| Supratek Owners Thread My particular 101D Cabernet unit has not a small noise from the power supply. The HT lines had about 20mV p-p ripple and the DHT filament DC supplies had the same amount. It was a scary to work on the power supply so I decided to work on the main ... | |
| Supratek Owners Thread couger4u: if you turn down the gain and turn up volume, and reduces the hum and noise. That's probably because the hum is power supply related. My Cabernet has the same characteristic. I used to run the Cabernet 101D with lower gain with higher vo... | |

| Supratek Owners Thread I was referring to the b+ filtering cap for the DHT filament, which was soldered in reverse. This obviously would fail to work for its intended purpose of smoothing out ripple. I believe what my eyes see and you are just speculating that it was mo... | |
