Nice and simple inside.not much to go wrong. What's the line of splodge running down the centre of the heatsink,or is it two separate heatsinks meeting at that point?
Be seeing you.

This will be the 5th one (out of 5) that have been BER.
The last 4 had caught fire and this one has all the mosfets blown and the bus capacitors open circuit.

The two heatsinks have a bead of silicone down the middle to seal them for the fan

I'm glad that was answered sensibly and someone with, let's say, a childish sense of humour didn't suggest Kevin got exited over McGregor internals.

I'll get my coat.

I dont this this one does, that would be the original melksham citronics, ie the original company. This amp is really a McGregor, I think probably made after Skytronic bought the name.

Citronic PSX4. I was quite expecting a Skytronic innards and got ready to grimace, but was pleasantly surprised by a real Citronic.

Those old PSX4’s are almost bombproof. A friend of mine had 4 of those in his hire stock from the mid 90’s until around 2010. I once worked out each had earned over £20K in rental fees!
