Note the strong similarity to the Electravox.
“I had a great 60 watt one as my first amp.” Peter Mullany (ex-Sekret Sekret, etc.)
Pretty sure the OT in them was made by a mob called Telecomponents in Sydney.
Here's one in a Vadis 250R combo with the label still attached ...
Mine is also running on the yellow tap. From memory one tap seems to come from the middle of the windings and one from the end.
As far as dating goes, mine came with a pair of Miniwatt 6CA7 both date-coded B5C5 (5th week of March 1965), All but one preamp valve was dated 1965 as well. So I'm confident saying 1965 or 1966 for mine. My serial is 423.

I looked for ages to find something on Galaxie amps.
Mine looks identical to the Vadis Escort, except it has a GALAXIE sticker (like the br20 in the vadis section on your site) on the front panel. The sticker probably covers Vadis, but haven't checked. I bought it in about '95 from cash converters.
Attached is the schematic.

Circuit for LB60 and LB61 thanks to Trevor Tombling.
Errata (dated 22/10/07): there should be a 100k between the anode of V3b and HT+3;
the 0.0047uF shown at the top of the treble controls may actually be 470pF.

Here are a few photos of my Vadis LB61 extended range. I acquired this amp a few years ago, someone was throwing it out, and I happened to be at the right place at the right time.
[how lucky can you get?! - rr]
After cleaning up the pots ..that's all, I have the best sounding vintage amp I could possibly want, it has a really beautiful sound. The first channel seems to be suited for bass and the 2nd for guitar. I found the manufacture date inside, 4/73.
Thanks to Mal O'Neill, EVATCO.
