Samway DXV500ZS linear amplifier repair (2025/02/28)
February 05, 2025andFebruary 23, 2025I wrote in my diary of I had parts sent from Japan to replace them, but they wouldn't turn on. So I consulted with him further, and he said that the FET was most likely short-circuiting.
Samway DXV500ZS
Board with power FETs
With 6 FETs C2M0160120
I had to use a soldering iron to melt the solder on the legs one by one, and pull the legs off the board with radio pliers.
I checked with a tester and found a short circuit between the gate and the source. The cost of 6 units at 1580 yen each is 9480 yen plus the EMS shipping cost, which is a painful expense.
It is sold at Shopee, a mail order store in the Philippines, but it is rather expensive at 805 pesos (about 2,150 yen) per piece. I will be purchasing from Samway.
