I recently went through a similar exercise with my Q*Bert arcade machine. I was checking voltages from the transformer, at the power supply, etc. The whole time I'm thinking a bridge rectifier failed. Nope, just a fuse. Another reason to always check the fuse with a multimeter instead of just a visual check.

What an easy fix! Getting a bargain 808 for a simple bad fuse would be awesome.

I learnt 2 good lessons from your video; 1) Don't measure the PSU with a potentially faulty load attached. 2) Simple parts (fuse, in this case) can fail in complex ways. So thank you for that.

The problem doesn't have to be complicated always...finding it without taking everything apart is the trick! Well done! Love your videos...

I like your thought process and trouble shooting. To see that a fuse that wasn't blown cause the issue was quite surprising.

@synthchaser I just retrieved a TR-808 from storage that is configured for 220V and I want to do this EXACT conversion to 110V! What perfect timing that I found your video

Awesome. Sometimes the problems can be so simple. I've been tracking why my Linndrum doesn't play the kick for over a year now and still can't find the error.

New Synthchaser video day!! 🎉. Question, you were about to check the fuse to measure resistance before it broke. What resistance value would be in range for the working fuse? Or was it just a continuity check? Thank you!

It's nearly always something in the power supply. Change to different primary voltage use generic 9V and 12-0-12 ones, doesn't have to be exactly same, line voltage varies by up to 20 percent and the heatsinks just burn off the excess.

I kinda need to do the opposite: convert a 120V American Ensoniq ESQm to 230V European voltage. But the ESQm has a complicated transformer because of the VFD, not to mention that the service manual isn't very clear about the power PCB.

So uhm, can I buy that 220 transformer from you? I’m in The Netherlands and have a 110 808.

You could've removed the fuse with any basic Vanderweiss tool.

@@newking70 the owners existing line voltage is 110v, the unit required 220v line voltage, so the owner used a step-up transformer to change line voltage from 110v to 220v. Now replacing the units existing internal transformer to one that has an input AC voltage of 110v eliminates the need to use an external step-up transformer.
@RWL2012 4 ай бұрын
a step *_down_* transformer would be used for powering a 100-120v appliance in a 220-240v country, whereas in this case, a step *_up_* transformer was being used to power a 220-240v appliance in a 120v country. he then simply replaced the 808's internal 220-240v-input transformer with a 120v-input transformer, effectively changing the 808 from a European one to an American one and eliminating the need to use an extra external (step up) transformer.

I had a problem with the 15/-15 fuses on a 106 recently, they were blown, but when powered on, voltage still made it to the other side!! Somehow become semi conductors. With the power off they were open circuit, powered on they passed a low voltage : /
@Xakutor 4 ай бұрын
What blows my "fuse" is the fact that you replaced that one bad fuse with a fresh new shiney one and left the other 3 dull old ones in there... after complaining about the low quality junky fuses that were in it...
