Dinky little 2-valve Chinese pre-amp

[Joe]

My mis-understanding again (so nothing new there!). I thought that the one Nick posted was to illustrate use of a 12V HT whereas the one under discussion was all-valve, and therefore as much use as a chocolate tea-pot. If it's got some sort of output stage it would at least have a hope of operating headphones. I'm also so used to LM317Ts that I failed to recognise one of the LZ version.

It's odd as there are others on sale described as hybrids.

I'm NEARLY tempted to by one to see just what is what.
