In Reply to: The heat of a headphone OTL amp.... posted by wangmr on August 11, 2014 at 06:19:10:
The Bottlehead Crack w/ the Speedball upgrade comes in at $391. As stated it deals with high impedance headphones beautifully. Mine is mated with Sennheiser 650 phones and I couldn't be happier. The heat of the big WE 6080 dual triode output tube is negligible. The 12AU7 is barely worth noting. After a few hours the power transformer will get mildly warm to the touch.
The heat noted as a general question may be worth a small stab... With enough tube amps running during a summer's night one may be tempted to kick on the AC and that will effect the sound! :)
