Mr. Truba, Please send information about your low-wattage tube amplifier. But the entire industry has been slow to learn and accept this. The solutions they try for the volume problem are everything except the most obvious and straightforward. So I have been encouraging guitarists to ask for truly low-power tube amps. My site has information about products and projects which are similar to yours.
