.

The Fairchild/ON Semi KSC945YTA looks to be suitable at a glance!
