Hi Dave, I have the exact same turntable, I got it off eBay a couple of years ago , for £17 without a cartridge and it was running slow and the pitch control wasn’t able to provide enough adjustment . I found a KZbin video on it and after adjusting the two pots I got it working replaced the cartridge and it’s been working fine ever since, really great turntable. Were you trying to find the hidden message by spinning the vinyl backwards?

[@incompletefool9513]

Thought it was The Exorcist!

[@marka1986]

Wonder if KZbin would give you a copyright strike if you played music backwards

[@Godzilla941]

Marcon capacitors. Oh joy. I have a bunch of those in my capacitor junk box from an IBM PC power supply and for giggles I tried reforming them (at microamps) and as they got close to their rated voltage they all cascaded to hard short circuit. They don't like sitting unused for 25 years. :)

[@TurntableGuy]

Had the same table in for repair once. Changed out all those Sanyo caps. The main issue was the .47uf cap and a couple resistors in the speed circuit plus a dirty speed switch and of course, the pitch pot.

[@12voltvids]

Those Santo solid caps were problematic on Sony betamax back in the day. When i worked for Sony I changed out every Santo solid cap for another brand of tantalum. Not all would go bad but they failed in high enough numbers that they were changed. It was an assembly fault that caused the failure. Bend the leads and they break internal.

[@gamebay100]

Where could I buy a meter like that? I am working on a Denon DP-33F right now and I think it might have bad capacitors. I guess with a meter like that one you don't need to desolder the caps from the board?

[@danmackintosh6325]

Think your speed (and direction) were drifting a little around 9:54 as well Dave! Was it an editing faux pas or a rock music "play it backwards" subliminal message though? lol (And do I now have to press the audio track onto vinyl and ruin a stylus running it backwards for the message to come through? Because YT don't support reverse play to my knowledge)

[@danmackintosh6325]

OK I'm up to 13:56 so far & it's pretty evident it's no slip of the mouse in post! Got me wondering now, might have to "reverse engineer" the audio later. Noticed some video strangeness also, but not tied to every audio flip.

[@rawr51919]

@@danmackintosh6325 There are turntables out there that can reverse the motor direction and play backwards natively with a special stylus and cartridge

[@danmackintosh6325]

@@rawr51919 I don't doubt it, but your average rocker/metalhead wouldn't have had such kit back in the day (That was the reference I was making). Now you've piqued my interest though, could you suggest a TT model to look up and see what's going on with them?

[@rawr51919]

@@danmackintosh6325 Not sure what models do that exactly either but I know they're out there. There's at least one KZbin vid that shows one in action to play a backmasked section of vinyl the right direction

The speed of your voice was changing goes right along with the turntable problems.

Yes! I was paying attention! And congrats on getting your Play Button.

[@mrfrog8502]

4:50 It's a two phase motor not three phase. Motor block has 2 coils, 2 hall sensors and phase feedback coil.

[@12voltvids]

You sure about that. All the DD table motor schematics i have looked at they are 3 phase drive.

[@zx8401ztv]

Yep switches and pots/presets are a pain in the arse!. The rivits at the end of the pot track are a problem with vibration. I have a dislike of old wire wrap pins, i solder the top few turns for stability.

[@SPINNINGMYWHEELS777]

I've never had an issue with the wire wraps but I do give a little weld of solder as well.

[@zx8401ztv]

@@SPINNINGMYWHEELS777 Don't get me wrong, new wirewraps are great, but over the years damp gets in to them and even though they are fully wrapped with wire i've have had problems with the connection. But some units never fail. Bad solder joints on components are far more unreliable.

[@SPINNINGMYWHEELS777]

I would have went for the speed control and those swtiches first - out of my experience with Technics 1200MKII drifting over the years - have to recalibrate the pitch slider - I know it's not the same turntable - but similar problem - cheers sir - good fix !

Dave have you been testing us with the over dub's, playing them backwards. OK, you got me. haha

[@darinb.3273]

@@12voltvids Indeed I learned a little bit about how vinyl is recorded really quiet parts the audio is raised slightly to go over the noise floor and louder portions reduced somewhat to stay within the limits of the vinyl itself, which is absolutely unnecessary with digital.
