Hammond organ amplifier, all original components. No modifications, all factory with the exception of tubes in which two were replaced at some point, one of the 6BG5/EL84′s (replaced with vintage RCA) and the 12AX7, replaced with vintage Mullard? Based upon the ribbed top, but not certain as the print in nearly all gone except part of the 12AX7. This unit was salvaged out of a Hammond, A-105 Organ which was headed to the landfill, I managed to talk the owner into letting me salvage the parts before he took it away. I have no idea if this works or not. Hammond AO 39 Power amp. Tubes 4 (1) 12AX7, (1) 5U4, (2) 6BQ5. Use DYI EL84 guitar amp or Hammond organ replacement, or great HiFi project. The AO 39 was used as the power amp for A-105 series organ driving two parallel connected 12 inch speakers. The amp is a good candidate for conversion to several EL84 guitar amp that use one or two preamp tubes. The chassis has plenty of room and will easily handle two extra 12AX7 tubes.
