Ok. it's not easy to get switching transformer here.. if only use those schematic for plate voltage and 2x batery 9v plus 1x 1.5v batery, this one will work ?

do you mean using this one...

Using 7805 dan resistor.. or maybe Using Battery 1.5v I found Phono Amps schematic using 6088 http://members.aol.com/sbench/6088pre3.html I found Pre-amp Schematic using 534AX Pentode http://www.dogstar.dantimax.dk/tubestuf/gallery4.htm Can I build like soha / yaha using op-amp ?

I have 6 pcs 6088 tube, with this spec : I want to build tube Amps with 2x9v battery. Anyone has headphone amps schematic with this tube

try to change psu for U55SX it will sound warmer. the bad thing it's use too much usb bandwith.

there many amperex 7316.. can you give more description.... Brand.. (Orange Globe / Bugle Boy , etc) Getter type... Color Label.... Long Plate / Short Plate Plate Color Year Manufacturer.
