The second 2012 seminar concluded today. Bruce and Terry (Teri?) did a great job, good people and I really enjoyed spending some time with them. The group of guys attending were also a great bunch, mostly gigging musicians getting their feet wet in tube amp technology. I think I was the only one with previous amp building experience.
I spent a couple of hours this evening dialing in tones with the amp. I'm old school, play an 18 watt Marshall clone, a Hiwatt style amp and recently built a Trainwreck inspired amp. So, none of them are high gain monsters (with the exception of the Trainwreck which needs to played at high sound pressure levels to drive the output tubes into distortion). The cascading gain stages of this build feature lots of preamp distortion and it's taking a bit of twiddling to get the sound I want, I'm warming up to it quickly though. Very forgiving...LOL...you can get away with some slop with this much gain.
I didn't take time for pictures, didn't even ask Bruce if it was kosher. Put my head down and started breathing solder fumes. All day Saturday was spent assembling the amps. On Sunday Bruce put on a lecture explaining what goes on in the circuit. Great info, I had an "aha" moment or two.
Thanks again to Bruce, Terry and all who labored behind the scenes. I'm exhausted, I can only imagine how much energy they put into this.
