People ask me if I am nuts trying open a shop in Russia. Yes, no doubt, but why else would I be in Russia and actually enjoy it immensely.
One of my pet peeves is very other unit coming in for work has been worked on previously. Usually by people calling themselves "Masters" working out of their apartments. For some reason, most of them try to modify even simple circuits if they can't get it going. In doing so, they ruin the value, functionality and reliability. Here is one that came in today, from a kid who just picked it from another "master" and was charged money but it did not work. He said he bought this Kustom DE300HD new and this was the first time anyone worked on it. The original symptom was a strange noise when turned up past "6".
The preamp board had a new IC installed on wire legs to stand it above the board. The power amp had parts hanging loose so I pulled the board and heatsinks(only 2 transistors were screwed to the heatsink) and peeked at the bottom of the board.
Most of my work in the last year has been trying to recover a bit of value or functionality to units that unsuspecting customers were cheated out of. The strange thing is that I am the only one who gets angry over this sort of customer abuse, the customers just shrug their shoulders.
I am going to try to recover this one to working status. There must be 50 copper traced burned off the board due to excess soldering heat. There is no indication that there was anything wrong with the power board in the first place.
Anyone have a schematic for a Kustom DE300HD?
