This Orange TH 30 looks like a British built amp but is made in the PRC like so many modern amps these days.  As such, it shares the same "feature" of every wire connection terminated with a spade connector.  These often make poor and sometimes intermittent connections and are a cause of all sorts of problems.  I hate them!

That said, it's a heavy beast with decent looking components and a solid build quality.  It features 2 channels clean and dirty, has 4 different power settings, with a three position standby switch offering full and half power, and on the rear you can switch between 2 and 4 power valves.  This makes it highly versatile.

It had a broken jack socket and the drive channel hummed a lot, had poor volume and the tone controls didn't work very well.  I tested all the pre-amp valves and one was significantly weak.  Replacing that cured the problem with the dirty channel.  However, whilst chop-sticking around I noticed some glitching on the scope.  A couple of those spades were loose so they all got to feel the heat of my soldering iron.  Whilst in there, all the tube socket joints to the PCB were reflowed, adding a little extra lead free solder to each just to make sure.
 
As the input jack socket is fixed to the PCB and I couldn't find an Orange replacement part, the loose ferrule had to be bonded in place.  Superglue is not appropriate here so I used a solvent based contact adhesive.  This dries like rubber and is strong enough and flexible but will allow the ferrule to be removed if required.

All in all, not a bad amp with a great clean channel and some seriously raunchy overdrive!
