Hi there.
Previously I posted a thread about a head I bought for £30 earlier this year. It's a Titan TA/50A, and I have no idea what it is, nor did anyone I asked here.
It was suggested that I take some photos of the inside for people to see, so that's what I've done (Now that my camera finally works).
Okay, first is the left side of the amp. The Pot closest to the camera needs replacing, as it's a switch. But it no longer clicks, so I'm unable to turn it on..: 
Next is the right side, no idea what anything is here: 
Here's an overview of the inside: 
And finally, can someone explain why there are three jacks on the rear? And why they're labelled what they are: 
Thanks a lot everybody, Anthony.

Today we would label it "line out" or "Preamp out". That's just a guess though, be careful connecting anything to it.
The big square thing is a transformer and the three big cylinders are filter capacitors, all parts of the DC power supply. The board mounted vertically next to the transformer looks like it has the power transistors on it, so I'm guessing that is the amplifier circuit. The fact that the transistors are not very large and are not connected to any kind of a heat sink suggests this isn't very powerful. The other board mounted on the bottom of the case may be the tone control circuit.
That's all I can do, and I may be wrong. I'm sure some EEs will weigh in with more info. |

As already suggested, I wouldn't put a whole lot of time, money, and/or effort into this one.

Thanks, Anthony.

| The board is just a driver board of the power amp and there are indeed power transistors connected to a heatsink, which in this case is the rear panel of the chassis + two pieces of metal bent to U-shape; You can see four fins of those two sinks and two TO3 case power transistors mounted on the rear panel.

| More likely the entire preamp.
