D67 Oscilloscope

I bought an oscilloscope from ebay as a non-worker for repairs, turns out it works.

Some amusement

The scope was being sold on ebay as an auction lot from a house clearance, the description read like this:

	  THIS CAME OUT OF A HOUSE CLEARANCE. I HAVEN'T A CLUE WHAT IT
	  IS OR WHAT IT DOES. COMES WITH 2 LEADS AND A CONNECTOR I
	  HAVE PLUGGED IT IN BUT COULDN'T GET ANYTHING TO HAPPEN BUT
	  DON'T KNOW WHAT BUTTONS I SHOULD BE PRESSING ANYWAY. I'M
	  SURE IF YOU KNOW WHAT YOU ARE DOING YOU MAY BE ABLE TO GET
	  IT TO WORK BUT BEING SOLD AS SEEN FOR SPARES / REPAIRS.
	

So I put a bid in for £25 which was reasonable for a non working scope, in my opinion and it arrived some time later - to my surprise there is nothing (functionally) wrong with it, it switched on without a hitch! No burns on the screen, and all the buttons and switches work well with very little noise. The original owner has changed the fine control on the 2ndary sweep speed, but other than that all original and in reasonable nic :)

Some photos

I took some photos of the inside and outside of the scope, and have given it a breif clean - but given that it's a 1971 scope and likely never had a good clean, I'm sure the reader can imagine how dirty it is inside. To clean it properly I'll need to buy some rubbing alcohol and a can or 5 of compressed air

Initial power on test - It works!

The left hand side of the scope before cleaning. This side mostly seems to handle time/div functions (ie trace horizontal), and has the power supply in it

The right hand side of the scope before cleaning. This side does volts/div and input amplifcation.
