Dear Touring Gents,
It has been brought to my attention that I need to emphasize some points. Touring participants may want to print out these points.
1) The 10A needs 30 minutes to warm up. The sound will change somewhat, to drastic. So this is important.
2) The 3 position switch (near the output jacks) is really far more than a bright, neutral, dark switch, affecting far more than just the tonality. Please make sure you audition the preamp in all the positions.
3) Turn off the preamp and wait at least 4 minutes before "flipping" the tonal switch.
4) Be sure to try the AC polarity switch (near the fuseholder) in both directions. This can be done on the "fly" and it is possible the mute function will activate. Just wait 45 seconds to 1 minute for the mute to cycle.
Please don't be afraid to experiment with these switches.
Also keep the dotted ends of each IC together. Try reversing the ICs for the best sound.
Thanks, again, for the participants who signed up.
