I don’t know much about this device. I’ve had it for about ten years and used it with my KEL84 until recently. The best I can say is that in all the time I used it, I never gave it a second thought. It sounds great, it’s been totally reliable and it’s built like a brick you-know-what. Pity it’s pig-ugly...
It’s a studio phono preamp with variable gain. Outputs are by RCA or XLR, the latter being fed through a couple of nice little Lundahl transformers.

The only reference I can find to it on the net is here: https://www.canford.co.uk/Products/2...d-XLRM-outputs

I’m looking for £50, collection from South Devon or South Somerset, or £10 p&p.
I don’t have a mains lead for it.
