Hi,
I did wonder if it was an Akurate Kontrol, however Google AK/1 preamp and I got something completely different.
In answer to the OP's question if it is an Akurate Kontrol then yes along with a Klimax Twin, which is a great amp, it will drive any speakers with ease.
I have the Linn 2250 with the Dynamik power supply and I am told that it is basically the circuit of the Klimax Twin, just a different box.
Not sure if the early Klimax Twin had the Dynamik power supply, however the difference between a non Dynamik 2250 and a Dynamik 2250 is quite marked so I would assume the same would hold true with the Klimax Twin.
Cheers
John
