I just scored one from an old "time capsule" house.
It went into disuse in the 1970s, when the family bought a Rank Arena colour set.
I did the required very slow warmup with a variac, carefully monitoring the mains current. If the electrolytics are re-forming properly, every time you nudge the mains voltage up a bit, the current should first rise a bit and then drop back. 20 minutes of that and it came to life!
Most of the critical paper capacitors had already been replaced by the 1970s and after a reasonable "wakeup" period, the tube produced nice sharp snow, meaning it's still in A1 condition!
Immaculate cabinet.

Yes I have the KGH 1.01 circuit and the differences page that constituted the 1.02 circuit (which does not seem to exist).

Hi Keith and Ian.

I expected to find circuits for HG Palmers sets in my JR Field service manual ( vol 3 1971) but was stumped, nothing.
Then I woke up and worked out the connection with 'Titan' and KGH.

Bingo. It's a "Titan" brand chassis by KGH.

There are circuits for the 1/01, 1/02 and 1/06, 1/07 plus a bunch of alignment and modification sheets.
In the T section on pages T7 to T11.

You learn something new every day!

Fred.
