Pushed, it started pulling. Push pull. Push pull.
Was about to unplug when a thunderous "NO!" came from the speakers.
With authority. Presence. Never heard it so forward before. My ears were ringing. Or was it the tubes? Sliding damper on, I could swear the amp began to hum. With pleasure. Liquid. Not syrupy, silky. Silky smooth. Yet at the same time, exciting. I slid another damper over a tube. This time, input tube. All the way. Really silky liquid now.
It runs hot and cold a bit, but I think I may be in love with my amp.
