6L6 SE UL power amp in a wine bottle box

This JJ 6L6 and 12AT7 top-of-range Psvane tubed power amp has been constructed in (and on) a $9 gift wine box. The box has been finely sanded beeswaxed twice. There is an external 12V transformer and another inside to step-up the HT voltage. Resistors are metal film and inter-stage caps are Solen.

The amps sound is solid, grounded and well rounded. Only a few watts but plays more than loud enough through my 99db efficient 15" Beyma concentric 170ltr speakers.
