Thank you so much, you are a life saver !! I just bought my Porta Studio and it is doing this exact same thing. I now know how to fix it. The fact that you are not talking and getting right to it, is so much appreciated.. You are the MAN!!!

My Porta 03 has the same problem. Do you think it's ok to use a 2SB649A transistor to replace the original? I couldn't find a B891. Thank you so much for your videos! Here it is 7 years later and many people are still finding them so helpful.

I always find your information useful. Thank you. I have a PortaOne and I can hear the input sound and record to tape, but when I play it back the tape works but the vu meter doesn't move and no sound comes out. Can you give me some advice?

Excellent video. I'm curious why WD40 was used instead of a silicon grease or lithium grease. Cheers.

Thank you ! I can’t believe how quickly you made this video. I’m glad to see it’s a very simple power structure. I’ll be opening it up later this week.

Hoping to find a video on “won’t power on”

Because of this video I just repaired my tascamPORTA02MKII, thank you!

Thank you so much for this great video! I I had never replaced caps on a PCB, but this video helped so much. My Porta 02 is now working great.

Amazing!!!!! I'll need to buy some cassettes now!

I already ordered a belt, but out of curiosity: I use my 280 quite often actually. I was trying to make a short term substitute belt using a skinny rubber band while I wait for the proper replacement. Tension was a little high, but it fit. Only issue was that it kept falling off the flywheel after a few rotations. Is that to be expected for a belt that’s not the right size? Or is this issue likely to carry over to the proper belt, meaning I must fix something that might be wrong with the assembly?

Thank you very much for sharing your knowledge! incredible! One question, after carrying out the repair as you did in the video, is it necessary to calibrate the equipment?

Question about the first Tascam in the video, I found one for like 20$ but the record and play button will not press down. What causes this? Any info is appreciated.

I have the Japanese version of the 464. It has no XLR, but has BBE sonic maximiser.

Hello 3rd Island, thank you so much for sharing all this knowledge, it saved me so much time already! I was wondering if you knew anything about a X-28 not rewinding? All other functions works, when i press Rewind, it starts 1sec and then literally switches off, screens test all position. Like a false contact? I took it all apart, plugged it, the tape rewind fine when the module in my hands, other boards like the mixing board taken off.

I have a MT2x that I would like to get functioning again. I imagine that you take in repairs? If so, could you send me to your website?

Very useful video Thanks a lot!

Thanks my friend for sharing the video and useful information. Greetings from Egypt

I just had the same issue with my Fostex 380S. I burnished the switch contacts with some notebook paper, and it took the corrosion off of the switch contacts. This was a thing we did with old rotary telephone stepper switches way back in the 80's and 90's. We used paper if we did not have a hand burnishing tool. Using very fine grain sand paper will work okay since these are low voltage low current switch contacts. Your video helped me diagnose why my unit would power on and just have all of the display elements lit up indicating an error condition. So, this can also be applied to the 380S model. Now I have to find out why the heads and Capstan are not functioning.

Good idea ❤

Great video ! Thanks

Great video really helped. So I got the Porta two working. Everything seams Ok. Only problem is the pause button. It works fine but does not stay engaged. If you let go it starts again. Any ideas how to fix this would be appreciated. Thanks .

What cassette is playing?

Thanks for your video! I want to add, i am useless with tweezers. I substituted a mini spring hook that i purchased for such jobs as this.

Thanks for the video, another Tascam saved :-)

Hey man, I’ve been going down a rabbit hole with all of your repairs! Would there be any way to commission a PS M1 supply for a Tascam 644 from you?

Nice I have a 4070G I'm about to start working on right now and this is helpful to see before digging in.

I need the Base Head replaced on my Porta One Mini Studio. Can you repair?

Reckon I could make a 240v one for my 424 mkiii in Australia?

Hi ! What type of grease do you use to lubricate the sliders? Thanks you

Thanks to this Video, today I repaired my two TASCAM PORTA TWO ! Thank you so much. 💝

Hey! My MT2X is having a problem that i don’t quite understand. There is a tape stuck in the machine and the motor is stuck running in play. I believe i saw on another video someone say that the buttons to control the tape mechanism are mechanical not solenoid driven. I have not opened the face of it up as i am not an electronic guy. Is this something i could possibly address or would i be better off taking it to a professional

nice to see you again 3rd island fixing 4 tracks ! i have a few mt120 that all have mixer problems, poor gain on various tracks. these mt120 all seem to have similar problems

Another good repair! Thank you for uploading

🫡🌹

Better than original

Just fixed a second hand porta one that had a similar problem - the pinch roller was not fully engaged against the capstan and I realised the spring broke the plastic part you have shown, thank you immensely

Bro how the fuck did you just pop it open 😭

thank you!!! this worked so well, i was so worried that i wasted $250!!

Great video thanks for posting ❤

thank you!

Hi, thank you very much, your videos are great. For me the spring is completely broken and impossible to find the name of this type of part... Do you know where I can buy this part please? THANKS !

This worked. Thank you!

@3rdisland477 Are you available for repair still? My husband has one of the Porta05 in pristine condition, original box etc but there is a tape stuck and he believes the play button was stuck in the engaged position. I don’t want to risk damaging it further by trying to fix it. Thank you!!

I have sound from headphone port with instruments played live, but no playback of tape. I know it records properly though after trying recorded tape in another tape deck. What do you think the problem could be? Thank you!

Hello 3rd Island! Watching your video, I opened my fostex X28H to replace the belts. Before closing it again everything worked correctly; but after closing it with the rear screws, the device does not turn on. I have measured the adapter and it works fine; Even the input jack works fine, but I don't know anything about electronics and I wouldn't know what to check now. Any suggestion will be very welcome. Thank you so much!! Dan

Man, I'd love to get mine modified. It barely works, and im recording an album on it

This machine is available for sell on ebay www.ebay.com/itm/266637089070?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=1rMAmpwuRtq&sssrc=4429486&ssuid=1rMAmpwuRtq&var=&widget_ver=artemis&media=COPY

Thank you for your video! Very interesting as always. Clever modifications.

I tried replacing the capacitors with 220µF 25v (originals were 220µF 9V). This produced some sound, but I can only hear the tape i play in it very faintly with the volume control turned all the way up. What do I do now?
