Hi JTW
Well it's just via finger test. My finger would get burn if I touch it for more then 5 secs. Now I have another thought.
Since both transistors are just to power the buffer, why not build a dedicated supply & just bypass & solve the
heat issue. Question, besides removing the transistors are there anything else to remove & also is the new power
supply connected at C28 & C29 ?
Many thanks
