It was a great school for learning radio and TV electronics. Some of the instructors were ex RAAF techs. One of my memorable moments was a tour of the RAAF base the school arranged for us students. The radar gear was the highlight, for me at least.

Mr. Wiltshire, Mr. Drury, Mr. Steele and Mr. Hodgkinson were instructors I remember. Great blokes doing a tremendous job.

You may already know this, but there were plans to tear the entire McKay wing down for some development but locals and ex students from the 60's /70's staged a blockade or protest and won the battle to save it. I read that about a year ago, so I don't know if it's still there today.

Do you remember the link receivers? Amazing AM radios with link connections to each component. The idea was for us students to tune into a radio station then pull out one link at a time before the radio died. At that point we had to write a report on what why how.
It was amazing how many components you would disable and still have an operational receiver. Listening to the quality deteriorate with each link removed was part of the challenge. Wonderful learning years.

HI Folks,

Thanks very much for the schematic Labrat!

Followed the green circuit back and discovered pin 28 on the IC 701 was bent completely back on itself. (like an ugly stick).

I wouldn't have found it easily without the schematic.

Strange as I didn't reseat it whilst recapping. Needless to say the Television has totally come back to life and replacing the capacitors made a huge difference.

Only fault I can see is a slight greenish smudge across the top right corner. Maybe a degaussing issue? When displaying solid colours.

Have bought a cheap HDMItoAV converter and a have a Raspberry Pi set up playing SD files of Leyland Brothers and Looney Tunes and many other SD video files. Plus plenty of old emulated gaming consoles of the past.

Picture is great.

Extremely happy to save this unit from becoming landfill.

Thankyou all for your help

Those names from Sunshine tech really bring back memories.
I remembered Mr Wiltshire but none others until you jogged my (failing) memory.
Sunshine tech no longer exists and is now units, I think.
Been a while since I've been down that way.
I remember all of us discussing cars more than electronics studies as we were young apprentices back then.
I had a split window VW Kombi van at the time.
Wish I still had it now. They're worth a small fortune.

Thanks for the update Irext,

I had a feeling the tech would not be saved, you cannot fight developers, it would seem. Such a pity, the building would have outlasted anything built today.
