Hi Nando,
I just found a couple good posts from Sam over on TH... It sounds like a couple power supply parts, a relay, or the microswitches in the tension arm you have noted. Sam's deck experienced the exact set of issus as mine in that it played a tape or two and then just stopped.....
I need to go home a rip things apart once again!
We'll get it....... just a bumpy ride getting there.
Thanks for the words of encouragement.

Hi Guys,
I really think the ability to fix things is a curse at times!!
It looks to be one of the micro switches that is bad. It has a couple hundred ohms with zero current, at a couple amps nothing will ever get through. Now to find a replacement. I'll take a photo as the whole front of the deck is apart. One thing about everything Pioneer I have worked on thus far has been engineered pretty well from an assembly point of view. Sure can't say that about some of the others.
Thanks to Sam's post on TH, it really made finding this one much less painful. Note: there are a couple pins to short so one can actually bypass the micro switches to test before ripping everything apart.
Yes, I feel the vibes Nando!!!

It's good to hear you seem to be narrowing down the problem, Robert. It sure saves a lot of time, when someone else has had the same problem, and you can start there.
If you are interested, I have a 7'' reel I recorded on my Pioneer RT-707 not long ago, as sort of a test tape. It has easy listening tunes on it, with plenty of range in dynamics. I could send it to you, and if there's anyone else who would like to hear it, they can share it. All that I ask is to have it retuned within 6 months, or so.
PM your address to me and I can send it out this week, if you wish.

Hi Guys,
Received the microswitches yesterday and installed them last night, perfect fit. Everything is now back together and working for the most part. I was able to play tapes in either direction and the sound quality is top notch. One small gotcha is the FF mode does not appear to have maximum torque with a full reel so something needs to be investigated there. Off to find that schematic, spring scale and SM one more time......
Hopefully I can try Nando's tape shortly. I want to make sure everything is working as expected so I don't trash his masterpiece!

Hi Robert,
It's nice to hear how fast you are progressing with your RT-909. I'm confident there won't be any damage to the tape, no matter how bad the deck could possibly malfunction. If this had been a 40 year old acetate tape, maybe, but not the Quantegy tape. I should have bought more of this tape, back then, as it's a solid performer.

Hi Nando,
Looking forward to trying your tape as I don't have any Quantegy that I know of. Is it similar to Maxell in performance?
I have a couple boxes of acetate tape that I am not sure what I should do with. Some of it still looks Ok but I have not actually given it a spin.
I was playing Maxell tapes last night on the 909 and was very impressed with the quality. I like the Pioneer decks more each time I mess with them. Belts arrived yesterday for the RT-1020H so think that will be the next reel machine that gets looked at.

Robert,
The Quantegy 480 tape is from a carton of 20 1/4" x1200' x 7" reels I bought, perhaps six years ago, when Quantegy was still manufacturing open-reel tape. So, unlike Maxell tape, which hasn't been manufactured in some time, this is a good match for all three of my Pioneer decks, RT-707, RT-909, and RT-1020L. I do have Maxell 35-180, and TDK Audua, but I prefer to use the Quantegy.
