 I'm really curious who has built this amplifier, how it sounds? Looks like it is very serious made amplifier.

Someone in my local area who has listened to this amplifier told me, this OTL is one of the best tube amplifier other than NYAL OTL-1 driving a pair of JBL horn speaker with zero impedance autoformer.

 I have built a pair of Kimmel's amplifiers. What do you want to know?

 OTL + Autoformer = OT

IMHO, whatever the OTL be, it would be better to use high impedance speakers instead of autoformer-low impedance speakers.

In case of autoformer, it would be wise anyhow to have some means to switch out the autoformer in case of low power demand.
