All I know is my mum bought a nice sony TV because it had those things and 6 months later it was gone.

Thee only thing about so called smart TVs is the support for things like youtube, iplayer etc can just disappear overnight. One minute it all works next its all gone just like that.....

never liked that band

from my experience its the drivers that go not the LED clusters. Cheap oriental manufacturing dare I say?

Thanks Geoff, I was wondering if there needed to be a load on it. Perhaps a 110v lamp or something.

to start with I was getting about 68vdc. I found a manual which gave the procedure for setting up the brake but gave no coil specs. The PSU is supposed to be variable, turn up voltage pot until brake releases, note voltage, turn up 6v more then lock the pot. Unfortunately, after replacing the...

excellent. thanks how did you arrive at that figure by calcs or have you found info for that machine?

no nothing else. 

inside diameter would be approx 4" outside about 6" I would say

Sidey, its been a huge learning curve. I found out today that its been playing up for ages. I have discovered that the 73v ac supply from the transformer at the top centre of the panel supplies the psu via the yellow cables. The blue cables seem to be the contacts to initiate the DC.  The...

Not sure the DC injection braking would work properly on this machine. The motor starts as soon as you turn the machine on. the internal clutch then starts the chuck rotating. The DC would only kick in when the motor stopped. The brake needs to be on every time the chuck stops. there is also a...

it would be a C3 as far as I'm concerned as it was installed under previous regs and was deemed acceptable when installed after all its not retrospective is it?

Managed to find a free download of the manual. Not a lot of help in terms of voltage rating of coil etc. I did find out that the PSU is not working correctly either. So need PSU and coil.

Thanks I'll check it out

Thanks Geoff, not about to pay for a manual, I'm not SE so its up to the owner. I am thinking the semiconductors are some kind of voltage regulator. The power supply has AC on the input side all the time and only when the lathe is running does the DC side kick in to release the chuck. It would...

The power supply in the bottom centre of the panel is for the brake unit. Brake coil is cooked, no information available. Getting one made but they need to know voltage. PSU for brake is fed from a 73V winding on transformer which also provides 110v control voltage for rest of machine. I...

it was early 80's only place to get a CAT scan at the time. Came off motorcycle in N Devon and head not quite right for a while......

Only been to Plymouth the once. Had to get my head examined at a place called 'Freedom Fields' or something like that. Didnt go by taxi though, ambulance from Barnstaple.

looking at a local rewinder repairing it.

turned out ( see what I did there?) to be the brake unit coil cooked. trouble is they are like gold dust so lathe might be finished if they cant get one!
