Re:Replacement transistors for Q1 and Q3

2010-02-17 by Marcus Wilson

Hi There!

I have posted about suitable replacements for these two diodes, so the  
info is in the archives here,

it was about 2-3 years ago, so you will need to do some digging to  
find it, or use site search

if you ahve major hassles, i'll look for my records, but my friend..  
the info is in them there archives!
