Symptoms: When your head is at the optimum position for actually playing or programming the synthesizer, the LCD contrast is not quite right – it is washed out and pale, and the contrast knob on the back of the keyboard does not help – turning that makes the display go from completely white to pale colours but visible text, whereas when viewed from the above it is lush and blue with very nice contrast.
… aneb jak zvednout výkon, snížit spotřebu a zachovat spolehlivost.
Ford Transit Mark 3 se (podle wikipedie) vyráběl v letech 1986-2003. Hodně těchto vozů bylo poháněno atmosférickým dieselovým motorem o objemu 2496 cc, jehož sací potrubí připomíná svazek banánů. Ne nadarmo se v Británii používá termín “banana engine”. Tyto motory měly mechanické čerpadlo Bosch, byly velmi spolehlivé, ale strašně líné.
As I work in repair center, I could not notice many Line6 DT50 amps with short winding in the power transformer (secondary HV). These transformers are currently out of stock. We decided to manufacture new transformers by ourselves as we can make them better than PRC.
The main cause of this fault is bifilar secondary for 2x258V. These wires conduct high voltage and they are located all the way next to each other. Do not wind up secondary as bifilar.
Mains Transformer LINE6 #11-30-0045 datasheet is located below if you want to make your own. We did not, however, count all the turns of all windings as it was difficult without proper tools. You have to calculate the turns by yourself. Anyway, the datasheet gives you a clue about voltages and color codes.
I have developed this interface in 2011 because I had two M-Audio DELTA 1010 sound cards at the studio, gathering dust. Later, it seemed to be good idea to sell them. But I have never managed to make and sell many ADATERs therefore the price stayed too high.
