I finally received my Lil' night Train yesterday and the amp is great looking. Call me crazy, but I didn't waste any time with the cheap Chinese tubes that the amp comes with. After reading many threads about tube variants and types, I went into my stash of NOS tubes to replace. V1 NOS 6072 (12AY7), V2 NOS 12AX7 and V3 NOS 12BH7. Fired up the filaments and wailed. I am plugged into an old vintage Caliphone phonograph speaker cab that I installed a Carvin 12 inch Vintage speaker. Sounds great but I believe it could sound better. Considering the C19 mod or even changing out the cap for an Orange Drop of a different value. Anyone else try this?
