RE: Advanced Four Phase Cyrclotron

Posted by Ralph on February 10, 2010 at 08:42:16:
In order for that test to be fair, you would have to remove half of the power tubes in each amp, so that the result would have the same number of tubes as a single M-60.

We've done that before- for a long time we had the idea of 'just by a second one' as a means of increasing amplifier power by simply monostrapping the amps.

What we found is that was not what the market wanted. That's why we make different models. But in the process, we found that the output impedance in such a hookup, given that there are an equal number of tubes, is unchanged.
