Today i change the heater using LM317. When the vout is not connected to the heater, i measured 6.3V but when it connected to the heater, it was only 1v and the tube didn't light up?

This amp use a swiching power supply for the heater, if i change it to a linear regulator like LM317, will it improve sound quality? If i use a LM317, do i need to apply some diodes and capacitor to filter the current?

My amp has quite imbalance channel, it go about 60% on the right and 40% on the left. What can be the source of problem?

I have heard both. The Hifimediy and Odac share the same character, at first listen, it will be very hard to tell the different but the more listen i find that Odac is clearer, better definition, more 3d sound stage. Thats not a huge...

Sorry for my silly question but can the MSSH modify to using only 1 tube like the other simple 12au7 hybrid amp?

But  the Mini3 is simple a cmoy with a ground channel and better opamp that outperform the regular cmoy and both the M3 and B22 use a ground channel too so what is the benefit of a ground channel?
