High power organ amplifier - Ping Bret / LV
I acquired a couple of stripped-down organ amplifiers. There is no brand
info, and no tube markings (and not tubes!) But the iron is massive. Bret or LV: Do you know any tube organs that used (8) 6L6s in a single amplifier? I am trying to get an idea what the power XFMRs might be rated. Thanks |

Thanks I don't think that's anything Hammond or Leslie ever made. 8 6L6s ought to be good for at least 150W in push-pull AB, though. Many organ amps are multi-channel, either for biamping purposes or for dedicated stop channels, i.e., flutes, tibias, rotary, stationary, etc. Do all of those 6L6s feed the same output transformer?

It is probably a PA amp, unless it has the 5 and 6 pin input and output connectors peculiar to Hammond (not Leslie) tone cab amps. It's also possible it was for a big juke box installation. |

Definitely not a jukebox amp. They didn't come that big. Names or part numbers on the transformers? If the company's still in business-look in EEM-they may be able to tell you. Check with some organ techs. If it isn't a Hammond, Allen, Leslie, or Wurlitzer all bets are off. What connectors does it have and where? www.mitatechs.com is a good source for finding organ techs... |

Thanks, Bret. These were really stripped, and there isn't anything much to ID them, except the power XFMR. Original connectors removed. It looks like the OPTs were retrofitted with some Hammonds, and I have the specs on those. The power XFMR is 512-23629A. These will make a nice amp . . . I've been working on layouts. Much obliged, Jon |
