Any ideas on how to solve this?

Stupid broken Europa mod that no longer has any support... I believe I fixed mine by fully resetting Europa, but I don't have it anymore so I can't remember the process.

So here's where I am at with the T8 and this problem: I really think it's the Z8002A processor. I originally checked the power supply to confirm the voltages were correct. Everything is good there. However, I did not check the power rails on the board itself when the problem started; I kept a meter ...

That's ok... I used Freeze spray on the offending CPU to see if that changed anything but it didn't. I'll keep poking around.

https://www.youtube.com/watch?v=h6nrr2EJSkw&feature=youtu.be I've included the issue and also I'm showing what happens when you hit the tune switch. Then just a general overall pan of the CPU and voice card boards. So recently, another issue cropped up where as the synth warms up, I suddenly only g...

Seems like it was a rebadged Vox piano also... wow. So this thing has been around the block as a generic analog piano....

The flanger piano might be cooler... if anything else, curious to know what chips are doing the flange...

I picked this up at an estate sale last weekend... $15. https://farm1.staticflickr.com/913/43593781261_d5f94c3c13_z.jpg https://farm1.staticflickr.com/939/42689152545_bb7c42ceba_z.jpg https://farm1.staticflickr.com/934/43593780021_9b47b2acd7_z.jpg Yeah, it's nothing special, it's a divide-down organ...

Wow, no way... I remember peeling through that Novachord restoration page years ago and seeing the amount of work needed to get it going... good score man.

Here's my latest, $200 Smokin' Deal... https://farm2.staticflickr.com/1827/28143170857_c688f7795a_z.jpg https://farm2.staticflickr.com/1772/28143170657_b50f48bc47_z.jpg https://farm1.staticflickr.com/883/28143170637_015e8a2419_z.jpg Needs to be tuned and some random OCD things fixed, but it is in ot...

Wow... Novachord. Is it fully functional?

That's not a bug- it's a feature. Yeah, I think I was able to finally understand that now that I've gotten to play with it a while. I was actually going to post an update on the issues I am having with it still, though they're not deal-breakers. Just wondering what could be causing a couple things:...

At the risk doing more damage but realizing it doesn't work anyway, I decided to pull the 2 op-amps (LF356N and 353N) on the output board and the CEM3360 VCA. Powered on, got nothing. No hum, no feedback. Ok, good. I put the VCA back in, powered on. Works! Get sound, everything works it's just fairl...

don´t you have the schematic ? Make sure you choose the correct reference points. Chassis will not work as a ground reference here. Apart from the regulated voltages the PSU also makes the unregualted DC of both rectifiers available at the connectors. that would explain your 49V. br Arne I do have ...

I still haven't gotten around to recording a good sample of the T8 for comparison... Last night I re-capped the voice cards and found no difference. I wasn't really expecting one, but it was worth it to me to change out 32 aging caps. Tonight I decided to finish the recap with the power supply. That...

I replaced everything on the output board... A complete re-cap is in order, I had already replaced the caps in the funky voice but I noticed the caps they used originally all have different markings and look like they face all different directions. I’m pretty sure if I do a connectivity test between...

Just an update to my Prophet T8 - I was having issues with two things, one being that the overall sound seemed overdriven, and two, there was a static "pop" coming from somewhere that would appear in every couple notes, or so it seemed. I was able to track down the pop to voice 4 on the left-side bo...
