Because of the sheer size and mass of these amplifiers the units will have to travel palletized via FREIGHT. A truck with a lift gate will be required which adds to the final cost. Price in non-negotiable. *** NO EXCEPTIONS***

Questions for the seller |
|---|
| If I only use Kt88's do I have to adjust the bias when replacing tubes? The manual states: "Bias (Manual) - adjustment when the tubes type is changed"
So, no, it is not necessary to re-bias unless you change the output tube type. If you stick to KT-88, you're golden.
Also, these amps have recently been thoroughly gone through, tuned, and even re-tubed with brand new Gold Lion KT-88 tubes by authorized Jadis service center Brooks Berdan, Ltd. of Monrovia, CA. |
