It's great you had a go fixing this old tape machine - Tape Apes will chatter but you are a 'class man' for doing a good job on these difficult machines. Well done sir... 🤓

Just something to note in case you haven't discovered it yet. Someone has modified the headblock on your machine which essentially converts it to an RS-1500. It looks as if someone replaced the heads on this and converted it to 2 track record/play Your 1506 originally came with a RP-2422 (4 track play and record, 2 track play) Since the heads were swapped, it is now essentially the same as an RP-2224 (2 track play and record, 4 track play), even though the labels on the front of the headblock were not changed. I have both an RS-1506 and an RS-1500 and confirmed on my machines.

Your job is excellent. You opened the machine, you must be completed the cleaning process of motor winding from the inside will gain additional speed in the tightening of the tape I have 1700 of the effects of dust the right pulley was weak after cleaning, she is back to work efficiently. best regards from saudia arabia. tm

Thanks a lot for this video , this helps me a lot.

Very cool John! Very thorough. Keep em coming.

Hi BigNasty, Thanx for the video! Thought the accordion shaped rubber things were called "bellows" not baffles? Good video on changing the brake pads.

I need to get me a pair of those technics reels. They look nice.

I have always admired these tape recorders since I first saw them in an exhibition in the 1980s. However, since I became familiar with the design of the brakes, I have been rather disappointed. Why did Technics use such tiny brake shoes? This means that early wear is inevitable. Akai and Revox used band brakes with about ten times the friction surface and practically no wear.

hi have a RS1700 there only one thing bad the right reel table had a bad bang the reel hold is now bad i had to take the reel table apart a re tap a M4 BOLT there a brass in where the reel hold part is now it still works ace now

hi you talking about a tape deck having a fall i had a teac 3340 drop down and bent a reel motor i had to swap over the main motor cor save cutting any wires a tape dropped on my rs 1700 14 inch tape right side of came the right reel holder i am a tec so i can fix it easy i have a scully 280-14 4 track 3 speed deck pimped up with tascam 30 line parts

I would love to have a Tascam. I’m not a tech but besides this Technics, those are my dream decks.

Great video just what I need to see how to change brake pads and ajuste it on my Technics 1700 I think that is the same I hope and thanks for the video , where did you buy brake pads ? 👍

I have the Teac A-1250S. Like yours I only get the recoil on the fast forward. So which side should I replace the pad on? Thank you, and great video !

You need to replace the pad on the reel that’s “coasting”. So, if you winding right to left, the left reel is pulling while the right is coasting, the right reel would be the one you’d need to replace because it should be braking to prevent over turning when the left reel stops pulling.

@@SDsailor7 If it stops when you stop it or plays normally, I wouldn’t think it was the brake pads. Not being an actual tech but I would suspect a switch because if it continues to run after all tape has been through, it could be a tension switch. Something is failing to tell the motor to stop. If the motor stops but the reel continues to free wheel, I’d suspect the brake switch. But, like I said, I’m not a tech and they are hard to find now a days.

@@1SpudNuts1BigNasty-DIY I found out that when the pitch control knob/switch is in the off position the tension arms move up and down constantly and it distorts the sound/music but if i have the pitch control knob in the on position no more problems, the tension arms are stable and the music plays fine. Is the pitch control supposed to be off or on in normal operation? The owners manual does not say anything about it.

That's the tape! Not your Brakes! When the deck operates, the brakes are completely disengaged and it uses the supply side motor to provide reverse tension. The tape has SSS (Sticky Shed Syndrome). The tape is shedding enough sticky material to bind up the transport. Keep using that same reel, and you'll gunk up your tape path possibly put enough stress on the motors to fry them. Get the service manual. The location of the squeal is irrelevant. The tape itself will squeal and can sound like it's coming from anywhere along the tape path. And it can also cause the tape top ride over the guides. DON'T ADJUST YOU GUIDES!!!

Great video, glad to see you want to save those old machines, they were classics made with quality. But there is nothing wrong with the brake, the tape is shedding and sticky. You have to heat the tape in the oven.

DO NOT simply "heat" in an oven !!! You'll screw it up !! Use a food dehydrator. RESEARCH !!! It's called SSS for sticky shed syndrome. If not corrected, you'll burn out your VERY EXPENSIVE MOTORS !!!
