I have wire-up my first ever DIY with DHT tubes.The preamp which use one old Osram LP2 per channel.I have DC heaters supply and also have hum pots.The preamp is little noisy but but this not realy bother me.The problem is when I try to turn hum pots I get cracking noises in the speakers. Can anyone tell me why ? What I do wrong ? The old LP2 tubes are microphoinc like hell but sounded fantastic. Thanks for any sugestion. Joe |

That always puzzles me why circuits show hum pots on dc filaments too! |
