Converting sweep tube amp to 4cx250 amp
Just finished a project of converting my old 4 sweep tube amp to 4cx250. I f
the amp uses a doubler type power supply forget it. Might as well build from scratch. Bridge type power supplies can be converted to doublers that will give about 1600 VDC. At this voltage power out of the 4cx250 will be about the same as 4 sweep tubes. Im getting about 800 watts PEP. Dont even think about running 2 4cx250s, OF course you could but the rest of the amp parts will never handle it and again you might as well build from scratch. |
