Sorry the heading to this should be "5100 weirdness(!)" - I have bought a 5100 preamp/amplifer. It has had a little bit of shonkey work done on it, which I will need to ensure is OK, or can be reversed - it appears that someone has inserted a trimpot just before the transistor pre-drivers - only on one channel - i suspect perhaps to make the (usually fixed?) bias adjustable? I will add photos soon to show what I mean.
In the meantime I'd like help with finding a modern and obtainable replacement transistor for Q9-10 & 101-102 - this is listed by McIntosh as a BC168C - any equivalent that anyone recommends? There are four types that come up at the equivalent site that I use (BC238, BC182L, 2N3710, KT373A), however these arent obtainable from my usually NZ supplier, and no details are described of the equivalent's hFE grade. Can anyone recommend any other type? thanks!
