Magnum Dynalab – new ownership

April 2023 – Colquhoun Audio Labs is pleased to announce that we will be carrying the torch forward for this iconic Canadian company. All manufacturing, sales and service will now be part of our Canadian operation in Peterborough and Dwight Ontario. Colquhoun Audio is currently the owner operators of both Bryston Ltd. and Axiom Audio.

BTW - I also have this tuner and it is superb.

Thanks for your replay,

The tuner works perfectly only the magic eye does not light up the tube is probably out.

What I'm hoping to find is the exact type of magic eye used, not the MD reference.for example: EM11 or EFM11,....If I have the exact reference of the tube, I could then check the voltage first to see if the tube supply is correct.
if the power supply is OK, then the tube is broken
if the power supply is not correct, then the tube is OK and the problem is with the power supply

I use a ST-2 antenna and the sound from this tuner is superb!

I send a mail to the Belgian representative of MD I'm waiting their replay
