It's my decrete headphone amplifiler. This amp's Schecmatic is a Kelvin Gilmore's from headwze website. Sound is very clear and powerful. It's just my taste^^.

I've not found 2SK389 and 2SJ109.

So, I replced 2SK170/2SJ74(single type) instead of 2SK389 and 2SJ109.

no problem at all. But probabley need a pair matching of FET.

 

[lineup]

yes, 2SK389 2SJ109 are difficult to find

2SK170/2SJ74 works well here

Whats wrong with a few smallish .jpgs attached to the thread.
