GM-100 [Template]

Here is for sale a vary rare GM-100 tube amplifier. GM-100 considered the king of single-end. The biggest and most powerful tube amplifier.

Implementation of this tube is hard and you will not see many amplifiers around.

If you don’t know the tube is 50cm (half meter) long.

The amplifier is build around transformers which is the most important part and most heavy. Two blocks: power supply and the amplifier. The total weight is around 140-150 kilos (please read it again). The power supply aprox 50 kilos. Only one output transformer is about 20 kilos.

It produces big heat. Please consider it.

The amplifier has a mode for the headphones. (Unique feature)

Regarding the sound. Effortless sound. Incredible dynamics. Used on a full range speaker you won’t believe how big is the sound. 10 inch single speaker plays as a horn system full of bass. The bass is the best bass tube amp can make you need to hear it.

Driver tube el55 (very good sounding tube)

50w x2 output power. 10Hz-25kHz 

I am selling it for my friend who is the builder of the amplifier. He made quite many on 833 and gm-70 and gm-71. That one he has kept for himself. This amplifier is not for every one. He is not a commerce person he is more a traveller who needs to take the Everest and all top mounts on earth. You can have this amplifier for 16000 usd. The shipment and the money transfer apart.

For any inquires please write me or call me.

I had only one small deal on the audiogon few years ago but I have over 150 transaction on eBay 100% feedback. 

Please, only serious inquires only.
