hi. welp, after 1/2 year or so... and 3 shipments to me... i finally have a working MG Head! my modified amp just arrived today.
so far, nothing major is defective. only strange thing is, when i sent my mg head in to be repaired/modified, the feet were even on that particular unit. when i got it back, one foot was about 2mm off, so you could still rock the amp around. interesting.
but anyway... after ALL that trouble i went through, this is pretty minor. on my first unit, the feet were REALLY uneven...
so... on with the mods. ...the following mods were made by Mr. Dealy of Holm Audio:
1. gold plated tube sockets
2. GE caps (Dealy swears that despite their low price, they are the best caps he has ever used) --only for the two main caps in the signal chain... the filter caps were not changed. Dealy seemed to think they wouldn't make a difference.
3. Alps pot
4. Blue LED
5. Coax cable for the power connections, with the shield grounded
...and the result? well... i cannot be too sure, cause it's been so long since i've used my original... but there is one very clear difference: the buzzing is gone for normal listening levels. the amp is DEAD silent up to about 1/2 rotation of the volume knob. ...but after that, you get increasing buzz... and a little hiss. at full rotation, the noise is too loud... but unless you have a headphone that's crazy inefficient, you won't ever turn it up that high.
...he did charge me quite a bit... $190! heh he... i know, that's pretty high. but at least i have a good amp again.
so, in the end.... total price to me is $500, not counting shipping half way across the U.S. 3 times.
.....now... i truly think that ASL should have raised the price in the first place, if that's what they need to have good build quality. if they even had to raise the price by $100, it still would have saved me $100 in the end.
welp... i'm listening to some music off the MG Head right now with the HD600's... finally finally finally.... audio bliss.
