Re: New HT5-R - No Sound!

You must open the amp and compare pcb's... If they are same then is very possible to have the same problem and the solution could be same :)

Re: New HT5-R - No Sound!

This is how I did solve this common blackstar HT-5R problem ! I really don't know how is possible blackstar make this mistake in HT5 series... mosfet's without heatsink ??? Changed: both TR2&TR3 with 8N80 (6N60) on heatsink fitted on the chassis, both 22K resistors, FET J175, A7 diode below R51, R10...
