Wow Great info MJMP!!
Same noise from both ODs
Attached some pictures from bottom of the unit.
I am bit worried with these mods, I would prefer to have the original unit.
Based on your experience can these mods be reversed?
Of course if there is a modification based on the ADA specs like that letter from 92 where ADA recommends some modifications for older units. I guess this one is applicable.
Glad to see its from the first 100 batch!! Thats quite cool.
I am indeed worried with the poor job done. If you see some pictures some solder is very poorly done and there are cables with wires not included in the solder joint which look dangerous...
I would be interested in putting this unit beck to stock, however i would like to keep what you think should be kept. For sure the transformer as you mentioned.
But regarding these mods... I am not sure. I have to listen to it. I really like the Nuno Bettencourt, Vitto Bratta sound and not so much Paul Gilbert. Not sure if these mods change the unit sould a lot. I will investigate and hear some demos on you tube.
There is also the noise mod, maybe that is beneficial. Do you advise this one?
I think i will start by checking that input jack, if you agree, and then move on the check the capacitors and replace the inadequate ones. I will have a look at the mods schematics to see what was modified.
Another option is also to send it to you for repair, if you would be available for that. But i would like to first have a shot at understanding whats wrong with unit, with your help.
I noticed also the volume knobs should be blue in the original? but these are all black. Could be that some units came like this?
Thanks again for help and sharing your knowledge!
