I have recently built and tested an OTL tube guitar amplifier for my son based on the 1954 Macowsky scheme. There are several tubes: four 6080 (20W final section), one 6SN7 (phase splitter tube), two 12AT7 (gain stage with feedback) and one 12AX7 (pick-up pre-amplifier). I have also used two old PC AT power supplies for cathode heating in order to get ultra-low noise (and to save some money). To me it sounds quite good. I will be glad to share images, technical information and schematics with all interested people. Luca Cellai Rome (ITALY) |
