I wish I knew! The $6K Bigger Ben audiophile amp I linked to in this thread has a JJ ECC803S in their website's product pictures, which is a perfect example of what I mean. Don't know if that is common or an outlier- some audiophile or EE types with much deeper knowledge about amp topology than me would need to chime in about differences. The original production of all these tube types & specs were for military & aviation purposes,. The entire consumer electronics category (home AM/FM radios, guitar amps, PA systems, organs, etc.) used availble tubes that were already being massed produced for other purposes. Are current production "audiophile" grade 12AX7s & 6L6s being made to some totally different specs?Again, I'm no tube expert here, but I don't see how 'dual use' tubes are going to work. If they did, it would have been done already.
The tubes we use add gain, clipping and distortion.
The tubes they use don't.
Am I wrong?
