I just get a 10k pot and find the motor leads, hook on there, boom. Working on the motor directly of anything to control speed is always best for me, but your switch bypass works too.

@seanchud 5 лет назад

I've been looking for this exact type of tutorial for what seems like forever. Thank yOu!

@Barry7777777 5 лет назад

You can get back up to normal speed without using a switch - just use a very high resistance control like 1 to 5 megohm. The control you're using is too low a value, causing a resistance (or in this case, a conductance) to remain even with the control at its highest resistance setting. 5 megohms should be more than enough to present a virtual open circuit at the highest setting - but beware: That much range squeezed into 330 degrees of rotation will make the control extremely touchy, meaning a tiny movement will have a huge effect.

Hi! So, as I appreciate the making of this video and the people commenting on their experience, for it is very helpful, I figured out I might as well share mine! Luckily I went the safe way and bought a 10K pot, I thought "well, if it doesn't do the trick I'll add the switch, no biggie", however idk! It just worked! Normal stuff, connect ground, and in and out. If I leave it to let's say around 4.5K (idk if that makes sense but I mean imagining there are 10 speeds on the knob) it's the standard speed. If I turn left It goes slower, and if I turn right it goes faster. It worked without the switch and with a 10K pot for me, so I'm guessing it just has to do with the voltage that the machine uses! You can use a multitester to check the voltage on the circuit and calculate (using the ohms law) what pot will work best for you. Cheers guys.

Hey man, I don't know how I've never found your youtube channel before now. I love your instagram stuff, and this is something I'm hoping to do with at least one of the old broken walkmans I've bought from ebay. Many thanks from sunny England, and keep up the great work, it's really inspiring.

Great video, actually informative instead of just "do this then this" etc.

@shawnlennon1947 Год назад

hey warning on the input idea. im pretty sure those mics require 5v and anything you input will have the 5v going into your gear. I dont know if its bad but its something to consider. also im a noob and I was told this by another guy so take it with a grain of salt. I would just test the wires with a multimeter to see if there's any voltage coming out of it.

@Betkho 5 лет назад

@edmundmoon556 3 года назад

You could find a push-pull combined pot. So can forego the switch.

@manueltietz3761 2 года назад

Well I've tried a few spots and a few worked but than it seems like I've connected the wrong ones and it just stopped working and the motor wont turn anymore. Seems like I broken this thing for good...

@0xptomaine 3 года назад

came here after Andrew Huang video good job man

@THEWEIRDNET 5 лет назад

Increasing the range of your variable resistor should help get closer to the original speed. Thanks for sharing, very useful video!

@stevieschmidt3719 5 лет назад

I did 100k and got about a half step off. You then sacrifice the top 1/2 or so of your knob on going a few semitones, and theres less space down low for the juicy spots. I decided it was worth it though. You could theoretically add a fine tune by putting a smaller pot in the chain too. (I think)

@stevieschmidt3719 5 лет назад

was wrong about the fine tune

@niklasvfx 5 лет назад

@Nilbog-Hunter Год назад

When doing this on a older cassette, the only thing I can find is it going up in speed, I can't find anything that slows it down. I cant find a trim pot either. Not sure what to do

@GeminiHorror Год назад

You mean like find a trim pot to do the mod? I got mine on Amazon if that helps? There are some players that will slow it down natively like the marantz cassette decks and the tascam 4 tracks but they are getting pretty pricey. Alternatively you could get something like the chase bliss blooper but again that’s not that cheap. There’s a cheaper donner looper on amazon(i think like under $100 US) that can slow down a loop. Hopefully one of these things will help!

hi done this to a tascam 238 that the servo was dead i pimped it to belt drive it now 1 7/8 to 7 1.2 ips play back only now do i record i have a high speed record in real time i did a video over 10 years ago

@alexvaught106 5 лет назад

Really simple question, can you give me the make/model no of that second tape player you showed off with the 40 percent speed knob? I want to try to find a couple on ebay.

@0228christian 5 лет назад

Looks like a Marantz Pmd-201, or perhaps a 221 or 222. Whatever it is... they're crazy expensive right now. I managed to find a Pmd-101 in perfect condition for $40, which was a great deal, and it has the pitch knob and multiple speed modes, but it's mono and doesn't have the other features of the 200 series.

@samplikprost 5 лет назад

Please tell me, this trick works only with players who have speed adjustment? Or is it possible on regular players ? Without speed adjustment

@kbg- 5 лет назад

Am I correct in thinking this shorts the motors V+ to ground via potentiometer to drain some voltage and speed alongside it? I appreciate the tutorial, I'm just trying to understand why this works. Cheers.

I have the same player the trimpot that is the speed controller is actually right next to the point that slows it all down so i think its related to that somehow

Hello! First of all thank you for this really good tutorial :) I am wondering if it needs to be the General Electrics model tape deck, or if I can quite simply apply these steps to another variable speed model? Thank you greetings

@GeminiHorror 4 года назад

Yes it should work on anything but it will take some experimenting to make your specific model work

@grungrun3377 3 года назад

after some experiments with my own tape player and a long conversation with my technic interrested father, i finally get my on my own DIY Cassete speed mod. By the way my cassete player needed 10 Ohm instead of 10k Ohm. ;)

Hi!!! Nice !! I stay investigate about control tape for me, I’m maker and I love made sound machine, so, I want made machine like to om-1 (ondes magnetique) (why buy if I can do it and I also dont want to sell it).... so.... my question about it.... in the om-1 control tape cassette with cv and gate (sq-1).... How? .... cv is easy ( I think) like the “analog industries” video... but and gate? ... mixed with push button and pots.... do you know how om-1 works? Sorry for my english and thanks for your time!!!!

Yea it's pretty easy, you just follow the mic to the board and if i remember right it even says "mic" on the board then solder in your input, i did this with a 1/4" input a while ago, see this example instagram.com/p/BrkW_oyFHqZ/?igshid=c7y9dybj3ml4
