"flipper"
I just received a pair of SE OPTs that were claimed to be from a
stereo console with 6BQ5 outputs. So far so good as that's precisely
what I wanted to build.

Problem is, when I put 120.7 AC on the primary I get 1.9VAC out for a
ratio of 63.5/1, which comes to roughly 32k/8 ohms, or 16k/4 ohms, and
from what little I know of 6BQ5 characteristics that doesn't make any
sense to me. I mean, 8K would be good but a console with 2 ohm
speakers?



** In the 50s and early 60s, 2 ohm speakers were not uncommon in tube radios
and budget stereos.

Also, there may have been 2 speakers wired in parallel.

Fender made a number of tube guitar amp models in the 1960s that were
matched to a 2 ohms load.
