I tried to take a shot with my ancient point and shoot camera. Not fuzzy but the exposure drowns out the detail in the current meters.
The amp sounded good tonight. I'm tempted to draw comparisons but it's too soon. I played a little violin piece just before I quit tonight that stole my breath for a moment. Total midrange magic. It doesn't fully complement every type of music I'm finding but when it does it is awfully beguiling.
I am brand new to manual bias so I didn't know what to expect. Just changing the current from 32 to 34 mA on the 45s produced a pretty noticeable change in sound. I thought running the tubes harder would make them sound edgy but that isn't what happens at all, it just sounds better all around with more current. In the future I'll bump it up to 36 and eventually try out 38 as well which is where Glenn ran them. He told me not to go above 40 and I have a suspicion that 40mA would probably halve the life of the tubes or worse since the general opinion is that even 38mA is running them hard. It will be fun to experiment.
