Interesting 15 Watt Tube amp with “power scaling an over drive and compressor Nice low power Jensen SpeakerPooor workmaship on the grill cloth fixing.. not enough staples.. leaving a wavy line pretty poor for such a priecy ampEH tubes branded fenderOne dead tube… I hope this is the only issue…Sovtek TubesDual Solid State Power amps!New tubes in a quick bias check and all sweet!Back on drop in voume using the effective solid state reamping (8 Ohm dummy load on the real tube amp) crank it till it bleeds and listen at bedroom volumes! Compressor and Overdrive good too!! Interesting 15 Watt Studio amp… with the most semiconductors I have seen in an amplifier recently. Hugely complex power scaling feature..only real issue was a dead output tube. All serviced she really does sound great! and the power scaling feature works well as does the compressor and overdrive. Great amp.
I have one of these, but it has the (apparently) common fault of the amp cutting out after a few minutes use of the attenuator, seemingly triggered by more aggressive pick attack.
Any ideas on what needs replacing to get it working again? Works and sounds perfect when not using attenuator…
Mmm the attenuator itself is passive (actually just a resistive load not really an attenuator.. 100% attenuation) and unlikely to be the issue. It is then fed to a solid state amplifier.. I do not have an idea of what oculd be wrong, I would really need to see the amp. Sorry
