Triode Corporation Japan

TRK-3488 is designed as a tribute to the 15th anniversary of the Triode Corporation Japan.

We look forward to making a return to the basic values of the triode TRK series as originally debuted. The concept is a Class A design that can use either EL34 or KT88/6550C to enjoy the splendid sounds. This amp automatically adjusts its bias system.

The contents of this kit is complete. Just solder the components to the printed circuit board, install the chassis wiring board and you’re almost done. Tip - all input, and volume control wiring are pre-wired. Average time of creation is 5-6 hours.

Kiwame resistor or Vcap upgrade is available.

Does anybody know how I can get one of these in Norway? Or, how much transport will cost me if I buy from Canada?

There is a distributor in Norway. Please contact the distributor in Norway

Thanks vKung (and also thanks for your pm)

Do you know the name of the Norwegian distributor? I haven't found any and they are not listed on the webpage of Triode Corp. I have spoken to the company that Triode Corp lists as their distributor in Sweden, but they no longer sell Triode equipment.
I have also tried the Danish distributor, but they seem to no get hold of the trk.3488 model.

Thanks again!

all the best,
