Happy to report that after changing those two transistors, it seems to be working fine. I got both of them off of eBay. Not sure which or if both transistors were bad, but just replaced both. I appreciate the help along the way very much! Hopefully this journey will also help others.

Thank you!

I figure it will take a week or better to get so I'll just get both. So.... I found a 2SD317 but not -P - same with the other one the 2SC733-Y - found it but without the Y? Sorry for all the questions (: Learning a lot.

As I look more closely, the schematic shows Q1 as 2SD317 and Q2 as 2SC733(Y) The parts list for the voltage regulator shows - Q1 as 2SC733(Y) and Q2 as 2SD317-P. (Reversed) The actual part put in at the Q2 location as shown on the voltage board is the 2SD317-P by physical inspection. So, I...

After putting it back after my inspection, I went to verify my voltages. I found two places that I thought were zero, but did or do now have voltage. This was probably caused by my timidness in touching the probe - or maybe a loose joint I can't see. In any event, here is a new diagram showing...

In looking at this a little more... And I couldn't see this at certain angles. It appears that Q2 - I can see that he's been moved. It seems that he was bent over and attached to the board? Anyway, he's clearly come loose. Not the leads that I can tell, but the unit itself. See my pictures...

Thank you two for your help! I don't see anything obvious - I've attached some close up pictures. The measurement between the two green marks - with no power on - ohm reading is 1K. like 1.0038 - something like that (on the 2k scale). Even though I got a measurement above, I still did the...

Ok - thank you for that info! Here are the voltages I found. It's possible I made a mistake - happy to recheck something.

I tried measuring the voltages on the Voltage Regulator board. I've not really done that before so was pretty timid about it. Nothing sparked. In the diagram below, I think I mistakenly thought the GRN was the ground. Now, I'm not so sure - I think that means 'Green' wire.... I'm bummed now...

Yes, transport seems fine - thanks for confirming things we can move past. I'm not sure how to exactly do what you ask. In the image I've attached in this message - the voltage regulator board - next to the AC Input - I should attach negative of my meter to the case and then the positive to...

Here are some images of the entire area showing flywheel and pinch roller assembly and switches; the Right Tension Arm Switches (S2 & S3) ; and close up of the board above the 'AC IN'

Hey - thanks so much for your response. This started with me trying to get a machine going for my brother in law so he can digitize a bunch of tapes he has (: On the pinch roller issue - basically it would not automatically go up to the capstan unless you pushed it up. Trying to move it felt...

I have a Teac A-2300S (very similar to 3300). I fixed the common pinch roller problem (which I've done on other Teac's twice before) and after reassembly there isn't any sound. Transport works fine though (: The switch 'is' on Tape (not monitor), and there is no VU meter activity (except the...

I got this working. The two switches for the right tension arm - that assembly - I must not have put it back exactly right. I had loosened it to get the pinch roller assembly out to clean it. Took that switch assembly apart and tried the switch and the motor fired up. Reinstalled that and all...

I have a Teac A-2300S and the Capstan Motor, and the FF & Rev motors won't work. I picked this up and the pinch roller wouldn't engage due to grease buildup. Took it apart and cleaned them (as I've done successfully on one other Teac) and now that part works great. Hold up the right tension...
