<DIV><FONT face=Arial size=2>Thanks to all who replied, I have tested a bunch of
the transistors and the hFE varied from about 130 to 200, I found about 8 that
matched at 166, do you reckon this would be ok to use in the soundlab VCO's?
>From what I can gather a matching hFE is better than just randomly sticking any
pair in but not as precise as the traditional method, no?</FONT></DIV>

<DIV><FONT face=Arial size=2>Also re the tempco's would these be
suitable?</FONT></DIV>

<DIV><FONT face=Arial size=2>The design calls for 2k PTC but would I be able to
use the 4.7k above if I changed the circuit a bit? Any thoughts
welcome!</FONT></DIV>

<DIV><FONT face=Arial size=2>BTW I promise to post some pics up when I finally
finish the Soundlab, it will look pretty cool in a nice old hardwood cigar box
with an aluminium panel and cool wide skirt numbered
knobs.</FONT></DIV>
