RE: Losses in Output Transformers

As far as I know, the numbers are RMS watts. And I haven't had this issue with everything. For example, single-ended 6V6 and 6BQ5 amps perform exactly as they should, even with relatively inexpensive transformers. However, amps I built recently with tubes and voltages similar to those I outlined produced output in the low- to mid-30s, not the 50W shown in the sheets. I take power readings just below clipping at 1kHz. The tubes simply aren't producing what the sheets show, at least not at the output of the transformers.
