I think I had the idea of building a Luxman-clone based on the rather rare 50CA10 power triodes. However, in the shipment from the Netherlands came a broken tube, I decided to use a pair of transformers intended for GU50 Single End. Since then the transformers have been sold, the project scrapped and the GU50's will propably end up in my Priboj amp.
From some other places I have now obtained a complete set of 50CA10 and also have some spare, why I will continue with the Luxman.
But I hade this 50CA10-SE up and running and playing as loud as it could - perhaps 7-8W.
