SOLD: Antique Sound Lab MG Head OTL Mk. II  tube headphone amp

Can you tell I'm moving away from headphones? A very nice sounding tubed headphone amp.


-Transformer coupled or transformerless (OTL) output

-Two inputs: one miniplug and one RCA.

-Two front headphone jacks

-Polarity switch on the power supply (IMHO, no sonic difference)

-Separate power supply with selectable polarity inversion

-Tubes: 2 EL84 type, 1 12AX7 type (currently Sovtek & JJ Tesla)

 

There is a selectable feedback switch on the rear of the unit which is always on, but momentarily selectable to off. Again, I have never heard any sonic difference.

 

The difference between the OTL and transformer-coupled is obvious: with the transformer setting, bass loses fullness and the treble becomes slightly harsher; the music becomes more “aggressive.” Switch it to OTL and the sound becomes warmer and more natural, with slightly less gain.

 

The are no sonic issues and it is a delight to use with its adjustable settings. There is a bump to the upper left faceplate. It is deceivingly heavy due to its transformers; the power supply weighs three pounds and the head unit about seven.

 

$250 including shipping to you in the lower 48. Please email any questions. Thanks.

 

Mike
