Used purchased it. We improve a high pressure part or addition of an ON OFF timer. Butr, we start a feeder and heat loss of a connector if SWR is high. SWR used it by a high state in 98 and has finished burning a band reshuffling switch. We became contact defectiveness of a use tube heater terminal in the past, but it processed a copper sheet and repaired it. Contact of a CW SSB reshuffling switch isn't sure currently, and there can be a thing starting spark. Because there is a little use with a SSB mode, we think that we will fix it to a CW mode. Reshuffling of CW/SSB changes supply high pressure with a switch of a panel lower part. We will be complete if we establish a vacuum switch. |

We dismantled an amplifier for heater circuit repair. Two of them use use vacuum tube 3CX1200D7 this for a red circle. |
