Well, here we go..........
Ladeez........... an ..................Gentlemem!,................. at great expense to the management we bring you , in the main ring for your very eyes....................

It did seem like a circus production, but I have FINALLY finished off this set.

In this last episode I jam the chasssi into a wooden box, slop totally inappropriate paint all over it , make a mess etc.
Also I tame a cheap Russian TV tuner thing, glue that in and let that drive the valves to show a cute picture up front!

As always learning along the way.


Fred.

With a green screen, I guess on Mars it'd be classed as a coloured telly! I wonder how it'd go watching episodes of Lost In Space.

A valve a day keeps the transistor away...

LOVE it, Fred! That's a nice way to treat the STB, it actually looks the part!

Remember the Clunk - Clunk rotary channel knob idea, interfacing to the IR of the STB? I still have a Philips tuner sitting here, and a programmable controller card that can read the binary coded biscuits and send the required IR code sequence, waiting for the go-ahead from you!

Thanks Brad and Ian.
The set nearly turned out looking like an actual piece of real equipment.

It needs details fixing like the paintwork and some panel markers like brass or traffolyte plates riveted on for the controls.

I might get a second wind sometime and fix that and yes Ian when I get a third wind and look again at my 5BP1, 5" set your clever idea with the coded card and the philips tuner would be far better than the ex Jaycar STB I have hanging off the front at the moment.

Brad, the quality of the picture on this baby is: Its better to close your eyes and just listen to the sound only!!!
(although I guess if you saw this in the 1950's it would have been a world wonder!)

Fred.

"bits and pieces not out of place in valve gear!"

no surprise there considering a magnetron is a valve!

Absolutely fantastic work there Fred!
what CRT did you use?
I definitely would like to make a TV like that one day.

Hi Burnt out,
May sound odd but I do not know what the tube was exactly!
Have a look back around 23 Jun 2017, "fred Levers 3" TV set".
Scroll down until you see the post about CRT tubes.
I tested a bunch of unknown tubes and worked out how to light them up, then picked the best one.

I did leave enough room in the design to use a known rectangular CRO tube.
However I never worked out how to remove the graduated scales on the face of the tubes!.
These seem to be imbedded in the glass front of the tube.
Not exactly what you would want to be squinting through to see the picture!

I worked my systematically through each section of the TV and made stuff work.
Knew very little when I started but knew a bit more when I finished.
Especially what the PAL system was was.

Fred.
