    Blackstar HT5 Repair

    Hi there, haven't posted here for a while :/.

    My HT5 has gone very quiet and is you can only hear it when the volume is turned to max.

    I opened it up (Yes, I do know what I am doing) and checked the voltages on the tubes and power supplies - all looks good (~350V for HT, 12.6V for heaters). The sockets are all switching properly too.

    The best solution I can come up with is to replace the pre amp tube and see if that works. If that doesn't work I might take a look at the input stage. Does anyone have any other suggestions as to what it might be?

    Sounds like it very well could be a preamp tube. They're cheap too so I'd try that first.
