Me and the 1210 are gunna have us some me time....

Andrew,
Martin is absolutely correct, you must try to find out what went wrong before possibly repeating the 'orrible' exercise!.
Examine the PCB carefully and check each connection. Switch on the power whilst the platter is removed and check voltages at the 21V module. Check that the +27V is going to the correct terminal. Check the actual voltage on the wire.
Check the +9V and +5V outputs.

Before doing all this check that you have the + and - leads of you voltmeter going to correct terminals on the meter. (it can happen!!)

It maybe that all you have done, is to blow up one of the sub modules (9v or 5V)
or perhaps they are producing the incorrect voltage??

Now check the voltages at the PCB.

When soldering: always take the solder to the job.
Never ever melt a blob of solder onto the tip of the iron and carry this to the solder point.

The reason is that by the time you get the blob of solder to the job all the resin flux will have evaporated away and you will get a "dry joint".
I have seen countless problems caused by this.
It is very easy to secure the wire into the holes by bending over the ends if required before soldering. Although you will need to be very carefull doing this on the sub modules as there is not much room available on the very small solder pads provided.

RIGHT! You have all spurred me on to diagnose what went wrong. I suppose it's a good exercise for the future. I'm supposed to be finishing off my MSc this weekend but a little time spent with the deck could be found I suppose

Shame you're so far away, Andrew, or I'd take a look at it for you.

[Wakefield Turntables]

Thats awfully generous of you, I'd get you to star earth as well at the same time. The disection begins tomorrow.

PS I've edited my sig to make light of the situation.

Gentlemen I'm back in the land of vinyl. Reinstalled the SR7XL now running at 21V will do the internal regs again at some point next week.

[MartinT]

Ah good, glad you're playing again. Plenty of time to regroup, take a deep breath and try again.

[Mike_New]

Are you now running on a new PCB? or the old one.

[lurcher]

You are not that far from me (Halifax) so if you need another set of eyes to check things over just shout.

Yep thats what I was thinking! I have 30 albums worth of stuff to listen to before I try those again!

Are you now running on a new PCB? or the old one.

Yep its a new one. Only removed the basics to get Paul PSU working again

thanks mate! I dont like to hassle people but I might just take you up on this if I get stuck again. I'll try hard not to

I awoke at 5:30am and whilst lying in bed and staring out of the window at todays shite weather and longing for warmer climes, I started to ponder on Pauly's psu unit for the Tekko. I thought, sympathetically, that Andy (REXTON) must certainly have dropped a brown skittle or three when he, quote: 'completely fucked up' his PCB.... I feel for you Andy, truly truly. Now with this in mind I started talking to myself, inspite of the missus telling me to 'shut up or get a cuppa tea'. This is the crux of my thoughts:

1. Why can't I JUST SEND the PCB to Pauly H?
2. Said Pauly does the necessary surgery on the PCB.
3. Pauly solders the goddam wiring onto the PCB and eliminates unwanted bits from the PCB.
4. PH then identifies and colour codes the wiring to where it/they must be screwed into connecting terminals (matching colour code).
5. Sends the circuit board back to the anxious and grateful customer.
6. The grateful customer could then connect everything up, paying due attention to colour codes and any other instructions, with the priviso that the grateful customer isn't a complete dingaling and can't even use a knife and fork, or flush a toilet
7. And finally, Pauly makes a charge for his help and time and presents his bill.

Just my musings at 5:30am on a rainy day whilst my missus has resumed her snoring, folks
