Difference betweeen Aragon 4004 Mark I and Mark II


Does any one know the differences between the original Aragon 4004 and the Mark II ? Any help would be appreciated. Thanks.

Another difference is the use of a bias system that adjusts itself to changes in line voltage in the Mk II.

This is the first I've heard of flaming resistors!
I had a 2004 Mark I for over 10 years and never had a single problem with the unit. It now serves duty in my brother's system, continuing to function flawlessly. You can check with aragon about the difference. They have very good customer service.
If I am not mistaken, I have an add and the stereophile review and it does mention that there are some 36 new parts added to the mk 2!

Good luck
