Hi Sparky,

Wonder if that Vestel Power/Invertor is used in other sets, a pic would be nice for the collection.

Thanks - Chris.

PS - for fun attach another that is giving me real pain - any thoughts ?

Hi Sparky,

Tend to take pics intially, possibly due to my lack of confidence in getting all the plugs back in the right places.

Used to be the case where other local technicians, finding my foul-ups would demand a pint locally, or broadcast my errors to the locals.

Last to the bar - Chris.

Hi Sparky,

Troublesome as ever, but with an improving data-base. Who made the L32U25 - 200C P/S ?
Well folks might want to know, and you might be first to the bar - yet again.

Chris - only on tea - well it's cheaper, only half the price.
