Bipolars were also what I started working with.

neat job!

As much as I like dthe bipolar transistors.. i also agree.. I'v built way 
more ( and more stable ) circuits using a fet of some sort...   Though have 
to throw kudos to the other stuff.. darlington pairs, and scr's.. etc. 
'Bout the only thing i did with bipolars much was audio application.. .. 
input and output stages.. but thru the years... mosfets became the thing for 
the output stages...   .. Oh well..

>You do remember having to repair TV's don't you.

I can remember doing it for a few years... When it got to the point that you 
just replaced the mainboard.. I lost interest..  ( so did everybody else... 
big companies pretty much obsoleted small appliance repair.. )
