I just found one of these last weekend during our small towns "curb days" weekend where people can throw whatever away on the curb for the city to take to the dump. I gave it to my buddy who plays with/works on electronics to play with and after giving it a go over he said all it needs is a new needle, everything works perfectly. Very informative video ~!! LOVED IT!!! I do not normally have the attention span for anything over 10 minutes even if the content interests me , mostly because of the way the person presents the video and format and information. I was BEYOND surprised and even went to get my girlfriend and we both sat with smiles on our faces, drinking our coffee, learning about our new turntable!!! She's from Germany and brought over some records with her 20 years ago and hasn't opened that box since then because she hasn't had a turntable, this video brought out some excitement for our new toy!! We just have to order a new stylus and we're ready to rock!! Thank you for this video !! You're doing a great job! I'm actually going to go watch some of your other videos! Cheers!
The drawer slide motor on my "family heirloom" PS-FL77 was having ever more trouble sliding the drawer out, until today the drawer got stuck halfway. Your video was of great value to me, knowing now how to open it up and get to the relevant parts. Turns out the motor mostly had some trouble getting started, and keeping going. Probably cleaning and applying new grease as you show in the video would have been good, but for now, just letting that motor make quite some rotations both ways (more than it has "travelled" in years) seems to help a great deal. I couldn't have done it without this video, so a big thank you!
This thing was brand new. The platter of a record player always comes separately in the box and the cartridge often too, protected 12:20 that's not lithium grease for sure, because lithium grease can destroy plastic over time. If you use lithium grease, i would remove it. It can negatively impact certain types of plastic.
I'm sorry that I didn't respond to your comment from 2 YEARS AGO. My fault. I've heard that lithium grease thing from a few other people so I'll be following that advice, thank you. Luckily I have a 3D printer and have used it with great luck to model and print replacement gears for many various types of equipment. So if anything does break, hopefully I can use that. As far as the turntable, its still working perfectly to this day. It blows my mind that I can have it turned up so loud that the windows are rattling yet it never skips or has any low freq reverb. Also new albums that people complain about IGD after a couple plays, this doesn't seem to have an issue or cause an issue. Just is amazing how good these tonearms are. I've always liked Technics turntables through the years but this thing has won me over, I absolutely love it. I'll be keeping an eye out for some old higher end Sony Linear Biotracers in the future.
Would love to get your breakdown of how to lubricate/align the drawer slides on this TT as well as thoughts on cartridges and pre-amps. I just picked up this unit off the'bay (after a long time coveting) because it fits in my rack system. But, the RCA cords were cut so I had to resolder new cords and my drawer doesn't seem to want to slide in very well. I will follow your re-lube vid to a T when I get a new cartridge in, but the good news, it works...I've heard mention of others shimming the drawer slides a bit to better realign...and was wondering if parts from the often cheaper Realistic LAB 1600 might work on this unit. Look forward to your thoughts on how to keep this great biotracer working.
Yes, just like the previous guy said.... You didn't place the rubber platter mat on correctly. You need to match the slotted holes in the mat with the slotted holes in the platter.
Thanks for a great video. I have one of these and I'm only getting audio from the right channel - even after installing a new cartridge. (And I know from swapping inputs that it's not a problem with my amplifier.) Do you know how easy it is (or not) to check all the audio connections from the cartridge connector through to the audio output? The service manual makes it look like I'd have to pretty much disassemble the entire tonearm assembly to do that - but is there some easier approach that I'm not thinking of?
My old one I took apart YEARSSSS ago so I don't remember too much. But really its just a matter of taking the case apart and testing the wires with an ohmmeter. I believe the wires in the tonearm go to a PCB and from there its sent out to the audio jacks. Probably broke loose around that PCB. Again its been so long I don't remember but yeah you'd have to tear the unit down.
If you check 13:27 you'll see a pcb in the upper right hand corner after taking the bottom off. The thin wires going up under that gear I believe are from the tonearm. Sorry I don't have a pinout, but you should be able to run an ohmmeter from there to the connector on the arm where the cartridge plugs in. If one of those wires is cut then you'll have to either re-solder it or replace it completely. Also check the solder joints and wires going from that board to the leads exiting the back.
Sorry for not responding for A YEAR. Completely my fault. I replaced the stylus, checked and adjusted the tracking force by the pot under the platter. This can be measured using a digital stylus force scale, picked a new one up on amazon super cheap. Believe its the same model that techmoan uses. As far as speed, after playing a few albums the speed issue went away, so if it ain't broke I'm not fixing it.
my fl77 hAS A BAD SKIPPING PROBLEM THINK THE ARM IS NOT ADVANCING PROPERLY MAYBE ITS A LUBE PROBLEM OR IT NEEDS A NEW ARM DRIVE BELT WHICH YOU DID NOT MENTION ALSO IS THERE A WAY TO INSPECT THE STYLUS WITH OUT REMOVING IT
probably needs a clean and relube. This one I haven't had to touch (knock on wood), except for a new cart and stylus. as far as checking the stylus without removing, its difficult to see. Easier to just remove it, if its a standard pmount, the stylus just snaps out of the cart.
hi. After 35 years or so mine just turned off in the middle of playing a record and will no longer power on. I have replaced the 2 large capacitors but that did not solve the issue. Have you had this issue? If not is there something you would suspect or something I can test? thank you so much.
That sux man. Um. No. It's been a while since I had this apart so I dont even remember anything about the power supply. I'll take apart my parts unit if I can find it and let you know
The earlier but similar PS-FL3 had quite a few fusible resistors which seem to become more prone to blowing as they age. I replaced mine with normal resistors in series with suitably rated Polyfuses, which have the advantage of self resetting if you leave them a few minutes after they trip.

Sorry I just saw this comment. BTW I love your user name lol!
@@Electronicle LOL, 3 years! Totally forgot about this comment and video!

I'm glad that you got that working and hope its still working for you A YEAR LATER (yeah sorry about that).

Also, I'm shocked that Sony didn't make this unit Quartz speed controlled like most other high end direct drive turntables.
Fantastic video keep them coming.

Thanks for noticing but yes I'm aware of this. I guess I didn't bother when I shot this because I was simply throwing a 12" on it anyways.

@@Electronicle Thanks for getting back to me - that's pretty much as I expected, and useful to know that I wasn't overlooking some simpler method.
I have a question about the clip on the audio connections. Where is that to connect?
clip? You mean the ground wire?
Did you ever video the speed and other adjustments you needed to?

@@Electronicle thanks for the video. mine stop moving the arm. What do you advise to do ? Thanks
Please check t901 transformer. There is service manual available with full schematics.
