Now work through this assuming the user has a balanced power conditioner or is using an isolation transformer. Neither of these scenarios is particularly unlikely.
If the music you listen to is Switch on Bach or even just organ music in general, the delineation between power with music and continuous sine wave power into a resistor are not separated by much.
Tomorrow I will be contacting my credit card company to dispute the charge for this amp. The return was received on the 28th and a refund was promised (with official looking paperwork), but it hasn't materialized.
There are three of us who have tested these amps and gotten similar results. How many different people do you need to test one of these in order to satisfy your curiosities?
This was as dealt with in the first two amps I measured in the first thread, but it keeps getting brought up for some reason. I measured these amps both ways and they are slightly worse when you measure them the way Bob says to.
Do keep in mind that Bob does not dispute any of the measurements...
The #45 amp made its power but had one filament winding shared between the tubes with cathode bias, so crosstalk was problematic. The preamp had sufficient noise issues that I had to convert the tube heating to DC to get it quiet. I remember the 807 amp not making nearly the power claimed...
