Thanks Salas, yeah that's what I was afraid of with a more powerful transformer. So, maybe I'll try the Hammonds. Thanks for your help and thanks for the design. I've got your FS phono preamp lined up after this!

In the case of 50VA and 100VA Anteks their difference is mainly in height so the bigger ones don't take much more chassis floor estate. But going for 2x200VA double mono... no, too much.

Back in post 2054, I had broken a drill bit in the hole for the 1/4" headphone jack. Thought I would just buy a new front. Instead enlarged the hole to about 50mm, which removed the broken drill bit hole and added a 4mm piece of brass to the mount the jack. Problem solved.
Now to enjoy!!

Nice brass patch idea. How is the thinksound headphone doing on this amp? Is it the On1 or the On2 by the way?

Thanks Salas. I have come to really like the sound of the Thinksound headphones. These are On2 bought through a Massdrop purchase.

For on ear type I have kept two old models. Grado SR60 and Sennheiser HD40. Mainly to can test 32 Ohm and 600 Ohm loading because I don't like the feeling of headphones sitting on the ear for too long. They usually don't achieve a wide image too compared to over ear ones. When it comes to travel the on ear type is small and light though, very adequate. Remember the massively popular Koss Portasound of yore? Still in production for those reasons and a good balance on the cheap. The Thinksound looks much more advanced and well made though. At Massdrop price a bargain. Although Massdrop's best bargain in absolute terms should have been their HD6xx runs (custom color Sennheiser HD650).

By the way how's the image of the On2 when on the DCG3? I have noticed that my on ear 'phones sounded wider on it than when directly fed from the DAC's headphone output.

Does bass but does not do much sub bass, has great HF extension but not super fine treble texture. Does not have modern looks, has vintage pro looks. Has roomy pads and light weight. Its built to last and to easily service. Made in Germany.

The cable is detachable with a proprietary flat connector. The right channel phone has six female pins and it attaches there. There's a metal threaded insert on the cup for securing the connector with a provided screw through an eyelet on it. The three meter cable ends in a mini jack with a quarter inch jack screw on adapter.

Two of the pins should be for an optional microphone because they showed nothing on the DMM but the remaining four pins on the cup showed separate ground return connections between drivers in the continuity rest.

A unique looking and sounding phone in the mid-low price closed back category. Excellent value IMO.
