Was Lasky's an old electronic stores?

What is confusing me about this particular amp is that the writing is all in german, for example for power button is called Netz.

I wired a plug on it before and powered it up, the it lit up rather nicely, if this works I will seriously regret paying £80 for my Sony tuner, as I have a gut feeling this tuner will sound better than my Sony even if it was a basic tuner from the 70's. When I bought my tuner I just wanted everything to be black and mathing, I don't care anymore though what it looks like, getting good sound for little £'s in my main objective now.

Zanish thanks for the other, I am going into town tomorrow so I see if Maplin have them in stock.
