Cool- I tried it for a couple minutes- the connections on the Heathkit are for the speaker, but there is also a voice coil, and this does have a center tap on the transformer, which looks like the one on the speaker in the schematics. The center tap is marked B+, and it looks like I could connect the show with the HK unpowered, Blue/white tr and Green/white tr into the speaker, and the white and green into the output transformer, jumpering from the green/white tr to the B+ connection, and come out the same. Check out the schematic for the AG-10 on page 20 of the partial HK manual at BAMA: ftp://bama.sbc.edu/downloads/heath/t3/pages/20.gif
or: ftp://bama.sbc.edu/downloads/heath/t3/t3.djvu and go to page 12.
It looks like if I make the connections above, with no power to the Heathkit, I should be ok.
I have not been able to make that work yet, but I will retry with the B+ hooked in. If nothing still, then I'll have to grab out the speaker.
Please, Take a look, let me know what you think...
Thanks!
