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

I doubt one exists.

How are you going to supply the 1.5 volt filament supply with 2 x 9 volts?

This tube is a pentode .... what are you going to use for an output transformer?

Using 7805 dan resistor.. or maybe Using Battery 1.5v

I found Phono Amps schematic using 6088

I found Pre-amp Schematic using 534AX Pentode

Can I build like soha / yaha using op-amp ?

The completely backwards approach. I have something and want to use it.

Pencil tubes not really suited for this.

Send the tubes off to pete millet and he can put them in his whacky portable

for you. Not going to be cheap. You are going to need the switchers he uses to

raise the B+ to something like 48 volts. Then use the solid state buffers to drive

the headphones.

48 volts and 1.5 volts both come off the switcher.

do you mean using this one...

not quite but close. pete used an off the shelf switching transformer

with 2 secondaries. one was used for the filaments.

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 ?
