Getting better now!

I replaced C119 (small black Hunts .01) and C118 (blue Dubilier .03) and all frame controls are now fully functional. Contrast and brightness controls both work but could do with a bit more variation than they're giving at present. This will probably improve when I replace a few of those grumpy looking old caps on the IF board. The other thing that will help is finding the correct attenuator to use on the Domino for this particular set. There's a lot of signal.

Going back a couple of posts, I notice that there is a U position on the 405 tuner. It doesn't switch standards as there's a 405/625 system switch on the left hand side of the cabinet.

What a palaver eh! Back in the day, to get BBC2 and look at the lovely Victoria in The High Chapparal, you had to switch to 625 on the left hand side and then put the 405 tuner to U and then fine tune the rotary 625 tuner.

Happy days.

More soon.
