"Pictured here is the front (component side) and back tracks side of a transistor ladder filter that I built some time back- found in my protoype graveyard! I'm going to fire it up again in the next couple of days. All built from parts that date between 1965 and 1969!"
"The Gold IC there is a cramic housing containing a Fairchild LM108D Op amp- the rest, apart from the CA3080 (Can) are 1960's transistors and Dual Transistors in metal cans!"
